 This work by various authors treats of the subject as follows: Volume 1, 

 operative technique, by J. Bayer; volume 2, general surgery, by E. Frohner; 

 volume 3, parts 2 and 3, the head, neck, chest, and abdomen, by B. Hess et al. ; 

 volume 4, part 1, the extremities, by several authors and part 2, hoof diseases 

 of the horse, by R. Eberlein ; volume 5, diseases of the eye, by J. Bayer; volume 



6, skin diseases, by H. Schiudelka ; and volume 7, bovine obstetrics, by M. G. 

 de Bruin. 



The diagnosis of pregnancy in animals by the optical and dialysis methods, 

 E. Abderhalden and A. "Weil (Berlin. Tierdrztl. Wchnschr., 28 {1912), No. 36, 

 pp. 665-667). — This is a continuation of the studies noted (E. S. R., 27, p. 577). 

 The investigation, which was made with 12 cows, gave positive results in 10 

 cases. The dialysis method is easier to conduct, but the nature of the cleavage 

 process can not be determined. The method of conducting the tests is given in 

 detail. 



The colloids in biology and medicine, H. Bechhold (DieKolloide inBiologie 

 und Medizin. Dresden, 1912, pp. XII+Ji//4, pis. 2, figs. 52). — ^The purpose of this 

 book is to point out the colloid phenomena which occur in biology and medicine. 

 It includes an introduction to the methods of colloid investigation, and a dis- 

 cussion of the biocolloids (carbohydrates, lipoids, proteins, foods and condi- 

 ments, enzyms, and immunity reactions), the organism as a colloidal system 

 (metabolism, the cell, blood, respiration, resorption and secretions, secretions 

 and excretions, etc.), toxicology and pharmacology, and microscopical technique. 

 A bibliography is appended. 



The passage of drugs into the sweat, H. Tachau {Arch. Expt. Path. u. 

 Phannakol., 66 {1911), No. 5-6, pp. 33-'f-3.'i6; ahs. in Jour. Ghem. 8oc. [London], 

 102 {1912), No. 592, II, pp. 18.), J8.5 ).—lodiu, bromin, boric acid, phenol, sali- 

 cylic acid, salol, antipyrin, and methylene blue were found to be excreted in 

 the sweat but the amount was small, as they pass into the milk and other 

 secretions. The amount may be sufficient, however, to cause skin eruptions in 

 certain cases. 



The chemical examination of death camas, F. W. Heyl et al. (Wyoming 

 Sta. Bui. 94, pp. 3-31, figs. 3). — The work here reported relates to Zygadenus 

 intermedins, also known as poison camas, lobelia, squirrel food, wild onion, 

 lX)ison sego, poison sego-lily, mystery gi'ass. etc. The alkaloid found in this 

 plant is most abundant in the flowers, which contain approximately 1.25 per 

 cent. The bulb and the leaves and tops contain approximately 0.6 per cent, 

 and the roots but half that amount. Guinea pigs, dogs, and frogs were used 

 in determining the physiological effect of the alkaloid and the antidotes.
