Paris, April 9, 1870 



My dcar Mr. Engelmann, 



One of my best friends, Mr. Bureau, is departing for St. Louis. I am taking this 

 opportunity to introduce him to you. 



Mr. Bureau is planning to make important zoological excursions, however, will not 

 neglect the collection of plants. 



He would like to visit, among other lœations, the régions around Lake Superior. 



I will be personally grateful for ail the services you can render this enthusiastic 

 naturalist. I do not doubt that you will be happy to make his acquaintance. I am 

 certain that you will receive him in benevolent friendship and this I will appreciate. 



Please take, dear Mr. Engelmann, my renewed expressions of affection. I send you 

 my thanks for the useful services you can provide for Mr. Bureau.
