Abstract
WE are glad to have been given the opportunity of reading the letter from Mr. W. H. Withey. We had already read the paper by Mr. Withey and Miss Millar with much interest, and had spent a good deal of time in an attempt to interpret their results. These appeared to us to indicate that the material of their sheet No. 1 was free from both internal and superficial oxide; that rolling sheet 1 down from 0.01 to 0.006 in. in thickness produced a film thicker than that which we have so far found present on aluminium which has stood over long periods exposed to air, and that later rolling reduced the thickness of the film as well as that of the metal to a value much below the normal, assuming equal density of the films.
