Neuro-Endocrine Research Unit, Staten Island, New York Willowbrook State School, DEVJCE HAS BEEN DEVELOPED for the combustion of acetone at a known, constant rate within a metabolism chamber to provide standard oxygen consumption and carbon dioxide production rates for calibration purposes. In the calibration of metabolism apparatus which measure the total oxygen consumption and carbon dioxide production during a test period, it is not essential for a calibrating device to have a uniform combustion rate. The calibration of such systems has been well covered (1-3). However, we have been concerned with the problem of testing the over-all accuracy of an opencircuit metabolism chamber for young children. In this system a fresh current of air was constantly passed through the apparatus and the oxygen consumption rate (Beckman, model G2 analyzer used) was calculated from analysis of the oxygen deficit in the exhaust current. This type of system has already been described (4-6). Such a system requires a testing apparatus with a uniform combustion rate. This was accomplished by carefully metering a current of air through a vessel containing acetone at a constant temperature and conducting the vaporized acetone to the chamber for combustion. permitted
