noted there as yours & your specific names as recorded in tlu- 

 " Catalogue oj Insects of Pennsvlrania " shall be preserved in 

 every instance that your numbers ( which I have always re- 

 tained attached to the Insects you sent me) in my Cabinet, 

 will enable me so to do, with the exception only of such names, 

 as have been applied to other insects of the same genus 



I thank you much for the handsome manner, in which 

 you have been pleased to express your approbation, of my 

 attempt at descriptions of our Fresh Water & Land Shells, I 

 was urged to do it by finding them entirely overlooked in the 

 publications of late authors ; Several shells have been since 

 added to the list, which I will communicate to you in the 

 "Journal of the Academy of Natural Science" a small work 

 we are issuing here, from the Society that I informed you of, 

 when I had the pleasure to be at your house. This little work 

 I will be careful in future to send to you as early as it appears, 

 though I do not know how 7 long it may continue to be issued ; 

 you w r ill see in the ' ' Journal ' that I have been describing 

 the Crustacea of our waters ; but my dear sir, I assure you 

 that Shells and Crustacea are but secondary things with me, 

 INSECTS are the great objects, of my attention, I hope to be 

 able to renounce everything else & attend to them only- 



I sent for some of the books you informed me of, to Paris, 

 & have recieved intelligence from my correspondent there of 

 their having been shipped, so that they may be expected every 

 day. 



I have made out a monograph of the Cicindela of N. America 

 which will soon be published with figures, it shall be sent to 

 you as soon as it appears, There are twelve species described. 

 I w r ould give you here a further account of it but my paper 

 warns me to stop- 

 Most respectfully I remain your friend 

 & Obd 1 . Serv 1 . 



Thomas Say. 



I yesterday sent you a copy, through the Post-office, of the 

 fifth number of the Journal of the Academy of Natural 

 Sciences Tomorrow I will send the Sixth number I hope 

 they may be duly received
