Although there have been extensive studies on the hydrological and erosional impacts of logging, relatively little is known about the impacts of conversion into agricultural plantation (namely rubber and oil palm). Furthermore, studies on morphological impacts, sediment-bound chemistry and forensic attribution of deposited sediment to their respective sources are scarcer. This chapter introduces the potential for using the multi-proxy sediment fingerprinting technique in this context. Featuring pilot projects in two major flood-prone river systems in Malaysia, the studies explore application of geochemistry-based sediment source ascription. The geochemical signatures of sediment mixtures on floodplains were compared to sediments from upstream source tributaries. The tributaries were hypothesised to have different geochemical signatures in response to dominant land management. The first case study took place in the Segama River system (4,023 km²) of Sabah, Malaysian Borneo where a mixture of primary forest, logged-forests and oil palm plantations were predominant. The second case study was in the Kelantan River Basin (13,100 km²) with two major tributaries (Galas River and Lebir River) where logged-forests and rubber and oil palm plantations are dominant land-uses. Both case studies demonstrated the applicability of this method in ascribing floodplain deposited sediment to their respective upstream sources. Preliminary results showed that trace elements associated with fertilisers (e.g. copper and vanadium) contribute to agricultural catchment signatures. Alkaline and alkaline-earth elements were linked to recently established oil palm plantations due to soil turnover. Mixing model outputs showed that contributions from smaller, more severely disturbed catchment are higher than those from larger but milder disturbed catchments. This method capitalises on flood events to counter its adverse impacts by identifying high-priority sediment source areas for efficient and effective management.

THE influence of wireless on libraries is marked. As a method of publicity it is unmatched. On April 20th the new secretary of the Library Association, Mr. Guy Keeling, joined the number of library broadcasters with a talk from 2 LO on “What Your Public Library can do for You.” The announcer said he regarded the talk as a fresh mark of the co‐operation between the B.B.C. and the public libraries which had been so fruitful in the past; and Mr. Keeling made his first real public appearance as Secretary with a clearly Stated account of our ordinary activities, enlivened with humour, and delivered in excellent manner. Together with all those who have any vision in the matter, he looks forward to co‐operation between all libraries.

Blake is relatively well-known, but who was J M Robertson? What's his connection with George Spencer-Brown? And how exactly did J M Robertson influence George Spencer-Brown?

George Spencer-Brown (1923–2016) is the author (among other works) of the undeservedly little-known book, Laws of Form (1969/2011), which was a key inspiration for Niklas Luhmann (1927–1998). But what inspired George Spencer-Brown? This paper explores two key influences on George Spencer-Brown and his work: the English poet and artist, William Blake (1757–1827) and the Scottish rationalist, politician and author, J M Robertson (1856–1933).

The paper points to a broken link between George Spencer-Brown's work and Niklas Luhmann's.

These questions are explored from two perspectives: first, George Spencer-Brown's works and their debt to (1) Blake's work, from which he quotes in a number of instances and to (2) J M Robertson's (in particular, the latter's Letters on Reasoning (1905) and Rationalism (1912)); second, my personal connection to Spencer-Brown, who mentored me through Laws of Form and with whom I developed a close friendship involving regular weekly telephone conversations for the greater part of the last four years of Spencer-Brown's life. I share anecdotes and stories that connect George Spencer-Brown and J M Robertson that span George Spencer-Brown's lifetime – from his school days to his dying days. Both Blake's and Robertson's influences are relevant to Spencer-Brown's view of morality. The paper looks at specific connections between Blake's work and J M Robertson's on the one hand and George Spencer-Brown's on the other.

The Annual General Meeting of the Pure Food and Health Society of Great Britain was held at 20, Hanover Square, W., on February 27, the President, Sir PHILIP SASSOON, Bart, M.P., in the chair. The Secretary, Mr. A. E. MOORE, read the following report of the Executive Committee:—

Dr. F. J. H. COUTTS'S report to the Local Government Board on an inquiry as to condensed milks, with special reference to their use as infants' foods, has been issued as No 56 of the new series of reports on public health and medical subjects.

From what was said in the previous article on this subject, it is obvious that a new profession has arisen in consequence of the passing of the Food and Drugs Acts, and of the fact that their execution is now compulsory on all the local authorities legally concerned with the matter. This profession, under the fostering influence of certain scientific and academic bodies, now includes a considerable number of individuals who, in their general culture and education, as well as in their special scientific qualifications, are at least on a par with the members of the older so‐called “learned” professions. In the course of the early development of the analytical profession, as a body, the old Society of Public Analysts was a most potent influence for good, and did, and still does under another but unfortunate name, very excellent work in collecting and publishing any additions that are made to our scientific knowledge of matters connected with the analysis and adulteration of food by the scattered workers in this country and abroad.

Some misconception appears to have arisen in respect to the meaning of Section 11 of the Food and Drugs Act, 1899, owing, doubtless, to the faulty punctuation of certain copies of the Act, and the Sanitary Record has done good service by calling attention to the matter. The trouble has clearly been caused by the insertion of a comma after the word “condensed” in certain copies of the Act, and the non‐insertion of this comma in other copies. The words of the section, as printed by the Sanitary Record, are as follows: “Every tin or other receptacle containing condensed, separated or skimmed milk must bear a label clearly visible to the purchaser on which the words ‘Machine‐skimmed Milk,’ or ‘Skimmed Milk,’ as the case may require, are printed in large and legible type.”
