A feasibility study undertaken by the Water Research Centre to capture 30,000 items from Water Pollution Abstracts in machine readable form is reported. The equipment used to capture a one year sample of these abstracts is the Kurzweil Data Entry Machine (KDEM), a computer controlled scanning device which captures lines of text for direct output to magnetic medium. After further manipulation using word processing equipment and indexing using the ASSASSIN suite of programs, the abstracts are to be added to the publicly available database, AQUALINE. The relevance of this bibliographic material to the water industry is discussed with the aid of citation analysis of four relevant journals. The speed and accuracy of the technique is described and the final cost reported is far less than the expected cost for re‐keying the data. The technique should have widespread applications for related tasks, and should become more common as similar equipment to the KDEM becomes more readily available.

In order to succeed in an action under the Equal Pay Act 1970, should the woman and the man be employed by the same employer on like work at the same time or would the woman still be covered by the Act if she were employed on like work in succession to the man? This is the question which had to be solved in Macarthys Ltd v. Smith. Unfortunately it was not. Their Lordships interpreted the relevant section in different ways and since Article 119 of the Treaty of Rome was also subject to different interpretations, the case has been referred to the European Court of Justice.

The case we report elsewhere in this issue, in which a beverage described as “flavoured and coloured cider,” was sold to the public as “British Wine” at more than double the price of the genuine product, raises issues of importance not only to the general public, but also to producers and public authorities concerned with the administration of the Food and Drugs Act and other measures protecting the interests of the consumer. What standards of quality can the public reasonably demand from the supplier of British Wines? Owing to the great variety of wines produced and the multiplicity of processes involved, it has not been found practicable in any part of the world to devise a universally acceptable definition of wine, but clearly the primary condition which entitles a beverage to this description is that it should be produced with the product of the vine as a basis, at least in the case of those varieties which are marketed under foreign appellations. The consumer may also reasonably expect, and the conscientious wine merchant ordinarily takes care to provide, a wine which has keeping qualities, such as can be guaranteed only in a beverage which contains enough alcohol to preserve it. The descriptions “Port Type” or “Sherry Type” which commonly appear on British Wine labels entitle the purchaser to expect a beverage as nearly approaching the quality and characteristics of the imported variety as the Customs and Excise Regulations permit. Imported Sherries or Ports, thanks to the right granted to producers to fortify them, normally contain some 20 per cent. of Ethyl Alcohol, or 35/36 degrees of proof spirit. This right of fortification is denied to British Wines, which, therefore, must contain a lesser degree of alcohol obtained by natural fermentation. The purchaser, nevertheless, expects a beverage of the same keeping qualities as the imported variety. It is true that other wines keep in bottle at much lower strengths, but table wines of this character are usually consumed the same day as they are opened, and are not, like Ports and Sherries and their substitutes, kept for days or weeks in the cupbdard or on the sideboard. In our opinion, such keeping qualities cannot be achieved by British Wine makers with less than 16½ per cent. of alcohol, or 28/29 degrees of proof spirit, with a corresponding content in sweetness which materially helps to preserve the wine. In the drier types a still higher degree of strength is necessary. While it is true that the foreign and colonial class of N.E.25 and N.E.27 proof spirit are imported into this country, these wines are greatly helped by their high degree of sweetness which the British Wine producer can only reach, under existing regulations, at the expense of the alcohol necessary to ensure the keeping qualities demanded by his customers. In any regulations framed to protect the consumer, the above considerations, which are based on experience and traditional practice, must be constantly borne in mind.

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

The final report of the Butter Regulations Committee has now been published and it is earnestly to be hoped that Regulations based on the Committee's Recommendations will at once be framed and issued by the Board of Agriculture. It will be remembered that in an Interim Report the Committee recommended the adoption of a limit of 16 per cent. for the proportion of water in butter, and that, acting on this recommendation, the Board of Agriculture drew up and issued the “Sale of Butter Regulations, 1902,” under the powers conferred on the Board by Section 4 of the Food Act of 1899. In the present Report the Committee deal with the other matters referred to them, namely, as to what Regulations, if any, might with advantage be made for determining what deficiency in any of the normal constituents of butter, or what addition of extraneous matter other than water, should raise a presumption until the contrary is proved that the butter is not “genuine.” The Committee are to be congratulated on the result of their labours—labours which have obviously been both arduous and lengthy. The questions which have had to be dealt with are intricate and difficult, and they are, moreover, of a highly technical nature. The Committee have evidently worked with the earnest desire to arrive at conclusions which, when applied, would afford as great a measure of protection—as it is possible to give by means of legislative enactments—to the consumer and to the honest producer. The thorough investigation which has been made could result only in the conclusions at which the Committee have arrived, namely, that, in regard to the administration of the Food Acts, (1) an analytical limit should be imposed which limit should determine what degree of deficiency in those constituents which specially characterise butter should raise a presumption that the butter is not “genuine”; (2) that the use of 10 per cent. of a chemically‐recognisable oil in the manufacture of margarine be made compulsory; (3) that steps should be taken to obtain international co‐operation; and finally, that the System of Control, as explained by various witnesses, commends itself to the Committee.

