TO CHARLES DARWLN". 



CAMBRIDGE, June 10, 1877.

 bring forth good fruit. I cannot blame him if his 

 modesty and caution have kept him back from publi- 

 cation as yet, but he has time before him, and even a 

 sight of you will be a stimulus to his ambition as well

 of any good do. He has just married the daughter 

 of my dear old friend, the late Mr. Sullivant, who 

 did for muscology in this country more than one 

 man is likely ever to do again. The young lady is 

 very dear to your good friend Mrs. Gray and to me ; 

 and, as you have more than once made a remark com-
