the world. The first things sent from Para were 

 slabs rather than truncheons of wood (all ordinary 

 exogenes), but I am promised palm stems and 

 woody climbers, of which I shall take a portion to 

 build up our general Natural History Museum at 

 Cambridge, which with the zeal of Agassiz and Wy-

 you. If you will send me a few duplicates of your 

 circular, I will have them placed in proper hands 

 where they may turn to good account. I am de-

 which I had also heard last summer from Mrs. Mc- 

 Gilvray. I owe him a letter, but it is too late to send 

 my congratulations, now that he is probably far on 

 the way to India. I admire his zeal and energy, and 

 wish him an excellent time and a prosperous return. 

 The government has behaved most handsomely in 

 affording him such important aid in his undertaking. 



Proper specimens of maple sugar will keep per- 

 fectly well if placed in a glass jar with a closed cover. 

 I will surely send some in the spring.

 collection, and a set of Fendler's from Santa FC*, up 

 to Rosaceae. The specimens are perfectly charming ! 

 so well made, so full and perfect. Better never were 

 made. In a week I shall take them right up to study, 

 and they are Rocky Mountain forms of vegetation en- 

 tirely, so I can do it with ease and comfort. It is a