The question whether grape juice may or may not be preserved with sulphur dioxide is one which arises occasionally as a result of a certain ambiguity in the wording of the First Schedule of the Regulations. It is not a matter of opinion, as some would hold, but a matter of law, and, as such, should be fully appreciated by the legal advisers of local authorities, if not by Public Analysts. Item 4 of the First Schedule of the Regulations states that “Unfermented grape juice and non‐alcoholic wine made from such grape juice if labelled in accordance with the rule contained in the Second Schedule to these Regulations” may contain 2,000 parts of benzoic acid per million of grape juice and does not admit of the presence of the addition of any sulphur dioxide. The Second Schedule prescribes that, if the proportion of benzoic acid present in grape juice exceeds 600 parts per million, it shall be labelled with a declaration to that effect and also with the words “and is not intended for use as a beverage.” Item 5 of the First Schedule of the Regulations states that “Other non‐alcoholic wines, cordials and fruit juices, sweetened or unsweetened” may contain either 350 parts of sulphur dioxide per million parts of preparation or 600 parts per million of benzoic acid. Normally one would infer from this that grape juice to be used as a beverage falls under Item 5 of the Regulations, but that, if for some special reason it is not to be so used, it is permitted to contain up to 2,000 parts per million of benzoic acid provided that it is labelled to the effect that it is not to be used as a beverage. It should be noted that Item 4 does not read that grape juice and non‐alcoholic wine made from it may contain 600 parts per million of benzoic acid, but that, if labelled in accordance with the rules contained in the Second Schedule, it may contain 2,000 parts of this preservative. If grape juice were only allowed to contain benzoic acid as a preservative and if sulphur dioxide were prohibited under all circumstances one would have thought that Item 4 of the First Schedule would have been drawn up to indicate this, but no such indication is given at all. At the time that the Preservatives Regulations were issued it was fully recognised that sulphur dioxide was employed as a preservative in grape must. Whilst the Departmental Committee was considering the matter of preservatives and colouring matters the Ministry of Health issued a Report on Public Health Subjects, No. 24, entitled “Report on the Composition of Commoner British Wines and Cordials (Alcoholic and Non‐alcoholic),” by Dr. G. C. Hancock, C.B.E., one of the Medical Officers of the Ministry, together with a Report by the Government Chemist on the Examination of Samples. In the introduction Dr. G. Newman, the Chief Medical Officer to the Minister of Health, writes : “The most important of these materials are preservatives, and Dr. Hancock mentions the considerations which underlie the use of these substances in the manufacture of British wines and cordials. As, however, the question of preservatives and colouring matters in foods is being considered by a Departmental Committee of the Ministry he has made no specific recommendations relating to the use of these substances.” On page 4 at the end of the sixth paragraph Dr. Hancock refers to grape juice or must and says : “It is sent here in a highly concentrated form and is usually ‘sulphured,’ i.e., treated with sulphur dioxide in order to inhibit fermentation during transit.” Among other information placed at the disposal of the Departmental Committee was Dr. Hancock's report and in the Final Report of the Committee, also issued in 1924, paragraph 57 states: “Sulphurous acid and sulphites are extensively used in beer and alcoholic wines, to some smaller extent in non‐alcoholic beverages, and in preserving fruits and fruit juices, dried fruits, gelatine and sausages. … In the case of beer, wines, fruit and fruit juices the introduction comes partly from the treatment of the vessels of preparation and storage, partly from the materials used and partly from the actual addition of preservative in the course of manufacture or treatment for storage.” When considering the question of alcoholic wines, Foreign and British in detail, the Committee stated their opinion in the following words (para. 144): “Foreign and British wines are by no means closely related products. The former are the naturally fermented produce of the grape, while the latter are rarely derived from fresh fruit and are far more commonly prepared from a basis of dried fruits, rhubarb or imported grape must, fermented after the addition of sugar and flavouring materials, such as dried ginger‐root, orange peel, alcoholic essences or foreign wines. Considered from the point of view of preservatives, however, they have two features in common, (a) that the alcoholic content is very similar in each, (b) that sulphur dioxide is the preservative which is usually favoured (in addition to the alcohol present) to prevent secondary and other undesirable fermentations and sourness.” Instead of making any suggestion that the use of sulphur dioxide should be prohibited in grape must, the Committee draw their conclusion in paragraph 147 in the following words : “Our conclusion is that while in general preservatives should be unnecessary in alcoholic wines of ordinary strength, there may be circumstances which render the entire elimination of preservatives impracticable for the present. We think, however, that no other preservatives than sulphur dioxide should be permitted, and that this substance should not be present in amounts exceeding 3 grains of sulphur dioxide free and combined per pint (343 milligrams per litre).” This recommendation was adopted in the Draft Statutory Order issued in February, 1925, but, when the final Order was published, the quantity of sulphur dioxide permitted had been increased to 450 parts per million, making the law in this country agree with that already adopted in France. The recommendation made by the Departmental Committee was put forward after the Committee had commented on the fact that British wines are largely prepared from “imported grape must.” It seems remarkable that the Committee should have expressed the opinion that sulphur dioxide is used for sulphuring the casks, that sulphur dioxide is permitted in the completed wine, if it is not allowed to be present at intermediate stages, and that a Regulation was made by which benzoic acid only could be present in the unfermented grape juice, if this is not permitted to be present in the fermented alcoholic wine. When benzoic acid has once been added it cannot be eliminated and, as recognised by the Departmental Committee, benzoic acid is undesirable from the fermentation aspect. Had there been any intention to prohibit the presence of sulphur dioxide in unfermented grape juice, the Regulations would have rung the death‐knell to the manufacture of British wines, which have been produced in increasing volume during the last twenty years. Further, if there had been any intention to prohibit the addition of sulphur dioxide to grape juice, one cannot but express surprise that the importation of such juice has not been suppressed long ago by the Customs Authorities, since Section 8 (1) of the Regulations lays the responsibility for the control of Imported Articles of Food on the Officers of Customs and Excise and, through them, on the Government Chemist. The failure of the Government Chemist to condemn grape must containing sulphur dioxide cannot be due to his ignorance of its presence because the chemical analyses for Dr. Hancock's Report were carried out by the Government Chemist, and on page 58 of the Report No. 24, to which reference has already been made, analyses are given of two French musts containing 360 and 302 parts of sulphur dioxide per million respectively and of an American concentrated must containing 63 parts of sulphur dioxide per million. If we now look at paragraph 153 of the Final Report of the Departmental Committee we find that the matter of preservatives in certain non‐alcoholic beverages is dealt with in the following words: “We consider that sweetened and unsweetened fruit juices, syrups, cordials, non‐alcoholic wines and articles of similar composition such as certain well‐known proprietary cordials, are peculiarly liable to develop moulds and to ferment, owing to liability to exposure on the consumer's premises between the first opening and final consumption, and we think that on this account they may under present trade conditions need the addition of a small proportion of preservative. We therefore suggest that the presence either of benzoic acid up to 5 grains or of sulphur dioxide up to 3 grains per pint might be considered.” These recommendations were adopted in the Draft Rule and Order, issued in February, 1925, and there was no reference in this Draft indicating that grape juice was to be treated in any manner distinct from other fruit juices. The introduction of Item 4 in S.R. & O. 1925, 775, came as a complete surprise to everyone and the general surprise felt was mentioned by Mr. C. A. Mitchell (now Dr. Mitchell) in a paper read before the Medico‐Legal Society on Tuesday, April 20th, 1926, with the Rt. Hon. Lord Justice Aitken in the chair. Mr. Mitchell made the following statement: “The fourth item in the Schedule is one at which one can only stare and wonder how it ever came there. According to this regulation unfermented grape juice and non‐alcoholic wine made from it, may contain the enormous quantity of 17 grains of benzoic acid per pint, provided that it is labelled in accordance with Schedule II. I am fairly familiar with the cases which have been brought into Court during the last 20 years, but I cannot recall an instance of a non‐alcoholic wine (labelled or unlabelled) containing an amount of preservative equivalent to this quantity of benzoic acid.” Mr. Mitchell then proceeds to explain that the most probable reason for the introduction of this item into the rule is that it is intended to apply to non‐alcoholic sacramental wine, which is not to be used as a beverage, but which is taken a little at a time and is expected to keep for long periods, when the bottle has once been opened. This is, in fact, the position so far as I am aware and there was never any intention of any restriction on the use of sulphur dioxide in the ordinary way as a preservative in unfermented grape juice so long as the amount present did not exceed 350 parts per million.

