IO STORRS AGRICULTURAL EXPERIMENT STATION. 
man in the respiration calorimeter, studies of the digestibility 
of mixed diets, and studies of actual dietaries. Summaries of 
the work done and statements of the most important results 
obtained and conclusions reached, have been given in publica- 
tions of the Station for the past few years and may be found 
in this Report. The full details, which are too voluminous 
for publication by the Station, and are of such general interest 
as to call for wider distribution than it could give them, are 
published by the Department of Agriculture. These investiga- 
tions form a part of a more general inquiry which is authorized 
by Congress and is carried out in different parts of the country 
under the authority of the Secretary of Agriculture, who has 
placed them in charge of the Director of this Station. 
Dietary studies.—The studies of actual food consumption of 
groups of people and of individuals form as in the past one of 
the important lines of inquiry of the Station. During the past 
eight years the results of over 350 dietary studies in the United 
States have been reported, the majority of which were con- 
ducted by experiment stations and other institutions in coop- 
eration with the U. S. Department of Agriculture as a part of 
the general inquiry just mentioned. Of these studies about 
fifty were carried out by this Station. The work of the past 
year includes the study of the actual food consumption at two 
of the buildings of the Connecticut Hospital for the Insane 
during one week, and several dietaries of families and indi- 
viduals for various periods. 
Digestion experiments.—Twelve experiments upon the diges- 
tibility of food by man were made during the past year. The 
results obtained in these and similar investigations elsewhere, 
together with those obtained from analyses of food materials 
and from determinations of heats of combustion by use of the 
bomb calorimeter, have been utilized in deriving the data for 
the availability and the nutritive value of American food 
materials which are summarized in one of the articles of this 
Report. ) 
Metabolism experiments.— Eleven metabolism experiments 
were carried on during the past year, the details of which will 
appear in Bulletins of the U. S. Department of Agriculture. 
Some of the results of the work are given in the present Report.
