Bacillus bronchisepticus (Bronchicanis) ; The cause of distemper in dogs 

 and a similar disease in other animals, N. S. Ff;rry (Vet. Jour., 68 {1912), 

 No. .'I'lO, PI). 376-391, lahlc 1). — This is a general account of the disease in which 

 the author summarizes the present status of our knowledge concerning it. 

 together with a report of investigations conducted in continuance of those pre- 

 viously noted (E. S. R., 25, p. 787). 



The infectivity of parts of organs of glandered horses, the complement 

 fixation reaction with guinea pigs, and some curative and immunizing tests, 

 H. MiESSNER {CentU. Bakt. [ctc.^, 1. AM., Orlg., 6.', {1912), Festschrift F. 

 Loeffler, pp. 121-151, pi. 1). — Only one-quarter of the guinea pigs infected with 

 pieces of the organs of glandered horses became glandered. According to this, 

 the results obtained with the infection test must be inteii^reted with care. 

 Guinea pigs infected with defibrinated blood rarely took the disease. Guinea 

 pigs infected with either the organs or blood of glandered animals can only be 

 considered glandered when the findings of the complement fixation test have 

 been confirmed by the autopsical findings or the animals have gone through 

 the course of a light form of the disease during their lifetime. Therefoi'e the 

 complement fixation reaction, when used for diagnosing glanders in guinea 

 pigs, i. e., infection tests, can not be relied upon. 



Guinea pigs were treated with mallein or a killed culture of the glanders 

 bacillus for the pui-pose of determining whether the serum of these animals 

 behaves as does that obtained from horses pretreated in the same way. This 

 was answered in the affirmative with the aid of the complement fixation test. 

 Artificial and natural gastric juice did not seem to have any particular 

 bactericidal action for the glanders bacillus. Glanders bacilli placed directly 

 in the stomach of guinea pigs produced glanders in these animals. Horses 

 which were fed cultures of Bacillus mallei, given with the food, did not contract 

 the disease. Immunizing tests with antiformiu solutions of the glanders 

 bacillus and guinea pigs showed that a single or a double treatment (given 

 subcutaneonsly or intra-abdomiually) did not produce an immunity in these 

 animals. The salvarsan treatment was not effective for glanders. 



The mallein test and its "vagaries," H. G. Simpson {Vet. Rec, 2i {1912), 

 No. 1226, pp. .'il7-430). — In this article are discussed the relation between local 

 and thermal reactions and the number and age of lesions found on post 

 mortem, irregularities of the local manifestation, deferred and double local 

 reaction, "lungers," and the results of a large number of tests and autopsies 

 conducted by the author. 



Leishmaniasis and babesiasis in Yucatan, H. Seidelin {Ann. Trap. Med. 

 and Par., 6 {1912), No. 2, pp. 295-300, fig. i).— The author states that a cattle 

 importer has estimated that the loss of imported cattle due to splenetic fever 

 (piroplasmosis) would reach as high as $70,000 within a period of 3 months. 

 Native cattle are said to suffer from the disease in a mild form. A chronic case 

 of canine piroplasmosis is reported to have been observed. 



The hemolytic action of mastitis milk, F. Moser {Centbl. Bakt. [etc.], 1. 

 AM., Orig., 65 {1912), No. 1,-5, pp. 269-296).— The milk from animals affected 

 with mastitis as a rule contains complement, the amount, however, being sub- 

 ject to a great many variations and dependent to quite an extent upon the de- 

 gree of infiammation. Milk which has a normal appearance contains little or 

 no complement. Hemolytic amboceptor was not noted. The hemolytic method 

 is considered of no value for practical purposes because simpler methods are 

 at our disposal. 



The pathological anatomy of natural and experimental murrina — a try- 

 panosomal disease of the Isthmus of Panama, S. T. Darling {Jour. Med. 

 Research, 26 {1912), No. 2, pp. 219-21,7, pis. 2). — In this paper the author reports
