I thank you, dear Sir, for the copy of your Fauna Americana which you have been so kind as to send me, with the 2. interesting pamphlets on the Genus Salamandra and Agama. you have rendered a service of essential value to science in bringing to-gether the American subjects of Nat Hist. separately from those of the other quarter’s of the globe and relieving them at length from the Confusion into which they had been brought by endeavors to identify them individually with those of the old world. I am able too to make your work immediately useful by presenting it to the school of Nat. hist. of our University. withdrawn by age from the general pursuits of science, myself I am endeavoring to make my latter years useful by promoting an establmt which may befriend the progress of knolege in my own state and cooperating with the similar establmts of our sister states maintain science on this side of the Atlantic in equal advance with that of the other. be pleased to accept the assurance of my great esteem and respect.

Th: J.
