On the influence of pathological milk in the manufacture of cheese, F. W. J. 

 BOEKHOUT and J. J. Oit de Vries (Centbl. Bakf. [etc.], 2. Abt., 31 {1911), No. 

 23-25, pp. 559-567). — The acidity, catalase, bacterial, and leucocyte contents of 

 pathological milk are given. When not over 10 per cent of mastitis milk was 

 used for making Edam cheese it interfered but little with the normal process 

 of ripening, though the use of such milk is condemned from a hygienic stand- 

 point. 



VETERINARY MEDICINE. 



Handbook of the technique and methods for immunity research, edited by 

 R. Kraus and C. Levaditi {Handb. Tech. u. Methodik Iinmnnitdtsforsch., 1 

 (1908), pp. IV +V +1138, pis. 3, figs. 127; 2 {1909) pp. IV +1219, pi. 1, figs. 133; 

 1 (1911), Sup., j)p. 664, pis. I'h figs. 25). — The first volume of this work is a 

 comparatively complete treatise on methods of immunity research, and em- 

 braces both veterinary and human medicine. Its topics include antigens and 

 antibodies; toxins concerned in blackleg; bacterial hema toxins; snake venoms; 

 ricin, abrin, and robin ; preparation of antigens by chemical and physical 

 methods; methods of vaccinating against rabies, anthrax, blackleg, hog ery- 

 sipelas, fowl cholera, tuberculosis, peripneumonia (lung plague) in bovines, 

 rinderpest, and foot-and-mouth disease; immunizing against swine plague 

 bacteria and protozoan diseases; the use of tuberculin for diagnostic puri'oses; 

 the cutaneous and conjunctival tuberculin reactions; and mallein. 



The second volume treats of the following topics : Technique for producing 

 antibodies in large animals; method of immunizing small experimental animals 

 and of obtaining antibacterial and antitoxic immune sera from large animals; 

 production of antibodies by chemical and physical methods; tetanus and black- 

 leg antitoxins; bacterial antihematoxins; phagoc.ytosis; opsonins; bacteriolytic, 

 streptococcic, anthrax, hog erysipelas, fowl cholera, hog cholera, swine plague, 

 rinderpest, sheep pox, and rabies serums; agglutination (technique and methods) ; 

 technique and methods of protein differentiation (iirecipitin method) with 

 particular reference to forensic blood and meat examinations; bacterial pre- 

 cipitins ; anaphylaxis ; and the technique of the Bordet-Gengou complement 

 fixation method with particular reference to diagnosing infectious diseases. 



The first supplementary volume of the work treats of the following topics: 

 Avidity and determination of the avidity of antigens and antibodies, tetanus 

 toxin and antitoxin ; the intracutaneous valuation of diphtheria antitoxin ; 

 dysentery and cholera toxins and antitoxins; meningococcic and anthrax serums; 

 technique and methods for tropin research; phagocytosis and opsonins (Wright's 

 technique of vaccination); the local tuberculin reactions; anaphylaxis and 

 expei^imental analysis of anaphylactic poisons; serovaccination against hog 

 erysipelas; vaccination against tuberculosis; tuberculin preparations for diag- 

 nostic and curative puriwses; cutaneous and conjunctival tuberculin reactions 

 in the bovine; diagnosis of glanders with the aid of the new immunity reac- 

 tions; protective vaccination against rabies and antirabic serum; technique 

 for investigating acute poliomyelitis; vaccines for smallpox; the clinical utili- 

 zation of the agglutination and complement fixation tests; antibodies and 

 tuberculosis ; serum reactions with malignant growths ; hemagglutinins of plant 

 origin and their antibodies; and pathogenic micro-organisms against pests 

 (rats, field mice, etc.). 



In regard to filterable virus, Doerb (Centbl. Bakt. [etc.], 1. AM., Ref.. 50 

 (1911), Beiheft, pp. 12-23). — A critical discussion in regard to filterable viruses 

 and the factors limiting the passage of micro-organisms, etc., through a bisque 

 filter.
