In the article on “Diffusion in a Fluid Moving a t Uniform Velocity in a Tube” [A. Klinkenberg, H. J. Krajenbrink, and H. A. Lauwerier, IND.ENG.CHEM.,45, 1202 (1953)], the subcaption of Figure 1 should be:
Figure 16. Plastic Effect
features described in this paper have been found in all, and roughly to the same extent. This does not necessarily mean that no correlation exists, but that, if i t does, its detection would require a much more extensive and quantitative study than was involved in the present work. LITERATURE CITED
