The combating of bovine tuberculosis on the basis of mutuality, Morey 

 (Rev. G6n. M6d. Vet., 21 (1913), Xo. 2//7, pp. 365-395).— X discussion in regard 

 to tuberculosis as it exists among dairy and other animals in the districts 

 of Charolles, Autun, Chalons-sur-SaOne, Louhans, and Milcon. The author 

 proposes to eradicate tuberculosis by a mutual process, which is to include 

 the activities of both the society of owners of the cattle and the State. The 

 tuberculin test is to be used with a system of marking the tuberculous animals, 

 marks which resemble the Murphy button used in intestinal surgery being 

 placed on the left ear of the animal. The cost of eradicating the disease on a 

 mutual basis is discussed.

 A description of two cases. 



In one case the right lung showed pale yellow cheesy-calcified nodules rang- 

 ing in size from a pinhead to a bean. The left lung showed large gray foci 

 which when cut through showed a whitish yellow, creamlike, smeary mass 

 inclosed in a gray white capsule. The trachea was filled with a slimy purulent 

 secretion in which tubercle bacilli could be easily detected. The enlarged 

 bronchial and mediastinal lymph glands also contained tubercle bacilli. 



The other case represented a high grade of generalized tuberculosis of the 

 lungs, liver, and kidneys. This animal was 7 years old and very cachectic. 

 The bovine type of bacillus was noted in this case. 



A preliminary report on the investigations of bovine redwater (cystic 

 hematuria) in Washington, J. W. Kalkus {Washington Sta. Bid. 112, pp. 27, 

 pis. 10). — ^This report is based upon investigations commenced by the station in 

 1908. The results have been summarized by the author as follows : " Redwater 

 is a specific disease of cattle and is quite common in the western part of Wash- 

 ington. It is characterized clinically by the constant or periodic discharge of 

 bloody urine and by its chronic course; and pathologically by the characteristic 

 vascular lesions which occur on the bladder mucosa. The cause of the disease 

 is yet to be discovered. 



" Blood of sick cows seems to be inocuous to healthy ones. The disease has 

 beeil apparently transmitted from a sick to a healthy cow by inoculation of the 

 latter with the bladder lesions of the former. Although some drugs seem to 

 render temporary relief, treatment as a whole has been very unsatisfactory. 

 Permanent recoveries from redwater are doubtful ; a cow once affected with the 

 disease nearly always eventually succumbs to it." 



Studies on hog cholera^ — Spirochaeta suis, its significance as a pathogenic 

 organism, W. E. King and G. L. Hoffmann {Jour. Infect. Di^seascs, 13 {1913), 

 No. 3, pp. 463-498, pi. 1, figs. 44). — Continuing the work already noted (E. S. R.. 

 29, p. 681 ) the authors now report that 8. suis is found in the intestinal ulcers, 

 crypts in the ceca, and in the external local lesions of animals suffering from 

 hog cholera. The spirochete resembles in many respests S. pallida, S. galU- 

 narum, and other forms, and appears to be capable of breaking up into gran- 

 ules. These granules, the authors believe, may play an important part in the 

 life cycle and physiological functions of the spirochete, as suggested by the 

 notes of Fontes on tuberculosis (E. S. R., 27, p. 285). They are present in the 

 blood of cholera hogs, and in cultures of (Sf. suis, and are capable of producing 

 the disease in healthy hogs. 



"In the blood of hogs suffering from cholera the presence of a relatively 

 large spirochete in few numbers has been riecognized. As this organism has not 

 been found in the blood of normal hogs, it may represent 8. suis in a tran-
