148 ProfeJJbr camper on the Organs of 
the bones of the carpus do not entirely agree with his 
defcription, though he feems to have been very exaffc 
and nice in his diffections. And indeed I wondered as 
often as I compared the lircuSture of the carpus and tar- 
Jus of apes, monkies, and dogs, with galen’s ojleological 
performances upon this fubjeCt : for though he defcribes 
but eight bones in the carpus , he mentions the ninth, 
which I have met with in all monkies, apes, and dogs, 
and likewife in the Orang. The tenth is not eafily feen, 
it being very much attached to the os navicular e. Thefe 
bones I fhall give the explanation of in the anatomical 
defcription of the Orang. 
In the Angolefe Orang, Dr. tyson met with the ver- 
micular procefs of the intejt. caecum , which I found very 
confiderable in the Afiatic; but of which galen appears 
not to have had the leaft notion. Mr. d’aubenton has 
given the defcription and figure of the fame little gut in 
the Gibbon, a fpecies approaching to that of the Orang, 
and likewife an inhabitant of Afia, but alfo unknown 
to GALEN. 
§ 3. I fhall now proceed to the organ of fpeech itfelf,. 
and defcribe it as it appeared in the firft Orang I diifccled 
in October 1770. And for the clearer underftanding I 
fhall add fome figures to it; firfi, of the fore-part; 
1 fecondly.
