and to the farmer and all other classes of people as consum- 

 ers of food. These have resulted in giving great aid to what 

 is now a widespread movement for the betterment of public 

 and private instruction regarding human physiology and hygi- 

 ene, and for the application of the results of scientific research 

 to the improvement of the dietaries of different classes of 

 people. These results are being applied in the feeding of the 

 army and navy, and in making up dietaries for public and 

 private institutions where large numbers are fed. t They are 

 especially needed and useful for farmer's families. 



The particular feature of these nutrition investigations 

 that is of the widest scientific interest is the inquiry carried 

 on with the Atwater-Rosa respiration calorimeter, an appara- 

 tus devised and elaborated at Wesleyan University in con- 

 nection with the researches carried out in cooperation with 

 the Storrs Station and the U. S. Department of Agriculture. 

 Within this apparatus a man spends a number of days in 

 active exercise or in complete rest, while the investigation is 

 carried on in such a way as to show the demands of the body 

 for nutriment under different conditions of work and rest, the 

 duties performed by the different nutrients of food in supply- 

 ing the needs of the body, and the nutritive values of food 

 materials and the amount and proportions best adapted to the 

 needs of people of different classes, with different occupations 

 and in different conditions of life. 



The value of this kind of research is not confined to the 

 nutrition of man, but is useful also in the investigations of the 

 economic feeding of domestic animals. An apparatus similar 

 to the one in use at the Storrs Station, but large enough for 

 experiments with oxen, is being built at the Experiment 

 Station at the State College in Pennsylvania. In Europe, 

 appropriations have also been made for similar apparatus for 

 domestic animals at the Institutes of Animal Physiology at 

 Bonn and at Budapest. 



Our limited space will not allow a history of this move- 

 ment, in which the Storrs Station has taken such an active
