The death of Eli K. Price, senior Vice President of the 
Society, at his residence, in South 15th street, Philadelphia, on 
the 11th inst., in the 88th year of his age (born July 20, 1797), 
was announced, 
The following contributions to the Society were read:

Wise, Smyth, and Washington counties, of Virginia, by John

J. Stevenson, Professor of Geology in the University of New 
York, with seven cross sections and a geological map. 
Mr, Lesley remarked that— 
This memoir was a continuation of Prof. Stevenson’s description of the 
Geology of Southwestern Virginia, read before the Society, August 20, 
1880, January 21, 1881, and October 7, 1881; but without further reference 
to the economies of the region. 
The absence of the Chemung and Portage and Genesee formations VIII 
f, ¢, d, from long outcrops in Lee, Wise and part of Scott counties (although 
the Chemung is present on Indian creek, &c. further east) ; the absence of 
the coarser members of the Hamilton VIII ¢, and the Marcellus VIII 8,

berg VIII a, Oriskany VII, Lower Helderberg VI, and Onondaga V d— 
leaving merely the Clinton V a, and Medina IV 4, c, which, however, thin 
out and disappear themselves, but dn a southeasterly direction—are facts of 
importance to the proper understanding of the original source, or rather 
sources of our Paleozoic deposits. 
The logical discussion of facts relating to the anomalous salt and gyp- 
sum deposits along the Holston, at Saltville and elsewhere, is speciaily 
valuable. The independence of the gypsum clays as regards the Paleozoic 
floor-rocks on which they rest, and the evident erosion of the gypsum 
before the deposit of the blue clay, upon which again the Mastodon con- 
glomerate lies, are important steps of an argument resulting in a theory
