Cutting and Mounting Microscopical Sections.* — Mr. A. G. 

 Bourne describes some modifications of older processes, which he 

 considers constitute the latest stage of development of the section- 

 cutter's art. 



Hardening. — Any of the ordinary hardening methods may be used, 

 but it is essential that all trace of acid should be removed in order to 

 obtain good staining results. Corrosive sublimate is an exceedingly 

 useful hardening reagent, and tissue treated with it stains as readily 

 as if treated with alcohol only. The solution used is a concentrated 

 one. The fresh tissue or living animal is placed in it for fifteen to 

 thirty minutes, according to its size ; it is then washed in water and 

 transferred to alcohol of 50 per cent. — a large relative bulk of this 

 must be used, and the tissue well permeated by it, otherwise some
