          work like a dog, to get thru. [through] Japan
 Collection, & read a paper on Tuesday 
 at a social meaning of Academy at 
 Mr. Loring's house that evening (Jany. [January] 
 11th). Now come on (if by day
 train, stop there, 8 Ashburton Place, 
 where I will be. 


 I am going to hold forth for 
 nearly an hour, upon Japan Botany 
 in its relation to ours & the rest of 
 the northern temp. [temperate] zone, and 
 knock out the underpinning of Agassiz'
 theories about species & their origin, 
 show, from the very facts that 
 stumbled De Candolle the high 
 probability of single & local creation 
 of species, turning some of Agassiz'
 own guns against him. 


 I introduceed it here at Club, 
 last month, & Agassiz took it very 
 well, indeed. I shall not have time to 
 look at the rest of Hayden's plants, 
 till next week, so I send you this envelope, 
 tho. [though] I forget what it contains. You 
 will see.
