Tuberculin and its use, A. E. de Scliweinitz (j)p. 159-178). — "The dan- 

 }?er of injecting tiibercnlin into healthy animals in moderate quantity- 

 is slight. In healthy guinea pigs I have found that an injection of a 

 (lose 20 times as large as that required to" produce a reaction in a 

 diseased cow may kill, but does not always do so." 



Examinations were made of samples of cow's milk (1) the day before 

 injection, (2) the day after injection when the temperature was about 

 ac the maximum, and (3) a day or two after injection, 



"In general the results show a decrease in total solids in the [milk of] tuhercnlous 

 animals after the injection. In the healthy animals there is also a slight decrease 

 in solids, but not as much as in the diseased animals. 



"There is also a decided variation in the proportion of fat before and after injec- 

 tion of the tuberculin as well as albuminoids and sugar. The fat and sugar decrease, 

 the albuminoids show a slight increase. The latter may, in part, be attributed to 

 the presence of a small amount of tuberculin in the milk. This variation in the 

 constituents of the milk would indicate that while under examination with tuber- 

 culin the milk of the animals should either not be used at all, or close attention 

 ])aid to the fact that tuberculin will cause such variations. These results are but 

 preliminary to a more extended examination." 



Bovine tuberculosis, A. T. Keale {Delaware Sta. Rpt. 1893, pp. 81- 

 10;2).— The condition of public sentiment and the prevalence of bovine 

 tuberculosis in the State are discussed at length. Ten herds, compris- 

 ing 3M cows, were examined by the station veterinarian. Of these 89 

 animals were condemned. A rise of 1.5° in the temperature of an 

 animal was sufficient for condemnation. The average expense for 

 tuberculin exceeded 50 cts. per head. "About 1 cow in every 10 thus 

 far killed and examined by this station for tuberculosis had a con- 

 sumptive udder." 



The method of disinfection followed by the station was to spray the 

 stables with a 1 per cent solution of chlorid of lime in a spraying pump 

 worked under a pressure of more than 100 lbs. to the square inch. 

 A small quantity of whitewash was added to the solution in order to 

 mark the thoroughness of the work. This solution " when driven 

 through the air by heavy pressure charges the barn so heavily with 

 chlorin gas that laborers are sorely tried while carrying out the work. 

 A barn thus sprayed and closed for a few hours must be regarded as 

 sterilized as thoroughly as circumstances will allow." Tabulated data 

 give the temperature records of the animals tested with tuberculin. 



Anthrax, A. T. Neale (Delaware Sta.Bpt. lS93,pp. 60-81). — This general discussion 

 of anthrax is largely a reprint of Bulletin 20 of the station (E. S. R., 5, p. 413). The 

 use of Pasteur's preventive vaccine for anthrax is discussed, and experiments in 

 which the use of vaccine failed to give immunity against the disease are briefly 

 described. The Delaware law relative to the reduction of infectious and coutagioua 

 diseases among the lower animals is given. 



Ringworm (Trichophyton tonsurans) in cattle, A. T. Neale {Delaware Sta. Bpt. 

 lS9S,pp. 50, 60), — An <jutbreak of ringworm, followed in several instances by death, 

 is noted. "Mercurial ointments, spirits of camphor, salicylic acid, and especially 

 tincture of iodin are recommended for local application." 



Texas or splenic fever, A. T. Neale ( Delaware Sta. Rpt. 1893, pp. 39-47). — A reprint 

 of Bulletin 23 of the station (E. S. R., 6, p. 81).
