 Doctor John Torrey

 Dear Sir,


 Knowing that you have many correspondents
 in Europe, with whom you change plants, and
 supposing, that you have perhaps not always
 specimens enough of our flora, I propose to send
 you a collection of my duplicats [duplicates] for the purpose
 of changing, of which you will find many specimens
 of each species. They are carefully prepared,
 and a great part of them with roots and 
 fruits. I send you therefore the here adjoined
 catalogue of my duplicats [duplicates], and if you consent
 to this proposition, you will oblige me very
 much, by making it known to me immediately,
 for these duplicats are packed and ready,
 if you wish to have them. I would like
