New York State Museum, Bulletin 99. 
Quadrangle. By D. D. LUTHER, 
map. 
Geologic Map of the Buffalo 
1906. Pp. 29 and geologic 
This bulletin is the latest one, prepared under the direction of Dr. John 
M. Clarke and published by the New York State Museum, devoted to 
the mapping and description of the geologic formations of a quadrangle. 
As is customary with this series of bulletins, it contains a map on which the 
areal distribution of the various formations is shown, accompanied by a 
text giving an account of their occurrence and characters together with lists 
of their common and diagnostic fossils. As stated by Dr. Clarke, “students 
of geology in Buffalo will find the map and its accompanying text a detailed 
guide to the rock sections of the region and to the scattered and often obscure 
outcrops of the formations, and, since this is the second largest city in the 
state, the bulletin will be of special service to a large number of people. 
The strata composing the surface rocks of this quadrangle have an 
aggregate thickness of over 800 feet and are of Devonian age, with the
