great and your science too, to accomplish all you have done. I wish 
you all success and would be glad to do more than wish.

My pear S1r,— 
I have received your box in perfect good state, and return my 
best thanks for all the fine things sent to me, which are equally 
instructive and acceptable. The Lepidostei are particularly welcome. 
I trust I shall be able to prepare a good paper upon them now. 
I have written to-day to Prof. Henry about the Conservatorship 
of the Museum in such terms as to let him feel how important your 
connection with that Institution might be for its advance in the 
Nat. Hist. Department. 
Girard says the Southern Cottus is again a new one. I have not 
yet compared it myself. 
I send two new plates for your revision and the names. Please 
return them soon as Mr. Sonrel is anxious to have them printed while 
the press man is not too busy and can take good care of them. What 
is the number to be struck off? I think Prof. Henry said 1,000 for 
the volume and 250 for us. You need not return the proofs, but 
only send your remarks. Mr. Garrigue will have already written 
to you that it will give me great pleasure to revise any part of your 
translation of the Cyclopedia you may wish to send to me, and I 
will do it always in as short a time as it can possibly be done. 
It has given me great pleasure to peruse your Batrachians. I 
shall not fail to send a copy to Tschudi and though I do not know 
where he is at present, I shall include it to a friend who must know 
his whereabouts. 
From Spencer F. Baird to Prof. Joseph Henry.

busy this fall between your gigantic plans for the advancement of
