DURING 1943, we published two papers, both from foreign sources, on electric gauges to measure the strains in aeroplane structures. The second of these, which logically should have come first, appeared in our April issue and was an MAP. translation from the German which covered the theory of electric resistance strip and ring gauges. The other, which had appeared earlier, in‐our February issue, was an S.A.E. paper by MR. C. R. STRANG dealing with practical technique in the application of strip gauges as developed by the DOUGLAS AIRCRAFT COMPANY. Owing to the limitations on paper the February issue is now completely out of print—not, perhaps, a matter of great moment since the article is now mainly of academic interest—and there are only two or three copies of the issue containing Mr. STRANG'S most interesting account still available. We mention this to save disappointment on the part of those who may be led by the further article on the subject in this, issue to wish to obtain them. MR. KING now to a large extent completes the picture and rounds off what may be considered a series by giving information on the form in which the gauges should be applied and the method of interpreting the resulting readings.
