VETERINARY SCIENCE AND PRACTICE. 895 



Four pigs and 15 calves were fed milk from the tuberculous cows; the 



pigs being given some meal and the calves a little hay in addition. The 

 pigs were killed when they weighed about 175 pounds, and the calves 

 when from G to S weeks old. One of the pigs and 2 of the calves were 

 found to be tuberculous. 



Parturient apoplexy and its modern methods of treatment, 

 Poeppel {Milch Ztg., 27 (1898) No. 40, pp. 628, 629).— In this article, 

 which is a reprint from another journal, the author summarizes the 

 opinions regarding causes and treatment of parturient apoplexy 

 {Eclampsia puerperalis) in milch cows and reports results of recent 

 investigations. According to a Danish veterinarian, Schmidt von 

 Kolding, the disease is caused by decomposition of the secreting cells 

 in the udder when the milk secretion begins after calving, a leukomaiue 

 being formed from the cholesterin bodies, this leukomaiue being the 

 direct cause of the disease. The method of treatment proposed is 

 injection into the udder of a solution of 10 gin. of potassium iodid in 

 a liter of freshly boiled water. The solution should be inserted at a 

 temperature of 40 to 42° C. A milk catheter with a wide canal attached 

 to a funnel by means of a rubber tube may be used. Instruments 

 should be disinfected. If complications due to the effect of potassium 

 iodid on the heart are feared, sodium iodid maybe used in its place. 

 It is stated that 02 per cent of the cows treated by this method recov- 

 ered. The percentage of recovery by the usual methods of treatment 

 was 50 to GO. 



Life history of the sheep-scab mite (Psoroptes communis), C. P. 

 Gillette {Ganad. Ent., 31 (1899), No. l,p. 9). — In order to ascertain 

 how long a time should intervene between the first and second dippings 

 of sheep for the cure of scab, the author undertook to determine the 

 period of incubation and also the time elapsing from the deposition of 

 the egg to the time that the mite from that egg, if a female, may itself 

 deposit eggs. It was ascertained that it requires 4 days for a newly 

 deposited egg to hatch and the entire time elapsing from egg to egg 

 would be about 14 or 15 days. As there would be eggs in all stages of 

 incubation upon a sheep when the latter is dipped for the cure of scab, 

 the author states that a second dipping should follow not sooner than 

 5 nor later than 10 days after the first dipping. 



Tuberculosis of cattle. B. Bam; | Pennsylvania Dept. Agr. Bpt. 1897, pp. 4SO-494). — 



A general article. The topics covered are the desirability of freeing herds from tuber- 

 culosis: infection of cattle stabled and herded together; value of sanitary condi- 

 tions; infection of swine, calves, and other animals, and man by the use of milk of 

 tuberculous cows; accuracy of the tuberculin test; success of measures against 

 tuberculosis in Denmark; and the advantages of suppressing bovine tuberculosis. 



Tuberculosis, W. SAUNDERS I Canada Expt. Farms 1,'jit. 1897, />}>■ 70-75). — A detailed 

 report is given of the results of a tuberculin test at the central farm. 



Brief notes are also given of testing the herds at the experimental farms at llran- 

 dou, Indian Head, and Agassiz.
