 preface on ' Graham and other Atomists ' (pp. 17). The excellent analytical Index greatly facilitates the use of the great 

 mass of papers here collected together. 



' As a chemist Graham held ideas far in advance of his contemporaries. Before 1840 he had discovered and proved the 

 polybasic character of phosphoric acid, proving that this acid forms several distinct compounds with water. He even 

 laid down the bold theory that all the (so-called) elements may be only forms of one primordial one.' D. N. B.

' His admirable text-book, Elements of Chemistry . . . Graham's originality was shown by his valuable physico-chemical 



investigations on the diffusion of gases, osmose, etc., which opened out new paths in the science, while at the same tin:e 



he enriched general chemistry, especially inorganic, by his purely chemical work.' Prof. E. v. Meyer.
