80 EXPERIMENT STATION RECORD. [Vol.41 



is not applicable. The udder of this kid had not been massaged, suckled, or 

 treated in any way to stimulate Its growth or secretion. It is possible that 

 some other of the internal secreting glands have a prominent part in regulat- 

 ing the growth and secretory activity of the mammary glands. There is 

 some evidence [as noted above and in another publication of the author (E. S. 

 R., 36, p. 573)] in favor of the theory that the pituitai-y body (hypophysis 

 cerebri) may function in this way." 



The milk analyses and the author's theory of colostrum formation are re- 

 peated from another paper (E. S. R., 38, p. 780). The literature on the 

 physiologj' of milk secretion is reviewed. 



A new and powerful g'alactagogue, C. H. Duncan (N. Y. Med. Jour., 105 

 (1917), No. 1, pp. 22, 23). — Several cases are cited in which the milk flow of 

 the nursing mother (human) was apparently increased by subcutaneous in- 

 jection of 1 cc. of her own milk. The statement is made that veterinarians 

 have successfully treated cows by similar methods. " This treatment should 

 be brought to the attention of the cattle raisers, stockmen, farmers, dairymen, 

 etc., for if this treatment is judiciously given it will insure the animal giving 

 the maximum amount of milk of which she is capable. . . . The writer sug- 

 gests that practically every cow be treated as indicated to insure her doing her 

 duty toward supplying milk." 



Milk as a galactagogue, L. S. Palmer and C. H. Eckles (N. Y. Med. Jour., 

 108 (1918), No. 9, pp. S75, 376).— The authors have attempted to verify the 

 above-noted theory using cows of the Missouri Experiment Station herd. Two 

 experiments were performed in which 20 cc. of milk from fresh heavy milking 

 cows was injected subcutaneously on three successive days into the shoulders 

 of cows advanced in lactation. The results were entirely negative. In a 

 third experiment, after a cow was milked dry 20 cc. of milk was injected and 

 the cow milked again in an hour, when 85 gm. of milk was secured. On the 

 previous day the same procedure without injection resulted in 200 gm. of milk. 



Since Duncan's treatment seems to have been most effective in cases of 

 sudden cessation of milk flow the authors suggest that the injected milk served 

 as a counterdepressant and not as a galactagogue. 



Principles and practice of milk hygiene, L. A. Klein (Philadelphia: J. B. 

 Lippincott Co., 1917. pp. S20, figs. ^0). — This book is intended primarily as a 

 text for students pursuing a course in milk hygiene. 



The utilization of dairy by-products, E. Ket.t.y (Jour. Dairy Sci., 2 (1919), 

 No. 1, pp. 46-^9). — Attention is called to the food lost to the people of the 

 United States by the waste of skim milk, buttermilk, and whey, and general 

 suggestions made regarding methods of utilization. It appears that only six 

 States have laws requiriag pasteurization of skim milk and whey destined for 

 human consumption. 



The practical cultivation of the green mold (Penicillium glaucum) for 

 making blue cheese, R. Chavastelon (Compt. Rend. Acad. Agr. France, Jf 

 (1918), No. 18. pp. 56^-566). — By the method proposed very thin slices of bread 

 (wheat or rye) are soaked in a 35 per cent solution of tartaric acid, inoculated 

 on both sides with Penicillium spores, kept on screens or straw mats (previously 

 sterilized) in a moist atmosphere for a day or two, and then, when colored a 

 uniform green, dried in the air and pulverized. Practically nothing is left by 

 this time of the original bread and the residue consists almost exclusively of 

 spores suitable for use in cheese making. 



The method commonly used by makers of Roquefort cheese is to steep large 

 pieces of rye bread in vinegar to which spores have been added, but this is 

 considered xmdesirable aside from the waste of material since acetic acid is not 

 so favorable a culture medium for Penicillium as for some other molds.
