Prizes. 
One essay on the Walker Prize Subject for 1879, “The Structure, 
History, and Develojiment of some Cryptogamous Plant,” was 
offered the Committee on Prizes, but no award was made. The 
subject for 1880, “ The Evidence of the Extension of the Ter- 
tiary Deposits Seaward along the Coast of Massachusetts,” has ^ 
called forth no response. p 
The time for the award of the second Grand Walker Prize came 
around in 1879, and the matter was referred by the Committee to 
a special Committee composed of Prof. Win. B. Rogers, Col. 
Theodore Lyman, and Prof. George L. Goodale, who after consid- 
eration unanimously reported in favor of Dr. Joseph Leidy of 
Philadelphia, for his prolonged and valuable investigations and 
discoveries in Zoology and Paleontology. The Council accepted 
the recommendation of the Committee, and in consideration of 
the extraordinary merit of the said investigations awarded the 
sum of one thousand dollars to Dr. Leidy.
