inequalities of temper are seen rather in individuals captured at an ad- 

 vanced period of life than in those taken young. To capture these, the 

 Indians wound or kill the mother, and then, without difficulty, seize the 

 young ones, which she carries on her back. 



Very nearly allied to the common Uistiti is the Ilapale aurita, or 

 eared Uistiti, with fur of russet black, streaked on the back with faint 

 black bands ; also the cowled Uistiti (Ilapale humeralifer), with white 

 face, surrounded with brownish hair, blackish body, a collar of snowy 

 white on the scapular region, and tail bearing incomplete rings. These 

 two species are, like Hap>ale vulgaris, natives of Brazil, and, like that 

 animal, they are noticeable for the tufts of white hair which grow on 

 the anterior surface of the ears. In other Uistitis, on the contrary 

 (as the Ilapale penicillata), and the white-headed Uistiti (Ilapale leu- 

 cocephala), which inhabit the same regions, the tufts on the ears are 

 black. Finally, in the black-tailed Uistiti (Ilapale melanura),o$ which, 

 in all probability, Buffon's Simla argentata is only an albino variety, 

 the hair, which is light brown, is very short, and the tail is of a uni- 

 form, light-brown color. To the same category belong the Pygmy 

 Uistiti (Hi pale pygmaia) of which we give a figure copied from na- 

 ture and the white-footed Uistiti (Ilapale leucopus), a species de- 

 scribed last year by Gray, and which has the forearms, feet, and hands, 

 of a nearly pure white color, while the rest of the body is brownish 

 gray, with more or less mixture of red. This animal was discovered at 

 Medellin, in Colombia; while the Ilapale pygmaia which differs from 

 it both in markings and in size, having red spots and blackish streaks, 

 and being much smaller than Leucopus is confined to certain regions 

 of Brazil and Peru. La Nature.

SOME years ago, a clergyman in one of our Western States became 

 deeply impressed with the conviction that the town in which he 

 lived ought to contain a college. In due time a charter was secured, 

 and a board of trustees appointed. They met, organized, conferred 

 upon the aforesaid clergyman the degree of D. D., and then adjourned 

 forever. I give the story as I heard it, without undertaking to vouch 

 for its truthfulness. It savors somewhat of extravagance, and yet has 

 a sound of probability. Everybody has heard of the establishment of 

 so-called "colleges" upon similarly slender foundations. They exist 

 in almost every Southern or Western State, and because of them our
