Speech of the Orang Outang. 147 
The Orang Outangs defcribed by tulpius and tyson 
came from Angola, and had both black hair, and large 
nails upon the great toes. I own the figures of thefe 
great men are very deficient in many refpedts : but, upon 
the whole, the animals are reprefented and defcribed 
as very ftrong and mufcular; whereas all the Orangs 
from Borneo, I have feen, were the, contrary, and had

which I diffedted 1777. This one had the os hyoides like 
all the papiones or fphinges, 8cc. ; the epiglottis perforated 
as in fig. 3. and 4. and therefore different from galen’s 
defcription, and from tyson’s, who makes no mention 
at all of the one, nor of the two bags which galen de- 
fcrihes, and which I found in the real Orang of Borneo ; 
not only in one fpecimen, but in five, which I have 
differed for that purpofe. 
To return to galen; I am very apt to think that he 
diffedted an Afiatic Orang, from whom he took his de- 
fcription of the ventricles a latere lingulce_ , at the fides of 
the epiglottis', at leaf!: that he diffedted fuch an organ, for
