its relationships. It has been suggested humorously that the animal 
should be named Bryopithecus after the most distinguished Primate which 
the State of Nebraska has thus far produced. It is certainly singular that 
this discovery is announced within six weeks of the day (March 5, 1922) 
that the author advised William Jennings Bryan to consult a certain 
passage in the Book of Job, "Speak to the earth and it shall teach thee," 
and it is a remarkable coincidence that the first earth to speak on this sub- 
ject is the sandy earth of the Middle Pliocene Snake Creek deposits of 
western Nebraska. 
The geologic age of these two Primate teeth is now believed to be the 
same as that of Thousand Creek, Nevada, and Rattlesnake, Oregon, among 
the fauna of which Pliohippus is very abundant and varied; it also con- 
tains Ilingoceras and other strepsicerine antelopes of Asiatic affinity; 
it is the last American fauna in which occurred the rhinoceros, preceding 
the Blanco fauna in which the Asiatic brevirostrine M. mirificus first 
occurs.

RECENT DISCOVERIES ON THE ANTIQUITY OF MAN

Read before the Academy, April 25, 1922 
This paper is an abstract of two lines of research recently undertaken by 
the authors which will be published under the titles : Old and New Standards 
of Pleistocene Division in Relation to the Prehistory of Man in Europe 
Pliocene {Tertiary) and Early Pleistocene {Quaternary) Mammalia of 
East Anglia, Great Britain, in Relation to the Appearance of Man.^"^ 
At the April, 1921, meeting of the National Academy, Dr. Osborn 
ventured the prediction that a large-brained type of man would be found 
in the Pliocene. He was not aware that such a discovery had actually 
been made in the Upper Pliocene Red Crag deposits near Ipswich, England, 
by J. Reid Moir; in fact, Mr. Moir's discovery of Red Crag and of sub- 
Red Crag man was not accepted in England, and it was not until an un- 
mistakable human industrial level was found at Foxhall, near Ipswich, in 
the summer of 1921, that this locality was visited by the French archaeolo- 
gist Breuil, who announced this important discovery at the Archaeological 
Congress at Li^ge, in August, 1921. Dr. Osborn immediately planned
