phur. (/) Guadaloupe farcy ; virulentculturesof this peculiar affection 

 of the ox, obtained from Professor Nocard, were invariably rendered 

 inert after twenty-four hours' exposure to 60 grammes of sulphur, but 

 smaller proportions were uni-eliabie. To recapitulate, sulphur fumes 

 may be considered useless with septic vibrio and charbon. But in 60- 

 gramme doses to the cubic metre, and after twenty-four hours' contact, 

 they may be relied upon to destroy tuberculosis, glanders, farcy, typhoid 

 fever, diphtheria, and probably cholera germs. The germ of scarlet 

 fever remaining as yet unknown, no experiments could be instituted. 

 At the same time this instructive series of discriminating experiments 

 explains why some good authorities speak so highly of sulphur fumes 

 as an antiseptic, while other equally good authorities have pronounced 

 them nearly worthless. — Therapeutic Gazette. 



Simplified method for preparing Meat-Pepton-Agar. — Mr. N, 



Tischutkin prepares and filters meat-pepton-agar in the short time of 

 2-2^ hours. The requisite quantity of agar is placed for 15 minutes 

 in a dilute solution of acetic acid (5 ccm. acid acet. glacial in 100 ccm.). 

 The swollen agar is then carefully washed, free from acid, and then 

 mixed with bouillon. Boiling for 3-5 minutes suffices to make a perfect 

 solution of the agar in bouillon. After neutralizing and cooling down, 

 the whites of two eggs are added, and the mixture placed for half to 

 three-quarters of an hour in a Koch's steamer. It is next filtered 

 through Scliulze's paper. — Jour. Royal Micr. Society.

Methyl Blue Again. — Dr. H. Beyer, of Stapleton, N. Y., writes to 

 the Aledical News that he has used methyl blue in fifty cases of pha- 

 ryngeal diphtheria with successful results in all. He applies locally a 

 powder consisting of methyl blue 2 parts and sugar 98 parts. 



Milk from Tuberculous Cows. — Bang records some experiments 

 that tend to show that milk from tuberculous cows does not convey the 

 disease, unless the udder is tuberculous. Milk from tuberculous women 

 fed to rabbits did not infect them. Milk from cows with tuberculosis 

 of the udder proved highly intectious when fed to rabbits. Lesions 

 developed in the glands about the pharynx. — Centralblatt f. Chi- 

 ruj'gie., April, i8gi. 



Bacilli of Malignant Edema in Musk. — Several cases are on 

 record in which hypodermic injections of tincture of musk have been 

 followed by malignant edema and death. Recent experiments by Dr. 

 J. Van Cott, of the Berlin Hygienic Institute, show that the bacilli 

 come not from the musk itself, but from the animal's bag in which the 

 musk is contained. 



Adulteration of Musk. — In connection with the above item, it is 

 well to note a recent chemical and microscopical examination of a 

 sample of " pure Thibet musk," made by Th. Winimel, of Hamburg, 

 and recorded in the Apotheker Zeitu7tg. He found it adulterated with 

 starchy matter, vegetable cellular tissue, and water to the extent of more 

 than 25 per cent.
