876 EXPERIMENT STATION RECORD. [Vol. 37 



Certain theoretical considerations are presented which lead to the hypoth- 

 esis that the gas separates iu aggnegates according to laws governing the 

 separation of gas from supersaturated aqueous solutions. This hypothesis has 

 been tested upon viscous media with results directly applicable to the " eye " 

 and " Nissler " hole formations in cheese. 



It is concluded that the gas produced in Emmental cheese separates in ag- 

 gregates whose localities have no necessary relation to the points where the 

 gas is produced, and that a rapid gas production must tend to the formation 

 of numerous small holes while a slow gas production must admit the forma- 

 tion of larger holes. This conclusion is shown to agree with the fact that 

 Nissler holes are produced by a rapid fermentation while eyes are formed 

 slowly. This conclusion also suggests that the gas of Nissler holes must sepa- 

 rate at numerous points near its point of origin without regard to any particular 

 locality of the cheese, while the eyes must form at favorable points. This 

 was experimentally verified by a study of stain,ed cheeses. 



An extensive bibliography is given.

Sugar in the treatment of wounds, S. Koheya {Chosen Igaku Kai Zassi, No. 

 IS (1916), pp. 11-18; abs. in Japan. Med. Lit. [Korea], 2 (1911), No. 1, pp. 7, 

 8). — The successful use in wound treatment of commercial granulated sugar is 

 iiete<l. The sugar was found to inhibit the growth of most of the bacteria liable 

 to be found in wounds. It possessed no disinfecting power, but stimulated tissue 

 granulation and the formation of epithelial cells, prevented putrefaction of the 

 secretions, and reduced the odor. 



The use of chloramin-T paste for the sterilization of wounds, M. Dau- 

 FRESNE (Jour. Expt. Mcd., 26 (1917), No. 1, pp. 9i-9.?).— " Dakin's toluene 

 sodium p-sulphochloramid, mixed with sodium stearate, forms a paste sufficiently 

 active and stable to be used in the treatment of wounds." 



Sterilization of wounds with chloramin-T, A. Cakrel and Ai.ice Habtmann 

 (Jour. Expt. Med., 26 (1911), No. 1, pp. 95-118, figs. 20).— "Under the condi- 

 tions of our experiments chloramin paste maintains the asepsis of a wound 

 already sterile, and sterilizes an infected wound. Under the same conditions 

 chloramin paste causes no apparent modification of the cicatrization curve of 

 an aseptic wound." 



Dichloramin-T in the treatment of the wounds of war, J. E. Sweet (Jour. 

 Amcr. Med. Assoc.,' 69 (1911), No. IS, pp. 1076-1078; Brit. Med. Jour., No. 2956 

 (1911), pp. 249, 250). — The author concludes that Dakin's dichloramln-T in 

 solution in eucalyptol and paraffin oil is of great advantage in wound treat- 

 ment, even when the final results in wound healing are no better, because it 

 saves the pain of wound dressing, it effects an appreciable saving of dressing 

 material, the amount of solution is of small bulk, the number of wounds which 

 a surgeon can dress in a given time is far greater than by any other method.
