My Dear Mr. Engelmann, 



Our good friend Len^rmani has informed me that you are still studying the Cuscutees. It will give me pleasure 

 to send you some blades. "Et in Arcadia ego". Over here I have had the opportunity of studying the plants 

 physiologically; my work was quite advanced and had it not been for the question in regards the formation of 

 the embryo, I would already have sent it to be printed. I am forced to pospone this until next summer as I have 

 to finish this important endeavour. I published in the Annals the anatomy of the parasites of the Cuscutees. I 

 have been able to observe them on différent plants and see their shapes change considerably to the point of 

 making me think that there are several types, when I had under my eyes a single one, the C. epithymum. 



I hope you will be interested in the objects that I sent you from the Muséum, described by Mr. Choisy, and that 

 you will take them into considération even though I send them in the form of pustules. 



One of my good friends, Dr. Lé^^illé, offers you together with our common acquaintance Mr. Agassiz, a 

 pamphlet that was written here. You know the country side well and therefore you have been able to collect ail 

 the mushrooms that you wish. I must say that The Muséum will profit fi-om samples and Mr. Leocille could find 

 thèse as publishing material You will not see pamphlets that are not of the highest quality and that would merit 

 your support,By collecting for him many mushrooms, that without doubt grow in the country where you live, 

 you will help him. 



If on this side we can be helpfiil to you, please employ us without scruples. 

 I hope that this letter will find you in good health, happy and content. 



Always at you service, 



J. Decaisne
