176 EXPERIMENT STATION" RECORD. [Vol.37 



From the study with Edam cheese reported it is concluded that independent 

 of the amount of paracasein present the digestion (ripening) proceeds slowly 

 until a definite concentration of split products is reached. This explains the 

 fact of a larger percentage digestion of cheese material in a sample rich in fat 

 than in a sample poor in fat. The stimulating action of the fat on the casein 

 could not be determined. 



The judicial problem of Camembert, F. Mabee (Le Problime Juridiquc du 

 Catnembert. Paris: Editions Scientiflques Francaises [1915], pp. 141)- — In addi- 

 tion to notes on the history, manufacture, composition, definition, and fat con- 

 tent of Camembert cheese, this book deals with the legal status of this cheese 

 in France. 



The " cracking " of Edam cheese, F. W. .7. BoEKHOtrr and J. J. O. de Vbies 

 {Verslag. Landbouwk. Onderzoek. Rijkslandbouicproefstat. [Netherlands], No. 

 20 (1917), pp. 71-78, pi. i).— The results of the study reported indicate that the 

 use of saltpeter has very little effect in preventing the cracking of Edam cheese 

 when Bacillus coli communis and B. lactis aerogencs are present with the 

 butyric acid bacteria. The former organisms destroy the preservative before 

 it can suppress the development of the butyric acid organisms. 



VETERINAEY MEDICINE. 



A text-book of the principles and practice of veterinary medicine, D. S. 

 White {Philadrlplna: Lea d Fcbigcr, 1917, pp. -}&^). — This work, prepared for 

 use as a textbook by students of veterinary medicine, is based upon the author's 

 personal experience for over 20 years as a teacher of veterinary students. 



The comparative resistance of bacteria and human tissue cells to certain 

 common antiseptics, H. A. Lambkkt (-lour. Expl. Med.. 2-J (1916). No. 6. pp. 

 6S3-6S8). — Tills material has been previously noted from another source (E. S. 

 R., 36. p. 177). 



The prophylaxis of the infection of war wounds. — A comparative study 

 of various antiseptics, H. Vincent (Compt. Rend. Acad. Sci. [Pari.*], 16i 

 (1917), No. S, pp. 153-156). — The antiseptic and germicidal value of sodium 

 fluorid, sodium formate, zinc chlorid, calcium hypochlorite, boric acid, sodium 

 borate, copper sulphate, ferrous sulphate, potassium permanganate, and iodo- 

 form was studied by noting the action of the substances on a bouillon culture 

 of Bacillu,t perfringens. 



All the substances except boric acid and sodium borate were found to be very 

 active. Copper sulphate yielded excellent results. Sodium fiuorid was al.so 

 found to posse.ss excellent germicidal properties, but possessed a certain toxicity. 

 The most satisfactory antiseptic used was a mixture of 10 parts of fre.sh calcium 

 hypochlorite and 90 parts of crystallized boric acid in aqueous .solution. This 

 antiseptic was also found to possess hemostatic properties. 



The treatment of wounds in war by magnesium sulphate. A. E. Morison 

 and W. J. Tui.LOCH (Jour. Roy. Army Med. Corps. 27 (1916). No. 4. pp. 575- 

 ,398, pis. 2). — "From the first series of experiments it appears that magnesium 

 sulphate exhibits to a greater degree than do the other salts invest igatt^l the 

 desirable property of interfering with the digestive activity of pus. This 

 statement is made witli reservation as the experimental methods that one 

 is forced to employ are open to certain criticisms, and I suggest that the rate 

 of epithelialization of the wounds treated would give a truer index of the 

 property than does experimental inrestigation. 



" Magnesium sulphate has not so markedly inhibitory an action on phago- 

 cytosis as one would expect, and, therefore, even if it be absorbed to a slight
