          please to accept my thanks for Wm. [Brown's?] cat
 alogue.  To Dr Gray I am much obliged for
 his manag. of the Am. [?] and his re-
 marks on the [Ceratophyflacea?]


    After I left N. York I spent a week very
 agreeably in Phil and the May following
 was (unexpectedly to me) elected a correspondent of
 the Acad. of Nat. Sci.


    Please to excuse this tedious letter - My
 respects to Dr Gray and  believe me sincerely
 your most obedt. servt.


                           A. Clapp
