1894. Report on a parasitic protozoan observed on fish in the 

 aquarium. Bulletin U. S. Fish Commission, vol. xin, 1893, 

 P. 173-190, pi. 11-12. 



Extended study of epidemic reported by S. A. Forbes (1894). Care- 

 ful description of parasite and of lesions produced by it. The form 

 is Ichthyophthirius mitltifiliis. The most practical method of destroying 

 the parasite is to attack it during the free stage period or subsequent 

 to encystment or during the enevsted stage, which lasts from one to 

 four clays. Salts in the bottom of the aquarium and a very weak solu- 

 tion of methylen blue and eosin gave good results. The reduction of 

 tin- temperature of the water was followed by a cessation of the 

 epidemic.

 for exterminating this species,
