176 SPENCER FULLERTON BAIRD 
why I deemed it different from C. Cognatus, but I was aware of this 
species being described by Richardson. 
I am a subscriber to the Royal Society since last year. I have 
only the Vol. of reports and that on alternation of generations which 
I should not have got, they belonging to a different year from 1847 
in which I entered. 
If you get so many Menopoma allegheniensis you had better 
send some of them to Leidy for anatomization, i.e. if his hands are 
not already too full. One has been taken as low down in the Sus- 
quehanna as Middletown or Conewago. You “have a new Sala- 
mander.” So have I. 
It would not “be too great a stretch” of anything for you to 
borrow, and me to lend, Cuvier’s Régne Animal, new edition, and 
you shall have the fish and reptiles as long as they will be useful to 
you. I am not now studying these branches, so that the books are 
so much lost capital, unless you will make them work for their main- 
tenance. These portions of this fine edition are complete. I have 
parted with the birds to Liebhart and the shells to Phillips, the balance 
of the entire work I have. 
As to borrowing the works you mention in return, I may state 
that to me mineralogy is “stony ground” and I wouldn’t willingly 
deprive you of the ability to make constant references to a work 
rich in observations on our local fauna and which so dichotomously 
arranges animals (horses, ducks, and cows, for example) into tame 
and wild. 
Let me always hear from you whenever you think I can aid 
you in anything for I want our work to be done and am not anxious 
to monopolize. 
Dr. Schaum, an excellent German entomologist, is in N. Y., 
and he goes to N. Orleans, thence up the Arkansas as far as he can, 
and home again next July. I talk of going South-west next summer. 
Yours, StEHMAN HaLpEMaN. 
On the 17th of December Rev. Dr. Wheeler, President 
of the University of Vermont, came to offer Baird the 
chair of Chemistry and Natural History at Burlington 
at a salary of $800.00 a year.
