NUTRITION INVESTIGATIONS OF STORRS STATION. Lon: 
needs of the body for nourishment were also obtained from 
respiration calorimeter experiments. Detailed accounts of the 
work with this apparatus have been published from time to time 
by the Office of Experiment Stations of the U. S. Department of 
Agriculture. Such publication is appropriate not only because 
the wide distribution obtained is fitted to the general interest of 
the subject, but also because the resources of the Government 
Printing Office permit the publication of important statistical 
details which would be far too voluminous and expensive for an 
experiment station or private report. There is now in prepa- 
ration a bulletin of the Office of Experiment Stations which 
gives the details of the late experiments with the respiration 
calorimeter and summarizes all of the general results obtained 
up to 1902.* ‘The list of subjects treated in this bulletin in- 
cludes the following: 
Kinds, amounts and composition of food materials. 
Digestibility of food and availability of energy. 
Quantity and composition of products excreted by the lungs 
and skin, kidneys and intestine. 
Summary of data of income and outgo of individual experi- 
ments. 
Demand of the body for nourishment. Dietary standards. 
Elimination of carbon-dioxid, water and heat. 
Body temperature. 
Heat production vs. heat elimination. 
Estimates of amounts of oxygen consumed. 
Respiratory and thermal quotients. 
Amounts of energy derived from different nutrients. 
Fats vs. carbohydrates as protectors of body material. 
Fats vs. carbohydrates as sources of energy for muscular 
work. : 
Carbohydrates and fats vs. protein as sources of energy for 
muscular work. 
Efficiency of the body as a machine. 
Conservation of energy in the body.
