monthly 1-day tests conducted liy the station, and the resuhs())>tained by the l)reeder 

 liiniself on the basis of monthly tests of composite samples. The average fat prodnc- 

 tion of 10 Jersey cows as determined Ijy the different tnethods was 484.9 and 480.5 

 lbs. and the average fat production of 7 Guernsey cows was 337.1 and 343.9 lbs., the 

 latter figures in each instance being the results obtained by the station. The results 

 are l)elieve(l to giv(» strong support to the system of monthly 1-day tests. 



The influence of food on milk, A. B. Graham {Tran.s. Hujliland and Agr. Soc. 

 Scotkniil, 5. ser., 10 {1904), Jip- 4S-GJ). — A detailed account is given of 3 feeding 

 experiments, the primary ol)ject of which was to determine the influence of the 

 amount of water coTisumed upon the (piality of the milk produced. In the author's 

 opinion the quality of milk is largely influenced by the amount of water consumed, 

 and the results of the experiments are l)elieved to confirm this view. 



A brief summary is given of some of the literature on this subject, and determina- 

 tions of the acidity of milk innnediately after milking and after aeration and ((loling 

 are reported. 



The influence of corn cockle on milk production, J. Hansen {Laudv. .htlirh., 

 32 {190.3) , ^Yo. ,5-0, j>ji. S99-927). — Two series of experiments with cows are reported. 

 Feeding stuffs containing 40 to 50 per cent of corn cockle were eaten by cows without 

 any injurious effects. On the whole, corn cockle exerted a more favorable than 

 unfavoraV)le influence upon the total yield of milk, and also on the yield of fat and 

 solids-not-fat. On the other hand, corn cockle exerted a very unfavorable influence 

 upon the quality of butter, and is therefore of doubtful value as a food for cows. 



Investigations on the poisonous properties of corn cockle, O. Hacjemann 

 {Lanibr. Jahrh.,S2 {1903), No. 5-6, pp. 929-94S). — The results of several experiments 

 with cows, sheep, pigs, and goats indicated that the feeding of corn cockle in the 

 amounts ordinarily found in feeding stuffs exerted no poisonous influence upon 

 domestic animals. The feeding of large quantities to cows, however, exerted an unfa- 

 vorable influence upon the (juality of the butter. 



Action of formaldehyde on milk, A. Trillat {Compt. Rend. Acad. Sci. PariK, 13S 

 {1904), No. 11, pp. 720-722). — Comparative tests were made of the digestibility in 

 pepsin solutions of (1) casein from milk treated with formaldehyde in varying 

 amounts (1:5000 to 1:20000) and curdled with rennet, (2) casein obtained from 

 freshly curdled milk and suspended in aqueous solutions of formaldehyde of the 

 strength mentioned, and (3) casein obtained from the same source but not subjected 

 to the influence of formaldehyde. 



The digestibility of the untreated casein was 5 to 6 per cent greater than that in 

 the first series of experiments, and 30 per cent greater than that in the second series. 

 Previous to the coagulation of the milk formaldehyde was recovered in practicall}^ 

 the amounts added, showing no fixation of the antiseptic. Owing to the action of 

 formaldehyde on the gastric mucous membrane, it is believed that its addition to 

 milk should be prohibited. 



Milk, T. Mackaklane {Ijd). Jnlond Rev. Depf. Oltaira, Canada, Bid. 93, pp. 15). — 

 This gives the results of the examination of 227 samples of milk collected during the 

 months of Novem))er and December, 1903, of which 159 samples were found genuine 

 or imadulterated. 



The milk supply of large towns, F. W. IIakris {Briti.^h Food Jour., G {1904), 

 No. 62, pj). 20-30). — A general discussion of this subject with special reference to 

 the milk supjily of (dasgow, analytical data l)eing given. 



Studies and observations on milk in the region of Padua, (i. Kossi {Staz. 

 Sper. Ayr. ItaL, 30 {1903), No. 10-12, pp. 6'93-925) .—TW- author presents a descrip- 

 tive account of the conditions observed in dairies in the vicinity of Padua and gives 

 the results of a large num])er of analyses of milk samples. 



Sanitary milk— its future, li. A. Pearson {Cornell Countryman, 1 [1904), No. 0, 

 I'll. 108-170, fnj. 1). — Notes are given on the pi'oduction of sanitary milk and ou the 

 outlook fortius branch of the dair\- industry.
