ANALYSES OF FOODS, FEEDING STUFFS, ETC. 195 
ANALYSES OF FOOD MATERIALS. 
In the Report of this Station for 1891 the results of some 
325 analyses of materials used as food of man were given. 
Since then not far from 1,000 specimens of such food materials 
have been analyzed by the Station. The results of these analy- 
ses have not been published in detail, because of the large 
expense of such printing in the reports of the Station, and the 
hope that a place would be found for them in Government 
publications where they would have a wider circulation. An 
especial reason for such publication is found in the fact that a 
considerable share of the analyses were made in the course of 
inquiries carried out by the Station in codperation with the 
Government. This was true of some 600 analyses of food 
materials collected at the World’s Fair in Chicago in 1893. 
But while the details are still unpublished the final results 
have been included in summaries published by the Station,* 
and more especially by the U. S. Department of Agriculture.t 
Partial reports of some of the analyses have been published in 
connection with accounts of dietary studies and digestion or 
metabolism experiments in connection with which the analyses 
were made. 
The Station has also analyzed from year to year considerable 
numbers of feeding stuffs in connection with experiments upon 
the effects of fertilizers on the growth and composition of 
crops, and feeding and digestion experiments with cows and 
sheep. The results of these analyses have been given in the 
_ Reports of the Station. In the present Report it has seemed 
best to include the results of all the analyses, both of foods 
and feeding stuffs, made during the year 1896-97 in con- 
nection with investigations published in the present Report. 
The food materials were those used in the digestion and 
metabolism experiments with men, described elsewhere in the 
present Report. 
Table 46 shows the composition of the food materials at the 
time of sampling, and table 47 the composition of the same 
when calculated to the water-free basis, z. e., the composition 
of the dry matter. ‘The heats of combustion were determined — 
in the bomb calorimeter. It is to be noted that the fuel values
