Sheehy — Variation of the Constituent Substances of Cows' Milk. 581 



In this and also in another investigation, 1 the report of which is going 

 to press simultaneously, I have received much help from Mr. Carey, Albert 

 Agricultural College, Glasnevin; Mr. Torrens, Eoyal College of Science, 

 Dublin ; and Mr. E. D. Cole, Department of Agriculture, whose kind 

 assistance rendered it possible to continue the work over the long period of 

 1916 (March to November). Throughout the investigation I have got much 

 support from Professor Wilson, Eoyal College of Science, who contributed 

 many valuable suggestions, and helped to make the calculations and to 

 elaborate the reports.
