prised in that group. In some of the Didelphida, the Phalmigers 

 and Petaurists especially, there is a marked approximation to that 

 rodent form of incisor teeth which obtains in Cheiromys, and which 

 has hitherto been regarded as especially attaching to it an abnormal 

 character. 



Man is the only other animal furnished with hands ; and how- 

 ever distinct he maybe as regards his moral and intellectual powers, 

 he must, zoologically, be considered on physical grounds. By his 

 structural characters he becomes associated with all those of which 

 mention has previously been made in Mr. Ogilby's communication ; 

 although he unquestionably constitutes among them a pecuhar group, 

 sensibly exalted above the rest, as well as above all other Mammals. 



Mr.Ogilby concludes by proposing the name of Cheiropeds, Cheiro- 

 poda, to include all the Mammals that are possessed of hands ; and 

 by subjoining a table of the families and genera included in this or- 

 der, as he regards it. Of this table the following may be regarded 

 as an abstract. 



Class. Mammalia. 



Order. Cheiropoda, 



Mammals with opposable thumbs 



On the anterior extremities only Bimana. 



On both anterior and posterior extremities. . . . Quadhumana. 

 And with anthropoid teeth,

Lemuridce. 



On the posterior extremities only Pedimana. 



And with anthropoid teeth.
