From these localities will be found several genera, for 

 splendid specimens of which English microscopists are in- 

 debted to a few feUow-labourers in America, but more 

 especially to Professor Bailey, of West Point. 



Many other kinds of infusoria may be preserved as micro- 

 scopic objects, whose bodies are either soft or contain only a 

 small trace of silica; they may be mounted in one of the 

 preservative fluids before described at page 278, but of these 

 the Glycerine appears to preserve the colour best, although 

 the fluids recommended by Mr. Thwaites and Mr. Ralfs wiU 

 answer for most purposes. The cell to be employed should 

 be very thin, either made of the finest glass or of gold-size,
