Some Bats are of considerable dimensions. There is one 

 species in the island of Java {Pteropus Javanicus), the ex- 

 panse of whose wings is so much as five feet. It is probable 

 that some of the large Indian Bats, with their predatory 

 habits and obscure retreats, may have suggested to Virgil 

 the idea of the Harpies, " which fell upon the hastily-spread 

 tables of his hero and his companions, and polluted, whilst 

 they devoured, the feast from which they had driven the 

 affrighted guests. "f 



Order QUADKUMANA.— MONKEYS. 



"Meddling Monkey — busy Ape." — Shakspeaee. 



Those who have visited a zoological garden, or a well-stocked 

 menagerie, cannot foil to have been amused at the freaks and 

 gambols of the monkeys ; and after watching for a time their 

 agile movements and grotesque attitudes, must have been 

 struck with the peculiar formation of the extremities, both of 

 the feet and of the paws. The feet are not shaped like ours, 

 but resemble hands, being furnished with fingers and with 

 thumbs. In fact, they do not perform the functions of feet 

 only, but of hands also. Hence that order to which the 

 Monkeys belong is termed quadntmana, or four-handed. 



We are not, however, to suppose that eveiy individual 

 belonging to this group possesses both on hands and feet a 

 thumb which can be applied or opposed to each of the fingers. 

 The American Monkeys, for example, are by this single cir- 

 cumstance distinguished at once from those of the Old World. 

 They have the full power of using the thumbs which are on 

 the feet, but not tliose which are on the anterior extremities. 

 By such dififerences, and by those in the dentition, the pre- 

 sence or absence of cheek pouches, and other peculiarities, 

 the order is subdivided into families, genera, and species. 



We shall briefly notice the Lemurs of INIadagascar, the 

 Monkeys of America, and those of the Old World.
