I t may seem that this volume stresses tools and methods of physics but colloid chemists need to consider the possibilities of such tools in their own field.Īlexander and his numerous associates deserve high praise for putting into a single large volume a small library of invaluable and stimulating information, Scientists in all fields will profit by reading it. Notably the concentration of fish liver oils for the vitamin A market. Hickman records the development of his molecular still and its present uses. The chapter by XfarInnes and 1.ongworth on Elccrrophorctic Study of Protein, is esperially rlpar and hrll,- ful. Clarke con- siders the more recent Tswett column work as an extension of this diffusion ring study. Komik Legenda Naga.īeverly Clarke points out that Goppelsroder began his work with spot tests (diffusion rings) as early as 1861. In such great dilution as 1: 10,000,000 i t shows an appreciable effect on capillary permeability. He describes in detail his preparation of leukotaxine and its properties. He compares the conflicting theories as to the role of histamine and leukotaxine and pronounces in favor of the latter as the effective agent in increase of capillary permeability.
