Dear Engelmann, 
"tty thanks for your kind letter which I received 
Just now and answer immediately, because day after tomorrow I 
shall leave Cambridge for some time to give lectures and thus 
could a the time probably for a few weeks to write. I 
look forward with great pleasure to get the fish and shall 
most likely compose a list of the fishes of your State for 
the July number of the American Journal, similar but more 
complete as the one for Tennessee, which I shall send to you 
in a few days and of which several copies will follow for dis. 
tribution.I will send it directly to the people who'se addresses 
you have given me. I have already classified all of Stolley’s, 
as well as those brousht along by myself, and will have little 
to do to inteerate those to be received from you. I expect day- 
1y-tueal barrels from Stolley. I will gladly erase his debt 
with you, but, please, permit me that I wait for the harvest at 
the completion of the lectures,.. 
As I delayed the publishing of the special sections 
as far as this is possible with american forms, .I would much 
appreclate if you would send to me at least certain duplicates 
of items you mailed to Baird, so that I ee with all 
parts of the zoology of the West. Don't you have anybody who 
could collect butterflies and other insects there. Has’nt 
Georg started to get pleasure from this ?
