          Cambridge, Saturday Eveng [Evening]


 My Dear Friend 


 The 11th lecture is off. The last 
 must be entirely prepared on Monday & Tuesday; and 
 I have besides to begin with my freshmen on Monday. 


 A pleasant letter from DeCandolle [De Candolle] arrived to-day 
 just as I was despatching some seeds to him, 
 and a copy of the Bot [Botanical] Text Book. (Prodr. [Prodromus] vol. IX
 is on the way hither) I shall send you probably 
 on Monday, to W&P [Wiley and Putnam] the volume of Delessert,
 and a copy of Bot. T.B. [Botanical Text Book], it is not to be published 
 for some little time, tho' I am to use it is at Cambridge. 


 Old seeds of Skunk Cabbage are germinating 
 finely in the garden, and I am also studying its 
 ovology & the whole formation of its embryo. 


 Sprague came up, has made a hasty 
 colored drawing of Illicium for you, and has 
 taken it home to copy. I will send it on next week. 


 We should like to know at once whether 
 you will engage Sprague to make the drawings
 we spoke of, under my direction, that we may 
 make arrangements accordingly. 


 Sprague must do our Bot. [Botanical] drawings, and Prestele
 cut on stone, I have written to the latter, about price 
 &c.
