XT, 32.] TO MRS. TORREY. 305 
TO GEORGE ENGELMANN. 
CAMBRIDGE, 22d June, 1843. 
When you get sufficient collections from any of 
these botanists for distribution, you will please forward 
me a set, with your own critical remarks. Although 
I excessively dislike to study special collections far 
ahead of my work, yet in these cases it will be impor- 
tant, and I will consent to do it. If I thus join in 
the responsibility and labor, which will be great to a 
person with his hands so full as mine, the articles 
written on the subject and the new species must bear 
our joint names. 
You cannot have failed to perceive nee the genus 
Astragalus is not well done in the “ Flora.’ 
I agree with you generally in the a aeuty of 
too much multiplying names of species after the col- 
lectors, ete., yet I think these are good names, easily 
remembered, and particularly advisable in very large 
genera. My practical rule is to name such species 
after the discoverer, etc., if I cannot find any really 
pertinent characteristic name unoccupied. . 
There is much to be done, and so little Buia that I 
often wish I could divide myself into a dozen men, 
and thus get on faster. Let us, however, take partic- 
ular pains to do everything thoroughly as far as we go. 
TO MRS. TORREY.

I find Cambridge, in vacation, as quiet as possible, 
—most people away. The president’s family were 
at home, and unaffectedly glad to see me ; but several 
of them, including Miss Susan, who makes drawings 
for me, are about to set out on Monday for Lake 
Champlain, Montreal, and Quebec; to be absent
