 Recd [Received] Aug. 18th 1839


 My dear Sir!


 I profit with great pleasure from the opportunity presented by the bearer
 of this letter Dr. Lilienthal, for writing to you and assuming the honour
 of your Correspondance. The young medical gentleman, whom I dare
 introduce to your kindness by these lines, can say to you, that I never
 stopped in advancing so much as possible, our common friend the
 amabilis scientia; but even the many occupations, arisen from the professorship
 entrusted to me since the removal of the University from [Lanhard?]
 to the metropolis and the manifold exertions, necessary for bringing
 to an end my long lasted extensive publications on the Brazilian Natural
 history, have prevented me from a correspondence with you, which
 in every case ought to be very honorific and useful to me.


 For this moment I am happy to present to you two small papers, which
 I beg you, to accept with kindness. I send with the same occasion
 the conclusion of my Nova Genera et spec. plant. brasil to the
 Lyceum of N. H. at History, and I shall continue from time to time
 by sending some other parts of the work, whose [illegible] is to great and
 to expensive for being given.


 The young medical gentlemen, whom I present to you with these
 lines is a very good student (who followed likewise my lectures 
 on Botany) and shall now endeavour for taking his abode in
 the U. States. If you can be, as I hope you can, of any use to
 him, I shall be very thankful to you. Pray, give me, if possible 
 some notice, about you, your health (which, as I lament, 
 was bad in the last years), your literary pursuits, and so
