important agent in histological and bacteriological tech- 

 nique ; and its remarkable powers of penetration, its ef- 

 fectiveness and ease of application in solution, spray and 

 vapor and its apparent harmlessness to tissues and fa- 

 brics in the quantities necessary to destroy bacteria, all 

 combine to make it a valuable vermicide.

In the Stephoidea there were 11 genera ; in the Spyroi- 

 dea 25 genera ; in the Botryodea 5 genera ; now we come 

 to a sub-order in which there are 79 genera or almost 

 twice as many as in all the other three sub-orders put to- 

 gether. This sub-order alone of the Legion NASELLA- 

 RIA, or MONOPYL^A more than equals tlie whole 



of the legion SPUMELLARIA, or PERIPYLiEA in the 

 number of its genera. Fortunately, however, it has four 

 well marked sections, characterized by the number of the 

 joints, and the distinction, MOUTH OPEN, or mouth closed, 

 which runs all through the sections, is also a great help 

 in the determination of these forms.
