1100 EXPERIMENT STATION RECORD. 



The food production of British farms, R. H. Eew {Jour. Roi/. Arjr. Soc. Eng- 

 land, (!-} {190.)), ]ij>. JIO-IJJ). — Statistics regarding the production of vegetable and 

 animal food products on British farms are summarized and discussed. 



Borax and boric acid as drugs and preservatives ( Borax und Borsuure als 

 Arznei- nnd Konserrlerungsmitti'l. Nuremhng: Bund Dtutschtr NahrungsniiUel- Fabri- 

 l-anten- und Handler, 1903; rev. in Ztschr. Fleisrh- v. MUchhyrj., 14 {1904), No. 8, p. 

 291). — A summary of data regarding borax and Ixiric acid. The general conclusion 

 was drawn that these substances have not been shown to be harmful when used as 

 food preservatives. 



Anilin dyes, G. "\V. Chlopin {Kamennougolnuiya Kraski. Dorpat: K. Matluev, 

 1903, p]>. 300). — The author reports the results of an elaborate study upon.the com- 

 position and effects upon animal life of various dyestuffs made from coal-tar products. 

 The different dyestuffs are classified according to their chemical relationship and 

 notes are given on the characters of the various groups. 



Numerous experiments were made in testing the effect of anilin dyes in food prod- 

 ucts upon the animal organism. It was foimd that a consideral)le variety of these 

 dyes were harmful. The majority of poisonous dyestuffs belong to the nitro, azo, 

 and triphenyl groups. While these groups are mentioned as especially poisonous, 

 the author maintains the general proposition that all anilin dyes are more or less 

 injurious to the animal organism and that their use in food products should be pro- 

 hibited by law. (See E. S. R., 15, p. 494.) 



A ne-w type of anemo-calorimeter for clinical uses, A. 0. Ignatowski {Arclt. 

 Physiol. {Pfluger'], 102 {1904), No. 5-6, pp. 217-248, figs. ^).— In the apparatus 

 described the temperature is measured by the speed of a small windmill driven by 

 the escape from the calorimeter chamber of air warmed by the patient's body. The 

 apparatus is of such a size that it maj- be jilaced over a cot. 



Concerning the artificial transformation of albumin into globulin, L. Moll 

 {Hofmeister' s Beitr., 4, No. 12, p. 563; abs. in Zentbl. Physiol., 18 {1904), No. 2, pp. 

 41, 42). — Blood serum warmed for an hour at 60°, when diluted with water and 

 acidulated with dilute acetic acid, gave a much larger precipitate than untreated 

 blood serum and was found to contain an increased amount of globulin and alkali 

 albuminate. The effect of lower temperature was also studied, and experiments 

 are reported on crystallized serum albumin and its behavior toward a number of 

 reagents. 



In general, it was found that the globulin formed depended upon the concentration 

 of the albumin solution, increasing with the increased concentration. Carbonates, 

 bicarbonates, and phosphates of the alkali metals had an equally marked effect; the 

 hydroxids, the least marked. 



The cleavage of gelatin, II and HI, P. A. Levene {Ztschr. Physiol. Chem., 41 

 {1904), No. 1-2, pp. 8-14, 99, 100). — Products obtained from gelatin by ferment 

 action were studied, in continuation of earlier work (E. S. R., 14, p. 992). 



Concerning ferments in organs which induce cleavage in sugar, J. Fein- 

 sciiMiDT {ITofineister's Beitr., 4, No. 9-11, p. 511; ahs. in Zentbl. Physiol., 18 {1904), 

 N'o. 2, pp. 49, 50). — The glycolytic power of different organs of several animals Avas 

 studied. 



Concerning the coagulating effect of autolytic organ extracts on albumose 

 solutions and on milk, A. Nurxberg {Hofmeister' s Beitr., 4, No. 12, p. 543; abs. in 

 Zentbl. Physiol., 18 {1904), No. 2, p. 43). — The effect on albumose solutions and milk 

 of the extracts of various organs submitted to self-digestion was studied. 



On the adaptation of the pancreas, F. A. Bainbridge {Jour. Physiol., 31 {1904), 

 No. 2, 2^p. 98-119). — A number of exj^eriments with dogs are reported. Among the 

 conclusions drawn were the following: 



"The pancreas of adult dogs normally contains no lactase, although this enzym is 

 present in extracts of the intestinal mucous membrane of such dogs; yet when dogs
