482 EXPERIMENT STATION EECORD. 



"Cattle of any age and either sex may be infected by natural channels with 

 the bacillus of epizootic abortion. Male animals (bulls and steers) can be 

 infected by way of the prepuce. 



" The agglutination and complement tests when applied to the serum of ani- 

 mals experimentally infected yield results that are broadly concordant. Either 

 of these tests may give positive results within from 7 to 21 days after infection. 

 In animals in which the result of the agglutination test is negative 3 weeks 

 after the attempt to infect, it generally remains negative, and indicates that the 

 animal has not become infected." 



Myiasis in cattle in West Africa caused by Chrysomyia (Pycnosoma) 

 megacephala, G. Bouet and E. Roubaud {Bui. Soc. Path. Exot., 5 (1912), 

 No. 9, pp. 737-739; ais. m Trop. Vet. Bui., 1 {1913), No. S, pp. 182, 183).— A 

 report of a case of myiasis in a cow caused by this dipteron, a species which 

 appears to be widely distributed in Africa. 



[Paralysis of lambs apparently caused by Dermacentor venustus], F. Tob- 

 KANCE {Amer. Vet. Rev., JfS {1913), No. 3, pp. 811, 3/2).— Studies by S. Hadwen 

 of the paralysis of sheep and especially of lambs, which has caused losses from 

 time to time in British Columbia, indicate that D. venustus may be a causative 

 agent. A lamb to which these ticks were experimentally attached along the 

 spine showed signs of lack of coordination on the sixth day and a total loss of 

 coordination on the seventh, which condition progressed until on the tenth day 

 the lamb was paralyzed. 



The occurrence and forms of Piroplasma ovis in Dalmatia, H. Inchiostri 

 {Osterr. Wchnschr. Tierheilk.. 37 {1912), Nos. 29, pp. 289-292: 30, pp. 299-302; 

 31, pp. 310-313; 32, pp. 320-322; S3, pp. 331, 332; 3J,, pp. 340-3J,3; abs. in Trop. 

 Vet. Bui., 1 {1912), No. 1, pp. 7-9; Rev. G6n. M6d. V6t., 21 {1913), No. 242, 

 pp. 68-71). — The author describes peracute, acute, ephemeral or abortive, 

 chronic, and latent forms of ovine piroplasmosis which occur in the vicinity of 

 Zara. Rhipicephalus bursa is said to be the tick that occurs on sheep in this 

 district. 



Epizootic of hog' cholera (with the presence of Salmonella) at Algiers. 

 Experimental transmission by the filterable virus, E. Sb:bgent, A. Lh^kitieb, 

 A. BoQUET, and P. Denarnaud {Bui. Sac. Path. Exot., 5 {1912), No. 10, pp. 781- 

 784)- — A report of studies made during an outbreak of hog cholera at Algiers. 



The relation which the Bacillus voldag'sen has to hog' cholera, W. Pfeilee 

 and A. Kohlstock {Berlin. Tierdrztl. Wchnschr., 29 {1913), No. 12, pp. 209- 

 211). — A criticism of Haendel and Gildemeister's findings (E. S. R., 28, p. 183). 

 See also other notes (E. S. R., 24. p. 390; 26, p. 785; 28, p. 183). 



Method of using antihog cholera serum, D. E. Baughman {Amer. Vet. Rev. 

 IfS {1913), No. 2, pp. 145-150). — This details a number of cardinal principles to 

 be observed when vaccinating against cholera in hogs. 



The viability of certain cysticerci in pigs and in young dogs, J. W. Scott 

 {Science, n. ser., 37 {1913), No. 946, p. 263). — In experiments conducted by the 

 author to determine whether hogs are injured by feeding upon rabbits infested 

 with cysticerci of Tinea serrata and T. serialis, negative results were obtained in 

 that no tapeworms were found when the hogs were slaughtered 10 days later. 

 It is stated that when com is scarce it is a common practice for farmers in 

 western Kansas to feed hogs on jack rabbits in place of corn. 



When the cysticerci were fed to young dogs from 90 to 100 per cent were 

 recovered as young tapeworms. 



Protective vaccination against the pectoral form of equine influenza, 

 GoBLiTz {Abs. in Berlin. Tieriirztl. Wchnschr., 28 {1912), No. 52, pp. 986, 087).— 

 Pfeiler's method, which consists of the intravenous injection of serum and vac- 

 cine, was used. Diseased animals received 100 cc. of serum as cui-ative treat-
