 Dear Doctor, 


 I have been waiting 
 to hear whether you are coming 
 to see us or not. 


 Sprague has two more 
 drawings ready Chamaebatia &
 the new genus (very) near Philadelphus. 
 He is now at Hymenoclea 
 please send or bring your specimen. 
 Mine is so poor, has no 
 stam. fl. [stamen? flower?] & few leaves. At any 
 rate send me aome stam. fl. 
 with the axis in a letter if
 you don't come. Sprague has 
 it partly done; & will do the 
 eleventh as soon as I pick out the 
 thing.
