 My Dear Sir,


 I have neglected to acknowledge
 the receipt of your very valuable letter of May
 last because I thought you might be absent
 from N. York on account of the fever & because
 I have been as much occupied as a feeble state of health
 would permit me to be That letter was indeed a valuable
 acquisition to my knowledge of our cryptogamia
 _ & I return you many thanks for your
 kindness in naming so many specimens- The
 specimens of [Sphaeria?] - S. [cuniratris?] Schw. is abundant
 [?] on rocks _ or the [crossed out: [light one?]] thin soil on rocks
 [?] think I can find the locality again without
 difficulty & if I mistake not I have somewhere
 among my arranged duplicates a consideable
 quantity of it so that if you wish I will send you
 some. The nov. sp. of Boletus - B. delicatulus Schw
 is [?]. I have but few specimens & it is doubtful whether
 I can find more.


 The [paintings?] reached me safely & I thank
 you for the [corrections?] of the ^ [inserted: naming of the] phenogamous plants.
 There were some marks such as X attached to some
 species that I did not understand and which led me
 to suspect that you had forwarded a letter with
 them & that it is lost. And you mentioned also in
 your last letter that you should send a letter with
 the paintings. I shall regret if it is lost. I have
 had [Persoon?] the past summer & though I have found
 little time to attend to the subject yet I find the [book?]
