DEAR. SIS, 



'npHE inclofed obfervations are at your

 the nunnber of books, but not to the ftock of 

 faas, I fend them to you in as (hort a compafs 

 as pofTible. They are not fo fit for the public 

 eye as I could wifh ; but if you think then^ 

 worthy of a place in your Tranfaftions^ yp^ 

 are welcome to them. 



Be affured. Dear Sir, of the great regard of 



Your friend and humble fervant, 



BENJAMIN RUSH.
