Caseous Rhinitis. — During- the last year or two Prof. 

 Guarnaccia (Archivii Italiani di Laring-olog-ia, No. 4, 1896) 

 has made bacteriological researches upon caseous rhinitis. 

 These studies refer to a case observed by Massei in his 

 clinic. Guarnaccia has demonstrated that the micro- 

 org-anism found in rhinitis caseosa, which was so differ- 

 ently understood by Perier, Sabrazes, etc., is streptothrix 

 alba, or Foersterii, studied by Rossi-Doria, Cohn, and 

 Gasperini. The author was able to cultivate it in ag-ar 

 g-elatin, bouillon, blood-serum, potatoes, and milk. Inocu- 

 lations in animals were not successful. It is perfectly 

 correct, in his opinion, to assume that the considerable 

 amount of caseous matter is formed by the g-rowth of the 

 streptothrix, as is the case in mug-uet. — Universal Medi- 

 cal Journal. 



Tuberculosis in Goats. — From the following- it will be 

 seen that the hitherto accepted theory that g-oats are 

 immune to tuberculosis is not altog-ether correct. Bulling- 

 (Indian Medical Record) records a case of pulmonary 

 tuberculosis in a g-oat. Both lung-s were adherent, and 

 larg-e and small tuberculous foci were present. The 

 author concludes that it would be well to examine into the 

 possibility of the transmission of tuberculosis throug-h the 

 ag-ency of g-oats, and to consume their milk only after boil- 

 ing-, or after the g-oat has been shown to be free from 

 tuberculosis by the absence of reaction after the injection 

 of tuberculin.

Circulation of Blood. — Most books recommend the use 

 of a frog-'s foot for this purpose and give directions for 

 accomplishing- the purpose. The object may easily be 

 attained with a small tadpole, lizzard, and with many of 

 the larg-er water larvae. The latter will show the circu- 

 lation all throug-h the body. With the lizzard and tadpole, 

 it may best be seen in the thin membranes of their tails. 

 All that is necessary is to place the animal in a glass slip 

 with a shallow cell and cover it.
