Table LX111. — WeiglU, composition, and heat of combustion of feces Metabolism experiments Nos. 86-88. 



The urine was collected and the nitrogen determined in the usual 6-hour periods each day. 

 No attempt was made to dry composite samples of the urine for each experiment for the 

 determinations of carbon and hydrogen, but aliquot portions were taken from each day's urine 

 for the preparation of a 9 days' composite sample, which should represent the urine for the total 

 series of experiments. The heats of combustion of the composite sample for each day were, 

 however, determined. Statistics of the urine for experiment No. 27 are given in detail, by 

 6-hour periods, and those of experiments Nos. 26 and 2s, in which alcohol did not form a part of 

 the diet, are summarized by days, for comparison.
