Elementary Microscopical Manipulation. By T. Charters White, F.R.M.S. (Roper and

Trowley.)—Mr. White gives, in about a hun- dred pages, much sound advice as to the manipulation and mounting of microscopical objects, histological and otherwise. Many similar manuals exist, nor was there any absolute necessity for publishing a new one ; yet, as each investigator has a particular method of mounting his preparations, a larger selection is afforded the student to choose from, and this he is not likely to despise. Additions to the already extensive literature of microscopy have thus always an in- terest to an observant student, because he may glean some method suited par excellence to his means or accommodation. He will find most of what he needs in the present volume.
