Diseases in sheep, W. (t. Dowling (Aijr. '•'nz. Xev Suulh Wnhs, 14 {1903), No. 1, 

 pp. 15-17). — Strangury is reported as affecting as high as 20 jier cent of rams and 

 wethers in t'ertain flocks of sheep. The disease appears to be contagious and it is 

 suggested that flies may be instrumental in carrying the contagion. The treatment 

 for severe cases is of a surgical nature and consists in the opening of the sheath and 

 thorough treatment Avith antiseptic solutions. 



Pasteurellosis and strongylosis of sheep, .1. Lignikees {llec. MM. Vvt., 8. «er., 

 9 {1902), Xo. 22, pp. 669-679). — The author argues that pasteurellosis of sheep is due 

 to the attack of a species of Pasteurella and that the disease may occur in a chronic 

 form without the aid of an infestation by Strongylus. ( )n tlie other hand tlie i)resence 

 of these worms is favorable to the bacterial infection. 



The vaccination of Algerian sheep against sheep pox, l\. Nocakd {Tlcv. Vet. 

 Toulouse, 27 {1902), No. 11, pp. 7S1-7S7). — .\ controversial article in which the action 

 of the French Government in its attempts to check this disease is justified. 



Swine erysipelas serum, L. Deutscii {Cenlbl. Bakt. n. Far., 1. Abt., 3S {1903), 

 No. 3, Orig., pp. 214-229). — In the author's experiments the serum for preventive 

 inoculation against swine erysipelas was obtained from horses exclusively. The 

 bacillus which was used in producing the serum was tested and found to be capable 

 of producing death in pigeons when administered in doses of 1 cc. The virulence of 

 the bacillus Avas increased by 12 passages through pigeons, so that finally 1 cc. of cul- 

 ture proved to be fatal to pigeons Avithin from 36 to 42 hours. The author made a 

 number of observations upon the agglutinating action of the serum. It was found 

 that the agglutinating power is diminished by each injection of bacillus fori or 2 

 days, but gradually increases until from the eighth day on a more rapid increase in 

 the agglutinating i>ower takes place. When the agglutinating i^ower of the serum 

 unexpectedly undergoes a rapid diminution it is safe to conclude that the protective 

 power has also become suddenly diminished. In testing the protective power of 

 swine erysipelas serum the author considers it unsatisfactory to depend upon results 

 obtained from the inoculation of mice. Pigeons should be used for this purpose, 

 and the birds selected should be in good health and should weigh from 300 to 400 gm. 



The control of swine erysipelas, A. vax Leeuwen {Tijdschr. Yeeartsenijk. 

 Muandhlad, S9 {1902), No. 11, pp. 483-492). — A number of experiments were made 

 in testing methods for the control of this disease. As the result of his investigations 

 the author concludes that the virus of swine erysipelas is generally distributed 

 throughout the Netherlands and that preventive vaccination, so far from being 

 useful, is actually dangerous. The author believes that the disease may be com- 

 municated to healthy pigs by the use of the vaccine. Good disinfectants and 

 veterinary police measures are recommended in controlling the disease. 



Combating swine erysipelas, J. J. Wester {Tijdschr. Yeeartsenijk. Maandblad, 

 30 {1902), No. 2, pp. 49-63). — The author presents an elaborate discussion of the 

 means of controlling this disease, with special regard to vaccination. Vaccination 

 is said to be the most rapid method of diminishing the number of cases of swine 

 erysipelas. It is also believed that the danger of communicating the disease by 

 vaccination to live animals is exceedingly slight. The author urges the great value 

 of preventive vaccination as the general measure of control. The Netherlands, 

 however, are considered as lieing generally infected with the disease, and it is recog- 

 nized that the bacilli of swine erysipelas are regularly found in hogs in that country. 



Serum diagnosis in hog cholera and swine erysipelas, E. Ercol.\xi ( Gior. R. 

 Soc. Accad. Vd. Ml., 51 {1902), Nos. 27, pp. 690-693; 29, pp. 740-744)-— The author 

 studied the action of physical agents upon the agglutinating substances in blood 

 serum of animals affected with hog cholera. It Avas found that serum maintained at 

 a temperature of 50° C. for 2 successive days retained its agglutinating power with- 

 out any change. When serum Avas suddenly subjected to low temperatures, ita 

 agglutinating poAver Avas stronger than when subjected for a number of days to lugher 

 temperature. As a result of the author's studies upon these subjects it is concluded
