The volatile fatty acids by the Reichert-Meissl-Wollny method were 

 28.4 per cent. 



A milk behaving similar to the above, which was produced by a 

 Shorthorn cow in another locality, had the following composition:

Microscopic examination of the first sample showed " that the fat 

 globules in this abnormal milk are very large, practically double the 

 diameter, that is, eight times the size of those in the milk of our Jersey 

 breed, which is admitted to have the largest. The mean diameter of 

 the globules in the Edingham milk was less than the Belford sample, 

 having an average of 0.0003 in. The surface tension of the suspended 

 fat globules in both milks was very low, pressure on the cover glass 

 being sufficient to make them lose their apparently circular shape and 

 run together with great readiness." In all probability the size of the 

 fat globules explains the abnormality. 



Subsequently a number of other cows were heard of whose milk 

 showed similar abnormality. 



Annual Report of Oerebro Chemical and Seed-Control Station 

 for 1893, J. Widen {Oerebro {Sweden), 1894, pp. 43). — The report gives 

 a summary of the work done during 1893. The chemical station ana- 

 lyzed 3,394 samples in all, 2,158 of which were of milk and dairy prod- 

 ucts and 898 to be examined for arsenic. The detailed results of the 

 analyses are given in the report. The new milk examined contained, 

 on an average, the following percentages of fat during the various 

 months of the year :
