134 STORRS AGRICULTURAL EXPERIMENT STATION. 
As stated above the amount of exercise was not large. It 
consisted mainly of the labor required in light housekeeping 
and in short walks. Even in the coldest weather much of 
the time was spent sitting in the open air, well protected by 
wraps. i 
The studies here reported were made in the winter (No. 
184), spring (No. 202), and summer (No. 223) of 1897. ‘The 
winter study comprised six weeks in February and March. 
The minimum temperature during the month of February was 
—28° F., the maximum -+50° and the approximate mean 
18°. During this period from.5 to 5% hours per day were 
spent out of doors, and at night the windows of the sleeping 
room were left open. ‘The subject estimates from numerous 
observations of the thermometer that the temperature of the 
air in the sleeping room was, on the average, not far from 
15° F., and that the mean temperature of the air in which 
he lived during the period was not far from 35°. During 
the period of 14 days in May, when the spring dietary study 
was tnade, the minimum temperature recorded was 29”, the 
maximum 78° and the mean not far from 53° F. (obtained by 
averaging the maxima and minima for the different days). 
The average temperature of the air in which he lived he esti- 
mates to have been about 56° in the day time and 47° at night. 
The summer study was made in August, it continued 14 days, 
during which period the minimum temperature was 38°, the 
maximum 83°, and the mean about 62° F. Many of the 
temperature records were furnished by the weather observer 
at Saranac Lake not far distant. 
Results.—The study of the previous winter (January and 
February, 1896) had shown a daily consumption of food suffh- 
cient to yield 200 grams of protein and a fuel value of 4,335 
calories. ‘The unusually large values shown by this study led 
to a reduction in the amounts of food eaten, so that the winter 
dietary here reported, continuing for six weeks in February 
and March, showed but 186 grams of protein and 3,750 calories 
of energy in the daily food. ‘The results obtained in the two 
weeks’ study in the following May again show a marked de- 
crease in both the protein and energy of the food consumed, 
the protein amounting to 130 grams per day, and the fuel value 
to 2,805 calories. In the summer study, carried on during two
