If there is anything you would like to know or if you will be served with any 

 one cactus or its blossoms please let me know. I will do all that is in my power 

 to do. Friend Lindheimer has given me information of all books known to him and 

 G. Schleicher, our representative in Washington, an old acquaintance of mine, will 

 be good enough to try to obtain them for me in Washington, I think that is the only 

 and best way. Yours has already given me much Service, perhaps I can obtain it in 

 this way, because Mr. Lindheimer needs his himself. 



Pespectfully your, 



Otto Ludwig
