588 EXPERIMENT STATIOX RECORD. 



Scliiitz's streptococcus is the etiological factor this organism must for the 

 present be presumed to be the cause of equine influenza. 



Hemog-lobinuria of horses and its treatment, Drouin (Rev. Gen. MM. 

 Vdt., 11 {1911), No. 200, vp. U9-468; abs. in Berlin. Tierdrztl. Wcluhschr., 27 

 {1911), No. 3S, pp. 693, 69^).— A detailed statement of the treatment for this

Carbon bisulphid for ascarids in the horse, D. Gkoag {AlJatorvosi Lapok, 

 33 {1910), No. 15, p. 112; ahs. in Berlin. TirrdrzU. Wchnsehr.. 21 (1911), 

 No. 16, p. 292). — After placing gelatin or Iceratin capsules containing the car- 

 i)on bisulphid upon the tongue of the hors^e an assistant pours water from a 

 bottle into the mouth of the animal In about 36 houi's the ascarids are ex- 

 pelled. The author, however, recommends giving evacuants, such as aloes 

 and castor oil. In order to be certain that the ascarids are expelled. 10 gm. 

 of carbon bisulphid is given in the same manner some weeks latter. 



The viability of parasitic ova in two per cent formalin, with especial ref- 

 erence to Ascaris lumbricoides, R. S. Morbis (BuI. Johns Hoplcinn Hosp., 22 

 {1911), No. 2Jt6, pp. 299, 300). — The author has found that the ova of A. lum- 

 bricoides may remain viable in a 2 per cent solution of formalin for an indefi- 

 nite period. In the observations reported the embryos were still motile 29 

 months after they were first observed to be alive. A few embryos which had 

 escaped from the shell were observed, but in all instances they were dead. 



Spirochetes and hemorrhagic gastro-intestinal infections of the dog, V. 

 Ball and Roquet {Jour. MM. V^t. et Zootech., 62 {1911), May, pp. 251-260, 

 flg. 1; abs. Vet. Rec, 2Jf {1911), No. 1211, pp. 219, 280).— The spirochete con- 

 cerned, which has previously been reported by Regaud °' as commonly present 

 in the normal gastric mucous membrane of the dog and cat, is described as 

 Spirochwta regaudi. The authors' investigations of the dog indicate that this 

 organism is not the cause of hemorrhagic gastro-enteritis. The spirochetes 

 were commonly found in the mucous membrane and are as frequent in normal 

 stomachs as in those showing inflammatoiy and hemorrhagic lesions. 



A microfilaria from the domestic fowl, Beeke {Centbl. Bakt. [e^c], 1. Abt., 

 Orig., 58 {1911), No. 4, pp. 326-330. pi. 1; abs. in Jour. Roy. Micros. 8oo., 

 1911, No. 5, p. 625). — ^The author describes a microfilaria that was found to be 

 very abundant in the liver of a domestic fowl in Kamerun. 



Coccidiosis in British game birds and poultry, H. B. Fantham {Jour. 

 Bcon. Biol., 6 {1911), No. S, pp. 15-96, figs. 2). — This paper deals with the oc- 

 currence of Eimcria avium in the host, the symptoms of coccidiosis in birds, 

 the life history of E. avium, as previously noted (E. S. R., 24. p. 684), notes 

 on the condition of the internal organs of infected birds, the dissemination of 

 coccidiosis, duration of vitality of coccidian oocysts, some preventive measures 

 and suggestions for treatment, and some other coccidia and their hosts. 



Blackhead.— Infectious entero-hepatitis or typhlo-hepatitis. — A disease of 

 young turkeys, W. Jowett {Jour. Oompar. Path, and Ther., 2', {1911), No. 4, 

 pp. 289-302, figs. 14). — This paper, which records the occurrence of this disease 

 in Cape Town and the Western Province, has been previously noted from an- 

 other source (E. S. R.. 26. p. 384).

 XVI+339, figs. 60).^This edition represents an entire rewriting of this work 

 on the basis of additional data which has become available since the prepara-
