Experimental researches on the bacteriological and intoxicating character 

 of the lactic acid food, " Gioddu,'' of Sardinia, G. Rosmi {Mod. Zooiatro, 

 Parte Set., 1913, No. 3, pp. 87-100). — An account of the Italian lactic acid drink, 

 " Gioddu," corresponding to yoghourt, koumiss, and kefir, and for which is

VETERINARY MEDICINE. 



Regional anatomy of domestic animals, L. Montan:^ and E, Bourdelle 

 (Anatomie Regional des Animaux Domestiques. Paris, 1913, pp. 1069; rev. in 

 Rec. M6d. Vet., 90 {1913), No. 5, pp. 195-199) .—This is a new work intended for 

 both the student of veterinary medicine and the practitioner. 



Meat hygiene, T. E. Munce {Penn. Live Stock Sanit. Bd. Circ. 26, 1913, pp. 

 Jf8, pis. 3, figs. 19). — This reports upon the abattoirs and meat inspection work 

 in the larger municipalities of Great Brtiain, France, Germany, and Netherlands. 

 A plan for either a private or municipal slaughterhouse is included. 



Principles of milk hygiene for veterinarians, W. Ernst {G-rundriss der 

 Milchhygiene fur Tierdrzte. Stuttgart, 1913, pp. VIII +301, pis. 5, figs. 26).— 

 This is the first edition of this work, which seems to have many features that 

 are different from other works previously published on milk hygiene. Its con- 

 tents are as follows: Anatomy, pathology, and the finer structure of the mam- 

 mary gland; physiology of milk secretion and properties of milk in general; 

 microscopy of milk ; composition of milk and its biologi(^l, chemical, and physi- 

 cal properties ; the production of cow's milk ; internal and external causes 

 affecting the composition of milk ; bacteria in market milk and their origin and 

 action upon milk ; control of the milk supply ; laws relating to the milk supply ; 

 and the examination of milk. 



The book is illustrated with many plates and drawings. 



Miiller's serodiagnostic methods, P. T. Muxler, trans, by C. R. Whitman 

 {Philadelphia and London, 1913, 3. ed., pp. XIII +146, figs. 7). — ^A clear, concise 

 description of the methods used in serodiagnosis, with especial reference to 

 human medicine, translated from the third German edition. 



On the mechanism of complement fixation, H. R. Dean {Jour. Hyg. [Cam- 

 hridge^, 12 {1912), No. 3, pp. 259-289; al)s. in Ztschr. Immunitdtsf. u. Expt. 

 Ther., II, Ref., 6 {1913), No. 15, p. 1118).— The author finds that by making a 

 series of dilutions with antisera, it is possible to determine the point where a 

 definite amount of antigen will combine with the complement. In the absence 

 of the latter it will give no precipitate, but if complement is added, a precipitate 

 appears after several hours. By adding more complement a limited increase in 

 the precipitate is noted. 



Instead of using complement the same results can be obtained with the 

 euglobulin prepared from guinea-pig serum. The precipitation of euglobulin is 

 practically the same as that produced by carbon dioxid. The middle portion is 

 fixed much quicker by the precipitation of an antigen-antiserum mixture than 

 the end portion. The results show that the fixation of the constituents of com- 

 plement is similar to the fixation which occurs with inorganic substances, e. g., 

 barium sulphate suspensions, and that adsorption plays an apparent rOle in 

 complement fixation. 



Meiostagmin reaction and pregnancy, A. Pulchiero {Biochim. e Terapia 

 Sper., 4 {1912), No. 3, pp. 58-61; a'bs. in Ztschr. Immunitdtsf. u. Expt. Ther., II, 

 Ref., 6 {1913), No. 15, p. 1056). — In the experiments 35 sera from pregnant 

 women and 35 control sera were examined with the meiostagmin reaction, 

 3 different kinds of methyl alcohol extracts being employed. All of the
