(London, Richard Taylor and William Francis, 1854). 4to. No wrappers as extracted from "Philosophical Transactions" 1854, Vol. 144 - Part I. Pp. 177-228, 3 fine textillustrations in woodcut. Clean and fine.

First appearance of this importent paper in which Graham coins the word "dialysis" denoting the passage by diffusion of dissolved substances as a function of their concentration and molecular mass. In this way he further explained 'exomosis'.

"Thomas Graham (1805-1869) studies diffusion in gases and solutions and discovers and names the phenomenon now known as the osmotic force. He finds that certain substances (i.e. glue) pass more slowly through membranes than others (i.e. common salt). He calls the former colloids and the latter crystalloids and introduces the notion of dialysis to describe these observations. The beginning of his famous lecture "On osmotic force" with illustrations is shown on the right."(From Anders Gedeon "Science and Technology in Medicine", p. 244, where part of the first page and the illustrations from the offered paper, are shown).
