By Sir M. FOSTER, K.C.B., M.D., D.C.L. Demy 8vo.

Physiologists therefore owe a debt of gratitude to Sir Michael Foster for supplying a want which was widely felt.... No higher praise can be given to the book than to say that it is worthy of the reputation of its author. +The Soluble Ferments and Fermentation.+ By J.
