THE second volume of Thorpe's “Dictionary” has made its appearance with commendable punctuality. In a foreword, the editors state that they have done their utmost to reduce the space occupied by organic formulae, although they maintain, quite rightly, that a modern article on organic chemistry must be illustrated by elaborate formulae. How much more, however, should an article on an industrial process be illustrated by elaborate drawings of plant ? Yet these are mainly conspicuous by their scarcity. The new special drawings promised in the foreword appear to be about eleven in number and, of these, eight are small and purely diagrammatic. A cement kiln is allotted far less space than the six formulae for cedrene and its derivatives, and many of the photographs give no useful information. The outstanding exception is the article on bromine, with ten good drawings reproduced from the Supplement.
