angles of 55°, 65° and 70". Troilites are particularly scarce, 
but twO' or three small ones having shown on any of the 
sections made. The iron is essentially tough, although not 
more dense than in the majority of siderites. 
The specific gravity of Bacubirito is 7.69. Its analysis has 
been made by Prof. J. E. Whitfield of Philadelphia, as fol- 
lows : 
Iron 88.944 
Nickel 6.979 
Cobalt 0.21 1 
Sulphur 0.005 
Phosphorus 0.154 
Silicon Trace. 
We succeeded after a long protracted effort in detaching 
from the mass an already partly-loosened piece of about 1 r 
lbs. weight. This, polished and etched on one side, showing 
the beautiful Widmanstatten figures, has taken its place in the 
Ward-Coonley collection of meteorites now on display (on 
deposit) in the American Museum of Natural History in New 
York. 
LISTS OF FOSSILS FROM THE LOWER HALF OF 
THE CONEMAUGH FORMATION NEAR MOR- 
GANTOWN, W. VA., COLLECTED IN 1 870 
BY DR. JOHN J. STEVENSON, AND 
IDENTIFIED BY F. B. MEEK. 
I. C. White, Morgantown, W. Va. 
During the recent excursion led by the writer through the 
Coal Measures of western Pennsylvania and West Virginia, 
frequent inquiries for lists of fossils were made by members 
of the party. 
The only authentic and reliable identifications that have 
been made from the regions referred to were published by 
Dr. Jno. J. Stevenson in the 3rd Annual Report of the Board 
of Regents of the West Virginia University for the year 1870. 
As this publication is very rare and few geologists have access 
to it I have been requested to have the names of the species re- 
published. This has been done in the following lists and I have 
also appended a portion of the letter of Mr. Aleck pertinent
