in the etiology and spread of Mediterranean or Malta fever, including a review 

 of tlie literature pertaining to this disease. The subject is treated under the 

 following headings : The history and dispersion of Malta fever ; the appearance, 

 culture, and vitality of Micrococcus vielitcnsis ; symptoms, diagnosis, and pro- 

 phylaxis of Malta fever; the infection of goats with M. melitensis; the relation 

 of goat's milk and cheese to Malta fever in man; and the detection of un- 

 hygienic milk by chemical analysis. 



It is concluded that Malta fever is transmitted to man almost wholly by 

 drinking raw milk from infected goats or by eating curd or cheese made from 

 goat's milk. In infested districts goat's milk should not be used unless it has 

 been boiled and cheese from goat's milk should not be eaten unless it is very old. 



Hereditary transmission of rabies, D. Konradi (Ann. Inst. Pasteur, 30 

 (1916), No. 1, pp. S3-Jf8; abs. in Amer. Jour. Vet. Med., 11 (1916), No. 10, pp. 

 808, 809). — The author concludes in this paper, continuing previous work 

 (E. S. R., 20, p. 279), that with dogs, rabbits, guinea pigs, and probably other 

 animals the rabies virus is transmitted from mother to fetus, but its vii'ulence 

 gradually diminishes. See also other notes (E. S. R., 22, pp. 587, 682). 



A modification of tlie Hyg'ienic Laboratory m^ethod for the production of 

 tetanus toxin, Harriet L. Wilcox (Jour. Bad., 1 (1916), No. 3, pp. 333-338). — 

 A method essentially the same as that used at the Hygienic Laboratory of 

 the U. S. Public Health Service,* with a few slight variations, is described 

 in detail. 



A new culture medium for the tubercle bacillus, W. W. Williams and W. 

 BuRDicK (Jour. Bact., 1 (1916), No. 4, pp. 41I-414). — The preparation of an 

 egg-meat infusion culture medium containing gentian violet as an inhibitor of 

 the growth of contaminating micro-organisms is described in detail. A method 

 of isolating tubercle bacilli from sputum is also described. 



The combined and follow-up systems of tuberculin testing, G. H. Hart 

 and J. Traum (Jour. Amer. Vet. Med. Assoc, 50 (1916), No. 2, pp. 189-214). — 

 This is a general discussion of the subject, together with some experimental 

 data from which it is concluded that tuberculous animals, while giving nega- 

 tive results to one form of tuberculin application, may give positive reactions 

 to another form. The value of combining two or more tests and following 

 with further tests several weeks later on all nonreacting animals is deemed 

 evident. The value of the follow-up test is to detect animals in the incubation 

 stage or those which were insensitive to tuberculin for other reasons at the 

 time of the previous test. The ophthalmic test, together with an intradermal 

 injection, is considered to be a very satisfactory combination. 



Studies in infectious abortion in cattle, W. Giltner, E. T. Hallman, and 

 L. H. CooLEDGE (Jour. Amer. Vet. Med. Assoc, 49 (1916), No. 3, pp. 320-339). — 

 This article contains tabulated serological data obtained in a comparison of 

 the complement fixation with the agglutination test for contagious abortion, 

 together with temperature charts of nonpregnant animals which had received 

 two injections of living organisms and of pregnant animals receiving injections 

 of dead organisms. 



From comparative data it appears that the complement fixation test will 

 indicate more reactors than the agglutination test. However, animals were 

 found to react to the agglutination test and not to the complement fixation 

 test. 



The material by Cooledge previously noted (E. S. R., 34, p. 679) is also 

 Included.
