effective, simple, inoffensive, rapid, and economical. A generator v^^hich they 

 have had constructed is described and a claim of originality made for the pro- 

 cedure and its application in the treatment of mange in the horse, all the specific 

 clinical signs of which disappear within a few days after treatment. The results 

 obtained in the treatment of nine horses with ring\vorm are said to have been 

 satisfactory. The lice and nits are radically destroyed without any recurrence 

 by a sulphuration of 25 minutes. 



Auto-inoculation and early development of the larva of the horse botfly in 

 the buccal mucous m.embrane, E. Roubaud {Compt. Rend. Acad. Sci. [Paris], 

 164 (1917), No. 11, pp. 453-456; abs. in Internat. Inst. Agr. [Rome], Internat. 

 Rev. Sci. and Pract. Agr., 8 (1917), No. 5, pp. 757, 758). — In experimenting with 

 the guinea pig the author has found that the egg of the horse botfly (Gastro- 

 philus iiitestinalis DeGeer) does not hatch spontaneously but that the larva may 

 remain for several weeks awaiting the mechanical contact by which hatching is 

 brought about. The larvae which are liberated at once by mechanical contact — 

 the mucous membrane of the tongue is not indispensable, since sharp rubbing 

 against the animal's teeth or gums has the same effect — never perforate the 

 epidermis but bury themselves in the epithelium and develop in the mucous 

 membrane of the mouth. In the guinea pig the larva was observed to penetrate 

 beneath the epithelium parallel to the surface and remain in a superficial posi- 

 tion. One individual observed in the mucosa of the tongue had tripled in size by 

 the ninth day. After the first molt the larvie pass to the stomach. 



Contribution to the study of epizootic lymphangitis, Teuche and Guignakd 

 (Bui. Soc. Cent. Med. Vet., 93 (1917), No. 3-4, pp. 64-68; abs. in Vet. Rec, 30 

 (1917), No. 1513, p. 6). — The author reports observations which show that 

 galyl, a chemical product similar to salvarsan, has a valuable specific action in 

 epizootic lymphangitis. 



Investigations of a fungus (Monilia capsulata) found in the pus from, a 

 mule affected with epizootic lymphangitis, P. Lindner and P. Knuth 

 (Ztschr. Infeklionskrank. u. Hyg. Haustiere, 17 (1916), No. 5, pp. 200-308, pis. 

 4, figs. 2). — In infection experiments with M. capsulata the authors failed to 

 produce the disease. 



Intestinal parasites of poultry, their prevention and treatment, A. B. 

 WicKWARE (Canada Dept. Agr., Health Anim. Branch Bui. 25 (1917), pp. 13, pis. 

 3). — A popular discussion. 



Coccidiosis of the fowl, H. H. Curson (Union So. Africa, Dept. Agr. Bui. 3 

 (1917), pp. 4)- — A brief popular account of this disease, which is said to be very 

 prevalent in the Cape Peninsula and probably in other parts of South Africa. 



A means of transmitting the fowl nematode Heterakis papillosa, J. E. 

 AcKERT (Science, n. ser., 46 (1917), No. 1190, p. 394). — Recent experiments are 

 said to have demonstrated that the fowl nematode H. papillosa may be trans- 

 mitted to chickens by feeding them a dung earthworm (Helodrilus gieseleri 

 hempeli). Of ten 5-week-old chicks given the dung earthworms every few days 

 until each chick had ingested approximately 40 worms, four became infested 

 with H. papillosa. 



" Of 395 chickens taken locally and examined in this laboratory during the 

 last 3 years, 293 were infected with H. papillosa. The average infection was 

 34.4 nematodes, but a single infection of 100 nematodes is not uncommon, and 

 in one instance a fowl contained 326 of these parasites." 



While the data presented indicate that the relation of the nematode to the 

 earthworm is that of an association, in which case the eggs of the former might 

 be carried on the slimy surface of the earthworm or in its engulfed food, the 

 evidence is not such as precludes the possibility that this earthworm may in 

 some way serve as an intermediate host of H. papillosa.
