A FURTHER REPORT ON THE ANATOMY OF 
THE ELEPHANT'S EAR. 
By Huntington Richards, M. D., New Vork, N. T. 
When Doctor Buck committed to me a continuance of 
the dissection and description of the larger one of the two 
anatomical specimens discussed in his papers entitled "A 
Contribution to the Anatomy of the Elephant's Ear" and 
"A Revised Description of the Anatomy of the Elephant's 
Ear," he had obtained from Prof. Wilder his consent to the 
removal of certain restrictions in regard to destruction of 
the specimen as a museum preparation, which had greatly 
hampered him in his work. These restrictions had handi- 
capped him. Through his kind stipulation I was freed from 
this handicap at the very beginning of mv further investiga- 
tions, and, in consequence, very soon made a discovery 
leading to the necessary revision of the doctor's first paper 
in the second just presented to the Society for publication in 
this year's annual Report. The outer surface of the speci- 
men up to the moment of this discovery had been believed 
by Dr. Buck and myself to be also its lower surface and a 
part of the lateral aspect of the elephant's head, — a belief 
confirmed by the assumed direction of the Eustachian tube, 
and unshaken by any information provided (for none was 
given) regarding the direction of the planes of section 
made at Cornell University. This surface was covered by 
a layer of very dense, tough, leather-like tissue (muscle- 
stumps, fibrous tissue, fat, etc.), hardened by prolonged 
immersion in alcohol, which layer effectually masked all 
inequalities of surface existing in the underlying bone. Its
