Dujardin-Beaumetz, one of the most eminent of French 

 physicians, that oysters should never be eaten by persons 

 with feeble dig^estive powers or those suffering from dila- 

 tation of the stomach. There is no article of food which 

 decomposes more readily in the stomach than does the 

 oyster, and none more likely to communicate infection 

 throug-h the setting- up of decomposition and fermenta- 

 tion in other foods. The oyster is always a carrier of 

 microbes, and recent observations show that it often com- 

 municates typhoid fever and other pathologfical g^erms.

Transmission of Tubercle. — Jaeckh iVirch. Archiv.) in- 

 vestigated the question whether the sexual glands or their 

 secretions contain virulent tubercle bacilli. He used the 

 testicles and the contents of the seminal vesicles, as well 

 as the ovaries of tuberculous patients who had died either 

 of chronic pulmonary tuberculosis or of genera miliary 

 tuberculosis. Portions of the sexual org-ans or of the 

 semen were introduced into the abdomen of g^uinea pig's 

 and rabbits. Of five cases in which portions of testicle or 

 of semen were injected, positive results were obtained 

 thrice with the semen and once with the testicular sub- 

 stance. All the rabbits remained healthy. Of three in- 

 jections with ovary one gave a positive result. Examina- 

 tion of the young tuberculous female guinea-pig-s g-ave only 

 one positive result. It appears, therefore, that the semen 

 may contain virulent tubercle bacilli, and that transmis- 

 sion of tubercle from mother to child is not the g^eneral 

 rule.

 that the cholera vibrio can penetrate the shells of hen's

Preservation of Blood for Examination. — H. Krai, che-
