cordial support and co-operation. This being my view of the act of 
Congress, I shall protest against any interference with my preroga- 
tives, and refuse to employ any person whom I think will not render 
me cordial assistance in carrying out the plans which I deem the best 
for the interests of the Institution. The assistants are responsible 
to the Secretary and the Secretary to the Regents; hence, all com- 
munications intended for the Regents or the Public must pass through 
his hands. These restrictions I am convinced are for the good of the 
whole and nothing would tend sooner to destroy the usefulness of 
the institution than the division of it into a number of separate 
interests. The whole establishment must be a unit and the effort 
of every one connected with it must be directed to the development 
of every part of the plan. I shall therefore expect of you not only 
assistance in the way of taking charge of the collections in Natural 
History, but also in the publications—the correspondence and other 
business. On the other hand, I will furnish you with every facility 
in my power, compatible with the interests of the institution, for 
the promotion of your own studies, and shall in all cases consider 
your reputation as identified with that of the Institution. 
I do not apprehend any difficulty between us, but just now, from 
the difficulties I have had to contend with in regard to the building 
etc., I am disposed to move with caution as to the future. 
I think the Board will be disposed to allow me more assistance 
as soon as I shall signify my desire for it; and if you have not changed 
your mind I am disposed to have you brought in as soon as you can 
come. Let me hear from you as soon as convenient, and believe me 
as ever, 
Your friend, etc., 
JosepH Henry.
