Black Death. — Ketasalo has ascertained that the "black- 

 death " amongst animals in Hong- Kong- is due to a bacillus 

 which causes a septecaemia attacking- the lymphatic sys- 

 tem, the spleen, and it might therefore easily be mistaken 

 with anthrax in animals. The bacillus is rounded at the 

 ends, colors with the usual aniline dyes, more deeply 

 stains at the end than in the middle. The org-anism may 

 be found in the Ijlood. The org-anism occurs in man, mice, 

 rats, swine, and the spread of the disease in China is to be 

 accounted for solely on the filthy habits of the Chinese. 

 Clothes are not chang-ed or washed for years. Chinese 

 frequently herd together with their swine. The disease 

 may be contracted by eating diseased meat. (Veterinary 

 Journal, XLII, 311. )
