would probably be such as those seen in the 

 Pongo of Wurmb. In the second edition of the 

 "Regne Animal" (1829), Guvier infers, from the 

 " proportions of all the parts " and " the arrange-

 that the Pongo is the adult of the Orang-Utan, 

 " at least of a very closely allied species/' and 

 this conclusion was eventually placed beyond all 

 doubt by Professor Owen's Memoir published in 

 the "Zoological Transactions" for 1835, and by 

 Temminck in his " Monographies cle Mammalogie." 

 Temminck's memoir is remarkable for the com- 

 pleteness of the evidence which it affords as to 

 the modification which the form of the Orang 

 undergoes according to age and sex. Tiedemann 

 first published an account of the brain of the 

 young Orang, while Sandifort, Miiller and 

 Schlegel, described the muscles and the viscera 

 of the adult, and gave the earliest detailed and 

 trustworthy history of the habits of the great 

 Indian Ape in a state of nature ; and as 

 important additions have been made by later 

 observers, we are at this moment better ac- 

 quainted with the adult of the Orang-Utan, 

 than with that of any of the other greater 

 man-like Apes.

 as certainly not the Pongo of Battell, seeing that
