 Department. Forms for a constitution and by-laws of tlie association and the 

 conti'act used in organizing it are given. 



The influence of food on the composition of milk, A, Ciccarei.li (Gior. R. 

 Hoc. Ital. Ig., 31 {WOO), No. 7, pp. 30S-3W; <ibs. in Milchw. Zcntbl., 6 (1910), 

 No. 9, p. Jf2S). — The addition of beet chips to a normal ration did not appear 

 to affect tlie composition of the milk, but an exclusive beet chip diet caused 

 tlie milk to be poor in protein and fat. Such milk is not recommended for feed- 

 ing infants. 



On factors influencing' the functional activity of the mammary gland, 

 G. d'Erbico (Pediatria [Naples], 18 (1910), No. J,, pp. 253-260; abi^. in Rev. 

 IJyg. et Med. Infant., 9 (1910), No. 5-6, pp. 5J,1, 5//2).— The author's experi- 

 ments with dogs indicate that a ferment is produced in the fetal membrane 

 which causes hypertrophy of the mammary gland. An intravenous injection 

 of defibrinated blood obtained from a pregnant dog inhibited milk secretion 

 of a lactating female dog, but the blood of a normal animal did not have this 

 effect. 



Fermented milks, L. A. Rogers (U. 8. Dept. Api'., Bur. Anim. Indus. Rpt. 

 1909, pp. 133-161, fig. 1; Circ. Ill, pp. 133-161, fig. i).— This contains a sum- 

 mary of investigations on the biology and therapeutic value of fermented milk 

 preparations sold under various trade names, as zoulak, vitallac, yoghourt, mat- 

 zoon, bacillac, kefir, koumiss, and lactobacillin. The methods of preparation are 

 discussed, and a bibliography of 76 titles is appended. 



Notices of judg'ment (U. S. Dept. Agr., Notiees of Judgment 812, pp. 2; 

 836, p. 1 ; 8Jf5, pp. 2). — These relate to the adulteration of butter and condensed 

 milk. 



The extra cost of producing" clean milk, G. M. Whitakeb (U. 8. Dept. 

 Agr., Bur. Amm. Indus. Rpt. 1909, pp. 119-131, pis. h, fig. 1; Circ. 110, pp. 119- 

 131, pis. Jf, fig. 1). — ^The aim of this article was to furnish accurate statements 

 as to what modern sanitary milk means and the extra cost to the dairyman. 

 Some of the conclusions are as follows : 



" To increase the score of a dairy from 42 to ajiproximately 70 points, there 

 may be in 15-cow dairies an added expense of 5 cts. per cow per day for labor, 

 plus, in extreme eases, 5* cts. for new or additional equipment; and if we add 

 5 cts. more to remunerate the proprietor for his extra care and vigilance, there 

 will be an extreme increase of 151 cts. per cow jier day. The product of a cow 

 ranges from 4,000 to 10,000 lbs. of milk a year, or from 5 to 12 qts. a day. 

 The added expense for labor would, therefore, amount to about half a cent to 

 1 ct. a quart, and in the rare instances where great additional expense is 

 required for repairs, new construction, and new equipment this might raise the 

 increase 1 to 2 cts. a quart more. . . . This addetl expense of improved 

 methods and equipment, however, would no doubt be partly offset by increased 

 production and increased economy of feed, so that the net extra expense of 

 producing clean milk would probably be somewhat less than the figures given. 

 ... A reasonably clean milk is worth 2 cts. more than common slovenly milk. 

 The former is safer, and therefore cheaper, at the increased price." " Dirty 

 milk ought not to be considered a merchantable article at any price, no matter 

 bow low." 



Medical milk commissions and bovine tuberculosis, E. C. Schroeder ( U. 8. 

 Dept. Agr., Bur. Anim. Indus. Rpt. 1909, pp. 193-200). — This is a paper pre- 

 sented before the American Association of Medical Milk Commissions at St. 

 Louis, Mo., June, IDIO, and is a consideration of the susceptibility of persons to 

 bovine types of tubercle bacilli and of the occurrence of tubercle bacilli in milk.
