Hogs and the tent caterpillar, F. M. Hayes [Jour. Amer. Vet. Med. Assoc, 

 .j.J {1918), No. 1. pp. 59-61, pi*. 4). — Investigations made of the loss of some 30 

 hogs in two weeks on two ranches in a small valley of 25 square miles in Cali- 

 fornia showed it to be due to feeding on cocoons of the forest tent caterpillar, 

 large quantities of which were found on plants along ravines and on the leaves 

 of the oak trees. Upon post-mortem examination an indigestible mass was re- 

 moved from the intestines in one continuous string. A dissection of the mate 

 rial showed it to be composed of line, wool-like fiber enmeshing bits of grass, 

 bailey hulls, and small fragments of a dark-brown material, invaginations and 

 volvulus appear to be the immediate cause of death. Treatment consists in 

 removal from the range until the adults have emerged. 



Cultivation of the causative organism of epizootic lymphangitis in series 

 and its development in the horse. L. NEQBE and A. BoQTTET [Ann. Inst. Pas- 

 teur, 82 {1918), No. 5, pp. 215-241, figs. 3; abs. in 'imp. i ,t. Bui., 6 {191S\. No. 

 S, i'i). 175 -178, figs. 3). — A detailed report of the studies noted from anothe- 

 source (E. S. K., 39, p. 789). 



Some notes on the treatment of equine ascariasis and oxyuriasis, M. C. 

 Hall, R. H. Wilson, and M. Wigdob {Jour. Ann,. \ • t. \led. Assoc., ■'>) {1918*, 



No. /, pp. 56, 57). — The authors confirm the view thai equii xyuriasis Is 



readily amenable to anthelmintic treatment, while equine ascariasis is not 

 readily amenable to anthelmintic treatment by therapeutic doses of sale an- 

 thelmintics. 



The anthelmintic treatment of equine intestinal strongylidosis, M. C. 



Hall, R. II. Wilson, and M. Wig t {Jour. Inter. Vet. [fed. Assoc., '>', {1918), 



No. I. pp. yi -*'•"' i. "Contrary to what has been supposed, the removal of 

 strongyles from the large Intestine of the horse presents do greal difficulties. 

 The remedy of choice Ls oil of chenopodium, which displays an efflcacj of Bo to 

 100 per cent when given to horses fasted 36 hours and given In doses of id to 

 18 mils, in one dose or in divided doses, accompanied by a quart or a liter of 

 linseed oil or followed one or two hours later by this amount of linseed oil. 

 The small worms, CyllCOStomum, are more readily removed than the large, red 

 palisade worms, Strongylus, probably due to the fact that Strongylus attaches 

 to the mucosa and Cylieostomum does not 



"Turpentine appears to be the second choice of the remedies tested. In 

 the doses used, iron sulphate and tartar emetic gave very poor results and 

 promised little of value In the treatment of Btrongylidosis." 



The etiology and treatment of granular dermatitis, K. Van SaceoHB&I 

 {But. Soc. Path. Exot., 11 {1918), No. 7, pp. 575 578; abs. in Trop. Vet. Bui., 3 

 {1918), No. 8, pp. 171 t7S). — Further experiments confirm the author's view- 

 that flies are the rectors of Babronema larva, the cause of summer sores, as 

 previously expressed, 1 and proved that the parasites found in the verminous 

 nodules Is an aberrani larva of If. musccB. This substantiates the view- of 

 Railliet and Henry.' 



"Horses affected With granular dermatitis often showed conjunctivitis, and 

 this was found to be set up hy the presence of small verminous nodules located 

 especially on the membrane nlctitana," 



A curative treatment regarded by the author as specific consists in the careful 

 disinfection of the sore and then the application of a powder consisting of 

 plaster of Paris 10(1, alum 20, naphthalin Id. and quinin 10 parts, or a sufficient 

 quantity of any other bitter powder. This powder effectively protects the sore
