Extract

1. Details are given of the construction of one open-circuit and two closed-circuit respiration chambers suitable for the determination of the 24 hr. exchange of energy of calves or of other animals weighing up to 75 kg.

2. Gas analysis apparatus and the general technique employed in experiments with the closedcircuit apparatus are described.

3. From experience gained with both types of apparatus the closed-circuit apparatus is preferred for its simplicity and ease of working.
