N2 - 1. Blood flow and the concentrations of noradrenaline, adrenaline and dopamine were determined in the skins of cattle and goats, before, at the onset of and 3 hr after commencement of sweating induced by heat exposure (40°C). 2. The onset of sweating in both cattle and goats was associated with a rise in cutaneous blood flow, which was thus independent of sweat pattern. Cutaneous blood flow was also higher at 40°C than at 15°C. 3. The predominant catecholamine in the skin of both species was dopamine, which in the goat increased in concentration in the warm environment. 4. There was no clear evidence of a change in the amount of any of the cutaneous catecholamines during exposure to 40°C, although there was a consistent tendency for the concentrations of adrenaline in the calf and noradrenaline in the goat, to fall during the onset of sweating.
