292 The American Geologist April, 1897 
'JMie second paper of the evening was by Prof. R. E. Dodge 
entitled "Recent work in Phj'siography," 
Prtjfespor D()dfi:e gave an outline of De Lapparent's "Legons en Geo- 
graphic Physique,"' of Sir John Bullock's ''Scenery of Switzerland," 
and of two recent papers, one by M. R. Campbell, entitled "Drainage 
Modifications and their Interpretation," the other by C. F. Marbut on 
"The Physical Features of xMissouri." 
The last paper of the evening was by A. A. Jiilien on the 
" Sculpture and Sorting of Sands." 
The speaker, by means of lantern slides, illustrated various varieties 
of sand, and their chief methods of origin and their compositions. After 
citing the schemes for the classification of sands advanced by Zirkel 
and Daubree, he gave one of his own, .which was more elaborate and 
was partly based on the methods of origin and partly on the physical 
characters.

llarch 15, 1897. The first communication of the evening 
was by Mr. Ileinrich Ries entitled " Mineralogical Notes." 
Mr. Ries spoke of some allanite ci'ystals with new faces; also of some 
large crystals of fibrous gyijsum from Newcastle, Wyoming: also exhib- 
ited some large childrenite crystals from Maine and some amphibole 
crystals with many terminal faces from Virginia. He also spoke of some 
pseudomorphs of gold after sylvenite from Cripple Creek, Colorado. 
The finding of a new beryl crystal with an unusually large number of 
terminal faces in New York city was also noted, 
The second paper of the evening was written by Mr. Her- 
bert Bolton, entitled "The Lancashire Coal Field of England," 
and read in abstract by president Stevenson. 
The paper spoke of the geographic conditions of the Lancashire coal 
field and its neighborhood, of the extent and quality of the coal and of 
the age of the structural movements which had caused the present geo- 
logical characteristics in the coal area. A careful correlation was made 
between the coal measures of this field and the deposits of the United 
States. Distribution of the fanua and flora and their character was 
taken up in some detail and it was shown that in the lower coal meas- 
ures the life is mostly marine, in the middle coal measures of fresh and 
brackish origin, and in the upper coal measures that the fauna was 
scarce. When published this paper will be a valuable contribution to 
the literature of coals and will Vje of great assistance to workers in 
America in their endeavors to correlate the deposits on the two sides 
of the water. 
The third paper of the evening was by Stuart Weller, of 
Chicago University, entitled " The Batesville Sandstone of 
Arkansas," abstracted by Mr. Gilbert Van Ingen. 
The paper entered into some detail regarding the Batesville section 
and the fauna of the Batesville sandstone in that section. Of the inver- 
tebrates thirty species have been found, of which eleven poiiit to the St. 
Louis age of the sandstone, six to the Kaskaskia age, while thirteen are 
of indeterminate value. On account of the greater abundance of the 
numbers of specimens of the second group and from stratigTaphic evi- 
dence as well, it is probable that the sandstone belongs in the base of 
the Kaskaskia group and is the same as the Aux Vasa limestone of 
southern Illinois. This paper gives the data wherewith to correlate the 
Mississippi section with the section about the Ozark hills.
