792 EXPEKIMENT STATION RECORD. 



which developed 8 weeks after calving and in which there were symptoms of mammitis, 

 potassium iodid infusions were not given. The udder was su])jected to friction, was 

 frequently immersed in hot water, and was relieved of its contents as often as possihle. 

 The cow recovered. 



Parturient apoplexy and its treatment, Witt (Berlin. Tierarztl. Wchvschr. 

 {1900), No. 22, j)p. 253, 254). — The author treated 57 cases of this disease by means 

 of infusions of potassium iodid with recovery in 50 cases after from 6 to 12 hours. 

 The author takes issue with Schmidt in his theory of the nature of the disease and 

 the effect of the potassium iodid treatment. The author noted a relatively lax and 

 soft condition of the udder in 80 per cent of the cows which were treated and a 

 complete or nearly complete cessation of milk secretion in every case. It is believed, 

 therefore, that the cerebral anemia observed in many cases of parturient apoplexy is 

 not due to any increased blood pressure in the udder. The action of potassium iodid 

 infusion has been exj^lained as checking the secretion of milk. The author maintains, 

 on the contrary, that whenever milk secretion is partly checked soon after calving 

 parturient apoplexy is likely to be developed, and that the treatment of the disease 

 consists in stimulating the udder to its customary secretory activity. The author 

 believes that in ordinary cases recovery takes place very rapidly after milk secretion 

 is resumed. 



Is a post-mortem examination necessary in the diagnosis of anthrax, 

 Steixbach (Berli)i. Tkmrztl. Wclinschr., 1900, No. 41, ])p. 481, ^(S'-^).— According to 

 the author's experience, a post-mortem examination is necessary in suspected cases of 

 anthrax in which a microscopic examination of the blood failed to give a positive 

 diagnosis. 



Dehorning {Agr. Jour. Cape Good Hope, 17 {1900), No. 7, j^P- 387-390).— A brieli 

 account of this operation, taken in part from the Sydney Telegraph. 



Three important diseases affecting sheep, J. D. Stewart {Agr. Gaz. New 

 South Wales, 11 {1900), No. 10, pp. 837-S4G). — Notes on stomach worms, lung worms, 

 fluke worms, and foot rot. The author recommends the most approved remedies 

 for the treatment of each of these diseases. 



Etiology of louping ill, J. McFadyean {Jour. Comp. Path, and Ther., 13 {1900), 

 No. 2, pp. 145-154). — The author gives a general historical account of this disease. 

 The name louping ill has apparently been applied to a number of distinct diseases, 

 such as pya^mic spinal meningitis, gastritis, enteritis, and disorders of brain func- 

 tions. The relationship of grass ticks to louping ill is believed by the author to be 

 a problematical question. The author concludes that the etiology and pathology of 

 the disease are still obscure and that the whole subject needs a careful investigation. 



Periodical ophthalmia of the horse, L. Bernhard {Berlin. Tierarztl. Wchnschr., 

 1900, No. 26, pp. 301-304). — Detailed notes on the symptoms of the disease, together 

 with an account of its prevalence. 



Malignant oedema in horses, S. v. Ratz {Monatsh. Frakt. Thierh., 11 {1900), 

 No. 9, pp. 411-416). — Detailed reports are given on the clinical symptoms and post- 

 mortem findings of 2 cases of this disease in horses. The bacilli were strikingly 

 similar to those of blackleg. White mice inoculated with oedematous material died 

 2 days later. 



The pathogenic organism of horse sickness, Rickmann {Berlin. Tierarztl. 

 Wchmclir., 1900, No. 27, pp. 314-316, fig. i) .— It was found by experiment that if 

 virulent blood from a case of this disease was passed through a Chamberlain filter it 

 ceased to be virulent. A microscopic examination of such blood revealed the pres- 

 ence of micro-organisms similar to those of malaria. 



The horses of South Africa and their most important diseases, especially 

 malaria, ZUrx {Zt-schr. Tiermed., 4 {1900), No. 2-3, pp. 14^^-163).— The author gives 

 a description of the tsetse fly {Glossina mor.ntan,^) and discusses its agency in the 

 transmission of malaria to horses. A number of species of flies of the same genus
