438 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



investigations in the general appropriations for the Department of 

 Agriculture have been: 



For the fiscal year 1894-95 $10, 000 



For the fiscal year 1895-96 15, 000 



For the fiscal year 1896-97 15, 000 



For the fiscal year 1897-98 15, 000 



For the fiscal year 1898-99 15, 000 



For the fiscal year 1899-1900 15,000 



For the fiscal year 1900-1901 17,500 



For the fiscal year 1901-2 20,000 



The contributions from other sources are not easily estimated in 

 terms of money, since they consist in large part of use of laboratories, 

 apparatus, and other facilities for research, and the counsel and help 

 of experts and other gratuitous service. The State of Connecticut 

 makes a small annual appropriation for nutrition investigations to 

 the Storrs Experiment Station, which cooperates with the Department. 

 A considerable number of experiment stations, educational institu- 

 tions, philanthropic organizations, and private individuals have given 

 sums of money to promote the cooperative inquiry. 



It would be entirely wrong to attribute the whole of the results 

 described beyond to this especial inquiry. Indeed, it represents sim- 

 ply a special movement begun after others had been long in operation, 

 and is now running parallel with them. 



NUTRITION INVESTIGATIONS IN THE UNITED STATES. 



Until within a very few years, the most definite knowledge regarding 

 the nutritive values of food and the laws of nutrition has come from 

 Europe, but lately such information has been accumulating quite 

 rapidly in the United States. A complete historical review of investi- 

 gations upon food and nutrition in this country would include numer- 

 ous instances in which studies of food were incidental to other 

 inquiries. A considerable amount of valuable information has been 

 obtained by physicians, by State boards of health, and by specialists in 

 physiology, hygiene, and dietetics. Some of the latter inquiries are 

 of especial value, as, for instance, those of Professor Chittenden, of 

 Yale University. Of noteworthy importance are the studies of the 

 chemical composition and adulteration of food materials made in the 

 Division of Chemistry of the Department of Agriculture by Prof. 

 H. W. Wiley and others. 



The purpose of the present article is to refer to the special work 

 which has developed into the cooperative inquiry now being carried 

 on under the auspices of the Department of Agriculture, through the 

 Office of Experiment Stations, and to describe some of the methods, 

 progress, and results of that enterprise. This inquiry had its incep- 

 tion in a study of the chemical composition of food-fishes and inver-
