Bee, 23 (1911), No. 1183, t). 579). — A new ovine disease is described, and ex- 

 periments reported. 



The disease usnally first manifests itself in the newly lambed ewes, then in 

 the newly born lambs, and finally spreads to other lambs and sheep. The 

 etiological factor is supposed to be a diplococcus simulating an atypical form of 

 the Diplococcus pncumonicE, and which was isolated from the blood and 

 organs of sheep dead from the disease. The organism was capable of repro- 

 ducing the disease by introduction into the respiratory tract, the alimentary 

 tract, and the peritoneum. The name proposed by the author is Streptococcus 

 (Diplococcus) Idnceolatus ovium. 



Symptomatically considered, the ewes became sick and showed a fever cor- 

 responding to a temperature from 103.8 to 105.4° F., a loss of appetite, general 

 prostration, and a distended, tender abdomen. " The mucous membranes of 

 the vagina and vulva were swollen and reddened, and a foul-smelling fluid was 

 discharged from the genital passages with the accompaniment of painful 

 straining." Another form manifests itself by a profuse, purulent, nasal dis- 

 charge, which is accompanied by a swelling and tenderness in the nares and 

 associated with fever and prostration. Three different forms could be noted 

 on post-mortem examination. 



Eeport of the veterinary department, R. A. Craig (Indiana St a. Rpt. 1910, 

 p. 61). — During the year ended June 30, 1910, more than 400.000 cc. of hog- 

 cholera serum was produced. The total number of hogs treated was about 

 10,000. Reports of 2,116 hogs treated in 42 herds show 70, or 3.3 per cent, to 

 have died. The average cost to stockmen of the average dose of serum used 

 (40 cc.) was 60 cts. per hog. 



" For the purpose of increasing the quantity of virulent material that may be 

 secured from a virulent blood hog, from 1,500 to 3.000 cc. of a normal salt solution 

 was injected into the abdominal cavities of a number of the hogs used in this 

 work. The injections were made 2 hours before the cholera hogs were bled, and 

 as soon as the animals had died the virulent normal salt solution was removed. 

 Eleven hyperimmunes were produced with the virulent normal salt solution, and 

 all of them produced potent serum." 



Epizootic of mastitis in pig's, A. V. Toth (Berlin Tierdrstl. Wchnschr., 27 

 (1911), No. J/, pp. 58, 59). — It has been observed that in many instances the 

 mammary gland of the female hog becomes infected and destroyed, and even- 

 tually drops off. The author seeks to show the relation which variola and 

 pasturing have to the disease. He found a few bacteria in the nodules which 

 were present in the gland, and will report upon their identity later. 



The surg'ical anatomy of the horse, J. T. Share- Jones (London, 1906, pt. 1. 

 pp. XII +159, pJs. 33; 1907, pt. 2, pp. X-VWO, pis. 3',; 1908, pt. 3, pp. X + 

 220, pis. 28). — Part 1 of this work is devoted to the head and neck, part 2 to 

 the fore limbs, and part 3 to the hind limbs. 



A protective reaction of the host in intestinal coccidiosis of the rabbit, 

 T. Smith (Jo'tir. Med. Research, 23 (1910), No. 3, pp. J,07-J,15, pis. .i).— The 

 author here reports studies made of Eimeria stiedxc (Coccidiuni cuniculi) in a 

 rabbit, which indicate the manner in which immunity establishes itself. 



The morphology and life history of Eimeria (Coccidium) avium, a sporo- 

 zoon causing a fatal disease among young grouse, H. B. Fantham (Proc. 

 Zool. Soc. London, 1910, III, pp. 672-691, pis. '/, dgin. 1 ) .—The complete life cycle of 

 E. avium, responsible for the dwindling of grouse broods in the spring, is here 

 set forth for the first time. It is shown that, owing to the rule of priority, the 

 generic name Coccidium (Leuckart, 1879) no longer holds, being replaced by 

 that of Eimeria (A. Schneider, 1875). Since the coccidia of birds were first
