          a fourth is coming in next steamer. 
 I have been looking at some of them 
 this afternoon (Friday) to see they 
 were in good order. 


 Please send me a recipe by 
 which a chemist can prepare the 
 arsenate of potash. I have promised 
 the prescription to Mr. Lowell. 


 Will you bring me a new stock? 


 I should have sent the 
 Mulder by mail to Henry but
 expecting you here I thought to
 save postage by giving it to you. 
 I will still retain it till you 
 come, also the Proceedings of Phil.
 Socy [Proceedings of the American Philosophical Society], which I have from his own 
 copy.


 No botanical news by the 
 Cambria. 


 My German packages 
 still stick at New York, but I 
 am daily expecting to receive them.


 Yours ever,
 A. Gr.
