^T. 21.] TO JOHN TORREY. 37 



thus far, been so useful to me, and I shall always wish 

 to do all in my power to render it interesting to you. 

 I shall be ready to leave this place by 1st of Septem- 

 ber next, at which time I shall probably visit New 

 York. Will you write me on this subject as soon as 

 convenient, and very much oblige, 



Yours truly, A. GRAY. 



P. S. There is within a circuit of some miles, and 

 at this place, a great variety of fossil organic remains, 

 and I am collecting them as extensively as possible. 

 We find trilobites (Asaphus, and occasionally Caly- 

 mene), a variety of bivalve and a few univalve shells, 

 etc., both in lime rock and greywacke. The cele- 

 brated locality of Trenton Falls you are of course 

 acquainted with. Would a suit of them be accepta- 

 ble to yourself, or the Lyceum of Natural History, 

 New York ? And can they be named, so that I can 

 label my collection from them ? There may few of 

 them be of any interest, but if you wish it you shall 

 have a suit containing specimens of all I find. 



UTICA, January 2, 1833. 



I received your letter of December 25, and have 

 given the subject of which you write a careful con- 

 sideration. I may say that I have no objection to the 

 situation you propose, if a proper arrangement can be 

 made. 



The terms of my engagement here are these. This 

 situation became vacant by the death of Mr. Edgerton 

 in April last. I was recommended by some of my 

 friends, and finally made an arrangement for one year ; 

 took charge of a class in botany and mineralogy on 

 20th May; closed July 30. Have been at liberty
