524 EXPERIMENT STATION RECORD. 



bouillon in sterilized flasks was inoculated with a culture of the tuber- 

 cle bacillus and kept at 38 to 39° C. for G to 8 weeks. The culture 

 flasks were then heated at 70° C. for 3 hours, the contents filtered, and 

 the filtrate evaporated at 00° to one-tenth the original amount. This 

 preparation was tried on cows with satisfactory results, but the effect 

 on guinea pigs was not so encouraging. 



The milk of a tuberculous cow, with no external evidences of any 

 tuberculous lesion of the udder, was fed to guinea pigs in the form of 

 scum from the separator bowl, mixed milk and cream, whole milk, and 

 whole milk sterilized 1 hour, from November 7, 1893, to January 2, 1894, 

 with negative results. 



In an examination of about 30 samples of milk for tubercle bacilli 

 the results were negative, except in one case, and the author says, 

 "The simple apparent detection of tubercle bacilli [in the absence of a 

 biological examination] is not sufficient ground for condemning a milk 

 sample." 



In an examination of nodular cheesy matter from the lung of a cow 

 no tubercle bacilli were found, but a guinea pig died of general tuber- 

 culosis from an abdominal injection of this cheesy deposit. 



Weights of cultures of tubercle bacillus, C. L. Penny {Belaware 

 8ta. Bpt. 1895, p. 207). — The author separated and weighed the bacilli 

 in 13 cultures made in the preparation of Koch's tuberculin. The sep- 

 aration was made by means of Gooch crucibles i^acked with asbestus. 

 The cultures had been made in 50 cc. glycerin bouillon and the weights 

 obtained ranged from 0.1502 to 0.2806 gm., with an average of 

 0.1939 gm. 



On the toxic properties of molds, R. R. Dinwiddie {Arl-ansas 

 Sta. Bui. 40, pp. 35, 36). — A 2-year-old colt was fed for 3 weeks 

 about 12 ears a day of badly molded and worm-eaten corn along with 

 hay. From January 3 to March 1 artificial cultures of molds on bran, 

 mixed with dry bran were fed with good hay. No harmful results were 

 observed. A second colt, after having eaten moldy corn for 6 Aveeks, 

 was fed jjure cultures of Fenicillum glaucum for 5 weeks with no apparent 

 ill effects.

Bacteriological -work upon anthrax, F. D. Chester {Delaware Sta. Mpt.lS95,pp. 

 64-9S). — The writer discusses the bacillus and its detection, the vitality of the anthrax 

 organism, the jjroper disposal of anthrax carcasses, and the preparation of atten- 

 uated virus at the station. Under the last head are given in detail the experimental 

 tests of the virus.
