For mounting the smaller species, a thin layer of gum is placed 
upon the divisions. The specimens are picked out with a small brush 
moistened with water, and applied to the gummed surface.

Technique of Microscopical Anatomy, f — MM. A. B. Lee and L. F. 
Henneguy have just issued the second edition of a treatise on the 
technical methods of microscopical anatomy. The present volume 
has been entirely recast and considerably enlarged. This work is the 
outcome of the ‘ Mierotomist’s Vade-Mecum,’ a handbook of the methods 
of microscopic anatomy, published in London in 1885, and differs 
therefrom chiefly in amplifications in one direction and suppressions in 
the other. Many old methods have been omitted and replaced by newer 
ones, and many new features have been added. The additions are chiefly 
connected with staining, especially with carminic acid, haematein, and 
anilin pigments. The chapter on cytological methods has been entirely 
recast, and those on the nervous system considerably amplified. Among 
the suppressed portions is the chapter on bacteriology, so that the 
present work appeals chiefly to histologists, embryologists, and zoologists. 
The treatise is divided into two parts, the first comprising general 
methods, while the second is devoted to special embryological and 
histological procedures. 
The character, utility, and excellence of the previous edition are so 
well known that it is almost superfluous to say that in the present 
volume the high standard is maintained.
