cxiuiiined. Tlio treatment consisted in isolation of t\w sick animals and a 

 tiioronsli disinfection of the premises. 



A disease simulating dourine caused by filaria, H. T. Pease (Jour. Trap. 

 Vet. ScL. 1 (190(>). .Af>. '/. ini. 'i l'i-'il(i) . — Notes are given on a few eases which 

 have been observed among horses in which irregular i)la<iues appeared on 

 various parts of the skin together with other symptoms which closely resemble 

 those of dourine. A careful study, however, showed that the cases were not 

 dourine and that the animals did not readily spread contagion. An examina- 

 tion of the affected patches showed the presence of a filaria. 



The interaction of Trypanosoma equiperdum and T. evansi, A. Lingard 

 {.tour. Trap. \'(t. Sri.. I {1!)ih;), A'o. //. pp. .l').i-3Si;. pis. 3). — In the course of his 

 study of trypanosome diseases the author found that mares which had suc- 

 cessfully passed through an attack of dourine and resisted a second inocula- 

 tion of the same disease do not thereby acquire any imnuniity to T. evansi. 

 Similarly, ponies and donkeys, after recovering from dourine. succumb readily 

 to surra. It appears, however, from experiments with donkeys that immunity 

 acquired during pregnancy may be transmitted to the offspring. 



Vaccination against swine plague and hog colera, O. Profe (Fortscbr. 

 Vet. Hijg.. .'t (IDOG). \o. 8, pp. 169-176). — A brief account is given of several 

 of the sera which have been proposed for use in the treatment of this disease. 

 In one instance where Kletfs serum was used a cure was brought about in bogs 

 which had just begun to show symptoms of swine plague and the disease was 

 prevented from developing in exposed hogs. Of three hogs which were badly 

 affected at the time of vaccination one recovered while the other two succumbed. 



The pectoral form of swine plague, Enders (Berlin. Tieriirstl. Wchnschr., 

 liiOii. \n. J/!), pp. 867-870). — On the basis of an extended study of different 

 forms of swine plague the author comes to the conclusion that the catarrhal 

 form of pulmonary inflammation in swine plague is the most frequent. It 

 was also ascertained that there are cases of pleuritis of a specific and infec- 

 tious nature due to swine plague, but without an.v evidence of pneumonia, and 

 on the other hand there are cases of pneumonia due to swine plague which 

 are of a catarrhal nature and in which the pleura is not affected. In some 

 instances, the author observed swine plague in the form of an exclusive in- 

 flammation of the pleura without any involvement of the lungs. 



The transmission of swine erysipelas, .Schmuck (Berlin. Tierurztl. 

 Wehnnclir.. 1906, A'o. //7, p. S//7). — The author relates the circumstances of the 

 infection of one of his bands while examining the heart of a hog dead of the 

 disease. The infection spread downward along the tliunil) and upwai'd to the 

 wrist, after which the disease healed spontaneously. 



The fluid of echinococci and cysticerci, E. .Joest (Zt.'^rhr. Infektionskrank. 

 u. Hmi- Tlaiistiere, 2 (1906), No. 1. pp. 10-28).— The bladder fluid of echino- 

 cocci and Ciisticereus temiicoUis when inoculated intravenously or into the body 

 cayit.v jiroduced no effect on experimental animals and therefore may be consid- 

 ered as containing no poisonous princii)le. It was further demonstrated that the 

 blood serum of animals affected witli echinococci and cysticerci exercises no 

 precipitating effect up<m the fluid of these parasites. 



The occurrence of trichinae in rats, I.. Rahr (Zl.sclu: Infektionskrank. u. 

 llpil. Ilaiistiere. 2 (l!)(i6). Xo. I. pp. 62-6.1). — Statistics are given on the occur- 

 rence of trichinie in rats with esjiecial reference to the connection between the 

 Itarasitism of these animals and pigs. The author believes that in many 

 instances the infestation of pigs with trichinse can not be accounted for by 

 supposing that they ate infested rats. This assumption becomes improbable 

 when it is considered that high-grade hogs are commonly raised under condi- 

 tions where they seldom ha\-e opportunity to eat rats. The author believes that
