Water loss from the sweat glands of shorn sheep was estimated as the difference between the average weight gain of desiccating capsules placed on 10 normal sheep and on 4 control sheep congenitally lacking sweat glands. At an air tempera ture of 20°C (68°F) and a water vapour pressure of 12.5 mm Hg the rate of svveating was 10.2 g/m2/hr, and at 40°C (104°F) and a water vapour pressure of 28.1 mm Hg the rate of sweating was 32.1 g/m2/hr. The maximum amount of heat a sheep could lose by sweating at the rate of 32 g/m2/hr under these conditions is c. 20 kcal/hr. It is emphasized that the rate of sweating observed in shorn sheep must not be applied unreservedly to sheep with a fleece, because the dynamics of water movement in the fleece are unknown.