The Equal Pay Act 1970 (which came into operation on 29 December 1975) provides for an “equality clause” to be written into all contracts of employment. S.1(2) (a) of the 1970 Act (which has been amended by the Sex Discrimination Act 1975) provides:

Knight's Industrial Law Reports goes into a new style and format as Managerial Law This issue of KILR is restyled Managerial Law and it now appears on a continuous updating basis rather than as a monthly routine affair.

Purpose: To describe how an approach to instruction that intentionally considers elements of motivation and engagement, intensity of instruction, and cognitive challenge can accelerate the reading achievement of lower-performing readers by giving them access to and support to meet reading and knowledge building with success.

Design: The authors discuss a set of high-leverage practices squarely under the teacher’s control. Grounded in longstanding and rigorous research, the integrated set of practices have been shown time and time again to accelerate achievement beyond typical growth while also intentionally considering the experiences, cultures, and linguistic knowledge students bring to the classroom. The re-conceptualized approach forefronts student agency and engages students in meaningful interactions with text to build knowledge of the world they live in.

Findings: The authors illustrate the comprehensive approach through a composite vignette drawn from work with teachers and students in school and clinical contexts. The focus of the vignette is on the actions of the classroom teacher who is working to meet the needs of three struggling readers within the broader context of her 5th-grade classroom, while also establishing a coherent instructional approach with fellow teachers.

Practical Implications: By re-conceptualizing their approaches to working with struggling readers, teachers increase the likelihood that students will not only develop component skills related to reading but also integrate these components and develop the conceptual expertise that anchors future reading and learning.
