 My Dear Doctor


 It is a pity to tax you 
 with postage, but I must write a hurried 
 line by this day's mail, which even 
 now I must send to Boston P.O. [Post Office] to say 
 that Sprague is now here, came in just 
 as I got home this morning, and I am 
 concluding some arrangements to set him 
 at work. And if you will send on the 
 [Esau?] poppy, etc. I will have a drawing 
 made at once, I hope in time for your 
 purposes. Send any scraps you have that 
 will bear soaking and dissection to make
 out structure, stigmas, &c. You should 
 get this Saturday evening. If you can send 
 to New York on Monday so that the package 
 can come by Express of that evening, I shall 
 get it Tuesday. But I will say Wednesday 
 for Sprague to come up and draw it. Send 
 on any others you wish to draw, and I will 
 have them done right away. I did not reach 
 Boston until nearly eleven last night, and
