How to Work with the Microscope. By Lioner S. Bzraxz, 
M.B., F.R.S. Third Edition. London: Harrison. 
Tuere are few persons to whom modern microscopic re- 
search is more indebted than to Dr. Lionel Beale. It is to 
his. pen that we owe a larger series of works on the struc- 
ture and uses of the microscope than to any other living 
man. One of his earliest and most useful works was ‘ The 
Use of the Microscope in Practical Medicine,’ which may be 
said to be the manual by which the medical student more 
especially works. In addition to this general contribution to 
the literature of his profession, we have from his pen writings 
devoted to more special subjects. Thus, im his work on 
‘Urine and Urinary Deposits,’ he has given, not only the 
general results of microscopic observations on urinary depo- 
sits, but has added a large number of observations of his own. 
The nature of these deposits he has illustrated by a series of 
‘Jllustrations of Urine, Urinary Deposits, and Calculi,’ pub- 
lished in a separate form. In his ‘ Archives of Medicine’ he 
has contributed a series of papers showing how thoroughly he 
understands the practical application of the microscope to the 
elucidation of the nature of disease. His contributions to the 
‘Philosophical Transactions,’ and his papers in our own pages 
on the structure and formation of nervous centres, and the 
ultimate conditions of cell-formation, stamp him as one of the 
most sagacious observers and original thinkers of the modern 
European school—as one amongst the few British micro- 
scopists who may take a place by the side of Kélliker, Schwann, 
Schultze, Schleiden, and the great school of German micro- 
scopic observers. For this reason he has been worthily se- 
lected as the editor of the late Dr. Todd’s ‘ Clinical Lectures,’ 
and also as the colleague of Mr. Bowman in the production 
of a new edition of Todd and Bowman’s ‘ Physiological Ana- 
tomy.’ To have such a man for a guide is the privilege of
