General Kane resumed the reading of his paper on the ethnological 
movements taking place in Northern Mexico. Professor Cope exhibited 
and described fragments of the fossilized skeleton of a gigantic Dino- 
saurian, found by Prof. J. S. Newberry, in Painted Cañon in southeastern 
tah, when acting as geologist to the expedition across New Mexico to 
the Junction of the Green and Grand rivers under Captain McComb, 
U.S. This fossil was derived from supposed Triassic beds, and was 
named Dystropheus viemale. Professor Cope exhibited drawings of 
supposed Indian sculptures in the form of a dial or zodiac, said to have 
been recently discovered near Davenport, Iowa, in an Indian mound. 
March 2, 1877. — Professor Cope exhibited the fossil skeletons of two 
species of Hlasmosaurus from the cretaceous formations of the West. 
ne of these measuring thirty-five feet in length, from the Niobrara 
Cretaceous of Nebraska, was regarded as representing a new species and 
was called Æ. serpentinus. The other, represented by seventy-six ver- 
tebra from the Fort Pierre group of Montana, was identified with the 
E. orientalis, of New Jersey. Professor Cope read a description of a 
new form of Proboscidian allied to Dinotherium and Mastodon, which 
he called Cenobasileus tremontigerus.

Professor Cope exhibited the cast of the brain cavity of the Coryphodon 
elephantopus from the Wasatch Eocene of New Mexico, derived from the 
collections made by Lieut. G. M. Wheeler, U. S. A., and described its 
characters, which led him to the conclusion that the Amblypoda should 
be referred with the Bunotheria to a distinct sub-class of the Mammalia, 
which he called the Protencephala. He stated that the brains of the 
following genera conformed to this type: Coryphodon, Uintatherium, 
Oxyena, Aretocyon.

arll and Mansfield. 
April 20, 1877. — Mr. Britton read a paper on the value of pressed 
peat as an article of fuel. Professor Frazer presented a paper on the 
cause of the northwest dip of the Mesozoic rocks in Eastern Pennsyl- 
vania, and on the origin of the magnetic and specular iron ore banks in 
the Mesozoic and Azoic rocks of the same region. 
May 4, 1877. — Professor Cope read a paper on the structure of the 
in in Procamelus as derived from a cast of the cavity of a skull ob-
