TO CHARLES DARWIN. 
CaMBRIDGE, June 10, 1877. 
My pear Mr. Darwin, — Except when you are 
to be aided in your work I decline to give letters of 
introduction to you, knowing how you are occupied 
and how infirm your health at any time may be. So 
please take this note to mean just this. The happy 
couple who bear it would be delighted to call some 
day, if you say so, and pay their respects to you, and 
I will tell you why I am disposed to promote their 
wishes. 
Mr. Burgess! was a favorite pupil of mine, and is 
a young naturalist of much promise ; not in my de- 
partment, however, but in entomology. He takes par- 
ticularly to the anatomy of insects, draws capitally, 
and shows talent for research, which we trust will 
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 
as something to remember in after years. I need not 
say that he takes to Evolution ; all young naturalists 
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- 
1 The afterwards famous designer of yachts.
