 showed (1) that this bacillus could not be converted 

 into the hay bacillus (B. subtilis) ; (2) that the cultiva- 

 tions became gradually less active until they were quite 

 innocuous ; (3) that, when filaments were kept for a 

 time at a temperature which prevented the formation of 

 spores, the virulence became attenuated, and ultimately 

 disappeared." British Med. Journal, Nov. 4th, 1882. 



FATAL EPIDEMIC AMONG FISH CAUSED BY BAC- 

 TERIA. Dr. Ogle gives an account of an epidemic 

 among the perch in Lake Geneva, studied by Farel 

 and Du Plessis. The fish became sluggish, suffered 

 from a bilious diarrhoea, and the anterior part of 

 the head and body was injected with blood. The 

 intestines were distended with a transparent fluid 

 containing myriads of bacteria. The blood was 

 diffluent, and contained " bacteria and vibrios " 

 while the fish was still living. Experiments 

 proved that the disease was not communicable to 

 batrachia or to warm-blooded animals. 



Professor Huxley has given an interesting ac- 

 count of an infectious disease of the salmon, which 

 is apparently produced by a Saprolegnia identical 

 with that which infests the bodies of dead insects. 



GLANDERS. The discovery of the parasite of 

 glanders has recently been announced by Schutz 

 and Loeffler, who have pursued an experimental 

 investigation relating to the etiology of this infec- 

 tious disease of the horse, in Koch's laboratory in 

 Berlin. The parasite is said to be a bacillus re- 

 sembling that of tuberculosis. It is found in the
