A respiration calorimeter of the Atwater-Rosa-Benedict 
type designed for use with dogs and children ; 
with demonstration.

[From the Physiological Laboratory, Cornell Medical College, New 
York City.] 
The apparatus demonstrated is in many respects a miniature 
of the calorimeters of this type which have been constructed 
at the Nutrition Laboratory in Boston. The writer wishes to 
acknowledge his great indebtedness to Dr. Francis G. Benedict, 
director of that laboratory, for his invaluable assistance in working 
out the problem of a small calorimeter. 
In order to measure with a satisfactory degree of precision 
the gaseous and energy metabolism of infants and small animals, 
it has been necessary to introduce some special modifications. 
As a detailed description of these modifications with a report of 
the control tests of the apparatus will be communicated within 
a short time, particular mention need not be made at present.

The chemical and energy transformations in the dog after the 
ingestion of different quantities of meat.

A dog weighing about 13.8 kilograms was given on different 
days, 700 grams of meat and 1,200 grams of meat at the noon 
hour. In the morning the metabolism was determined for an 
hour, while the dog slept quietly in the respiration calorimeter. 
The minimum or basal metabolism thus determined was found to 
be about 25 calories per hour. After the ingestion of meat at 
noon, the animal was again placed in the respiration calorimeter, 
and the hourly metabolism determined. The results are given 
in the following table.
