Did he get a sample of the alleged sweat? Was it eccrine or apocrine
Since the evidence appears to be anecdotal, I wouldn't give it much weight
until other possible causes had been eliminated; e.g. saliva, residual
in their fur, etc.

In laboratory tests, the experimenters were not able to induce sweating in
chimpanzees even when the temperature was taken above the range
they would naturally encounter. (My source is Elaine Morgan's work. I
haven't checked her citations on this issue).
