skim milk, milk weigh can, vat. and beater deducted) the percentage of i 

 would be 1.4. 



It is also shown that the drip method of sampling milk, by which the samples 

 are caught by means of a pet cock placed la the pipe leading from the heater 

 to the separator is accurate enough to make possible the determination of daily 

 overrun without the necessity of a daily analysis of the milk furnished by each 

 patron. The average error of 48 samples was 0.39 per cent. 



Centrifugal recovery of cheese from buttermilk, A. E. 1'i.ukins [Mo. liul. 

 Ohio Sta., 3 (1918), No. 12, pp. 367S70).— This article reports the BUCCesafnl 

 use of a centrifuge for separating the curd in the manufacture of cottage cheese 

 from buttermilk on a large scale at an Ohio creamery. The machine is a 

 modification of that used in laundries for drying garments and has a bowl ca- 

 pacity of 12.5 fml.

 Three papers are presented. 



I. Upon an inquiry as to dried milks, with special reference to their use in 

 infant feeding, by F. J. II. Coutts (pp. 1-138). — This report includes a history 

 of dried milk and methods of preparation and distribution, its physical and 

 chemical characteristics and bacteriology, and its use in infant feeding. 



As a result of the inquiry, the author concludes that dried milk is a valuable 

 food and one which possesses certain special advantages which are likely to 

 lead to its use being greatly extended in the future. Among these advantages 

 are portability, keeping properties, freedom from bacteria, convenience, ami 

 freedom from waste. For infant feeding, dried milk of recent manufacture 

 and made of a good quality of cow's milk is considered a safe substitute when 

 breast feeding is Impossible. An extensive bibliography is appended. 



II. Some investigations bearing on the nutritive value of dried milk, by 

 G. Winfield (pp. 139-156). — This report is based partly on observations made 

 at infant welfare centers and partly on feeding experiments made on animals. 

 The growth curves of children fed on dried milk resemble closely the average 

 growth curve of breast-fed children. Teething and walking began at normal 

 ages and no greater liability to rickets or scurvy was shown. 



These results, combined with those of feeding experiments on rats, led to the 

 conclusion that " cow's milk during the process of desiccation loses none of 

 the characters which are necessary for the support of normal growth in 

 infants." 



III. On the examination of mill: powders at the Government laboratory, by 

 J. J. Dobbie (pp. 157-1S4). — This report presents in detail the methods of ex- 

 amination and the results obtained in the analyses of a large number of com- 

 mercial samples of dried milk, earrled out under the direction of G. Stubbs. 



Dried and condensed milk, Baixand (Jour. Pharm. ct Chim., 7. ser., 18 

 (1918), No. 12, pp. 363-365). — Analyses of condensed and dried milk from dif- 

 ferent countries are reported. 



Fermented milk, B. W. Hammer and A. J. Halser (Iowa Sta. Circ. 54 

 (1918), pp. If).— The manufacture and use of buttermilk, kelir whey, kefir, and 

 lactade tire briefly described.
