The Secretary read an imperfect list of fossils collected by 
Mr. C. E. Hall, Paleeontologist of the Survey of Pennsylva- 
nia, at Harvey’s Five Points, in Westmoreland county, Pa., 
from a horizon in the Lower Barren Coal Measures, about 
300’ below the Pittsburgh Coal and therefore about 2000 
feet above the supposed or presumptive top of the Chemung 
Formation, one of which appears to be Streptorhyncus Che- 
mungensis, var. arctostriatus of the Chemung Group in the 
State of New York (see N. Y. Pal. Vol. IV. p. 71), and 
another, Ambocelia umbonata, var. gregaria, does not seem to 
differ from that found in the Chemung of New York, yet 
occurs here in great numbers, and in some cases composes 
almost the whole mass of the rock. These fossils are 
accompanied by a Streptelasma too imperfect to be specified, 
and by undetermined species of Chonetes, Productus, Athyris 
and Cardiomorpha.* 
Professor Frazer made some preliminary remarks upon a 
hitherto unnoticed trap dyke extending for miles through 
Lancaster county, in Pennsylvania, into or towards the 
Welsh Mountain. Its importance arises from the fact that 
it passes through the Nickel Mine, and through the North 
Valley Hill, of assumed Potsdam sandstone. 
Pending nominations Nos. 840, 841, 842 and new nomina- 
tions Nos. 843, 844, 845, 846, 847, 848, 849 and 850 were 
read. 
An application for the Coal-slack Premium from John 
R. Peters, M. E., of Dover, Morris Co. N.J., was received 
through Mr. Briggs, and referred to the Committee on that 
subject. 
A form of advertisement suggested by Mr. Fraley to the 
Secretaries was referred to their consideration. 
Mr. Briggs, who objected to certain expressions, moved 
the following resolution, which was referred to the Board of 
Officers, after the word “approved” had been struck out 
with the consent of the mover.
