TRANSACTIONS OF THE CHICAGO ACADEMY OF SCIENCES. *— This part 
completes the first volume of ** Transactions" and in interest and value, 
and the beauty of the plates, fully maintains the high simi of the pre- 
Cr part. The plates, which are costly, are presented by the Trus- 
tees of the Academy, an evidence of their immediate interest in the 
scientific and literary reputation x their city. Nearly half of the volume 
is devoted to a biography of Robert tado the first Director of the 
ademy, from the pen of Dr. Stimpson, his successor, and the editor of

PEA of Man in North America.” Among the proofs of his great

the valley of the Somme, or the human skeleton in the nel of the Rhine; 
and although the fossil elephant (E. primigenius) existed in Europe dur-

form of the materials, and indicating a difference in the transporting 
power of the current), this association of the remains of the elephant 
with a sneer of contempt. Last spring I questioned him as to the possi-

emn and emphatic manner, that it was true." 
He describes the remains of the id builders, figuring various im-
