Summary.1 The cell‐wall of the living cotton‐hair is under tension and its diameter is unaffected by osmotic pressure or the death of the cell. 2 Increase of diameter of the uncollapsed hair by swelling in caustic soda varies inversely as the diameter of the hair in the case of fine cottons, and does not occur with coarse cottons. 3 The diameter of the uncollapsed cotton‐hair varies inversely as the intrinsic strength of the collapsed hair.I have to thank Dr R. H. Pickard, F.R.S., and his colleagues Miss Calvert, M.Sc, and Miss Clegg, M.Sc, of the Shirley Institute, Manchester, for their very helpful criticisms.
