Buffer Fat Studies. — Experiments to note the effect of 

 coconut, corn, peanut and soy bean oils upon the chemical 

 character of butter fat have been made during the past year, 

 but owing to the interference of other work the laboratory 

 studies have not been completed. Methods, either direct or 

 indirect, have already been devised for determining with a 

 reasonable degree of accuracy the percentages of the several 

 soluble and insoluble fatty acids of butter fat, and the work 

 of studying food influence is being prosecuted as fast as time 

 will permit. 



Insecticides and Fungicides. — A considerable amount of work 

 has been done upon insecticides and fungicides in co-operation 

 with the Department of Entomology, and a number of pro- 

 prietary products have been examined. 



Several poison cases have been investigated for other de- 

 partments of the College. While this latter is not research 

 work, it was quite necessary and reciuired the services of a 

 specialist. " 



A method of analysis of lime-sulfur mixtures has been 

 developed which will be submitted for publication in some 

 chemical journal. The method is adapted to the analysis of 

 any of the water-soluble sulfides. 



Animal Nutrition. — A thorough study has been made of the 

 nutritive value of oat by-products, — hulls, middlings, and the 

 mixture of the two, known as mill run oat feed, — and the 

 results are now in press. 



Digestion studies with sheep have been completed with the
