Reverend and Ueah Sik : 



iMalacological Science is indebted to you lor the development of most of the 

 ITiiionidaj which I have described from Georgia, and I liave a lively sense of the able, prompt and efficient 

 aid rendered by you, which lias enabled me to bring to public view the extraordinary treasures of your 

 State. The unvarying kindness shown in responding to my calls upon you, makes me feel that to no one 

 could I more appropriately, or with more pleasure, inscribe a volume which historically records the result 

 of a portion of your own labors. 



Very respectfully and very sincerely yours, 



ISAAC LEA.
