An accoant of the ABACHNIDE3 of the Uoited States. 



The following descriptions of the Arachnidcs of this country, 

 which respire by means of tracheae in the manner of insects, may 

 be regarded as the continuation of a series of essays, of which the 

 " account of the Crustacea," &c., is the first, on the vast orders of

 only, as appear to be unknown to naturalists, or to the elucidation 

 of such, as from their obscurity, are not understood.
