Dr. Hawkins’ work and of allowing him to extend the very instruc- 
tive series which he had planned. Not only does it devolve on — 
the Commissioners to render justice to Dr. Hawkins, but also, by 
the restoration of the work and the reinstatement of Dr. Hawkins, 
to remove a blot from the fair fame of American science. 
It seems as if the interference with the work of scientific men and 
their snubbing by the “ Heads of Departments ” had been epidemic 
of late, for not only have we to regret the treatment of Dr. Hawkins 
and Dr. Parry in this country, but also the equally outrageous 
treatment of Dr. Hooker by the Head Commissioner of the Kew 
Gardens in England, as lately made public in “ Nature. ” Are 
we really going back to the early days of science, when a scientific 
man was looked upon as a subject for the mad house, or is it owing 
to the fact that ‘* brains are scarce in high places?” i 
We take this occasion to correct an impression which we find is 
held by some of our readers relative to the American Museum of 
Natural History, which is supposed by many persons not acquainted 
with the complex system of the Central Park, to be under the 
same government as that which Mr. Hilton represented, and that 
its officers were in a measure responsible for the outrage perpe- 
trated. Such is not the case, and we should feel grea 
any remarks of ours had been construed to the disadvantage of 
that institution, which we believe to be doing. good work an 
worthy of all assistance from scientists throughout the country-
