Abstract
SINCE the low-temperature thermostats on the market involving an electric refrigerator and temperature regulator are very expensive, it is possible that the following easily constructed apparatus (Fig. 1) may prove of value to many research workers. It was designed for the purpose of subjecting small aquatic animals to a constant temperature over a range of 4°–10° C. Our present apparatus will maintain a constant temperature ±0·1°C. Working at 5° C. it will consume approximately ½ cwt. of ice in 100 hours.
