Dear Sir, 



Mr Hering, who is in St. Louis, will be so kind as to be in charge of bringing you thèse letters which include 

 many good wishes. During your too short stay in Paris, you encouraged me to résume our relationship; today I 

 offer you this possibility. I do not hesitate to ask you to put me in contact with one or two of your friends that 

 deal with Cryptomany. When asking this I realize that your médical practice does not give you many moments 

 of leisure. They are principally the Lichens and the Mushrooms. The fîrst are easy to prépare in large numbers 

 and the second can also be conserved. I count on your permission to be able to enrich the herbarium of the 

 Muséum. This demand has no other goal than to increase a portion of our collection that was allowed to fall 

 behind by our predecessors. In other words, if in your environs, you could find siHconized vegetable fossils, you 

 would help Mr. Armgniare and I help science. With conscientious care my friend has made public the fossil 

 végétation in the Garden of Plants, to which he adds more plants every day. In the meantime dear Sir, I would 

 not make ail thèse demands if it were not my désire to help you in some way over here. Therefore please let me 

 know in what way I may be agréable to you. Also please give me the address that I should use in New Orléans 

 so that I can send you several brochures that are destined for you and in this way continue this relationship with 

 you, that will always be very amiable. 



Goodbye, dear Sir, allow me to profit of this occasion to renew the assurances of my sincère attachment.
