Dr. Charles WacHSMUTH, the eminent authority on cri- 
noids, died at his home in Burlington, Iowa, on February 7th. 
In another place in the present issue of this journal will be 
found a sketch of the life and work of Dr. Wacbsmuth, ac- 
companied by a portrait and bibliography. The monograph 
on the camerate crinoids by Wachsniuth and Springer, now in 
press will be ready for distribution in a short time. Corres- 
pondence connected with the works of these authors may be 
addressed to Mr. Frank Springer, East Las Vegas, New Mexico*

At the meeting of the Geological Section, held on February 
17th, 1896, the following papers were presented: 
The first paper was read by Mr. L. Mel. Luquer, entitled 
■"Notes on recent Accessions of Interesting Minerals," with 
exhibitions of specimens. Mr. Luquer described in detail the 
minerals that he had recently discovered at the feldspar quar- 
ries in the northeastern part of Westchester county. They 
include uraninite. autunite, uranophane, washingtonite and 
the common minerals of pegmatite veins. He showed that 
the veins occurred in close association with an area of augen- 
gneiss, regarded as intrusive and now being studied by him- 
self and Mr. Heinrich Ries. 
The second paper was by J. F. Kemp, entitled "The Cripple 
Creek Gold Mining District of Colorado." The paper was il- 
lustrated by about thirty lantern views, most of which were 
taken by the speaker during the past summer, and by an ex- 
tensive series of rocks and ores. After a brief historical re- 
view the region was described in detail, without, however, 
introducing anything essential that is not already contained 
in the Cripple Creek Atlas folio of the United States Geolog- 
ical Survey, which was prepared by Messrs. Cross and Pen- 
rose. J. F. Kemp, Sec'y.

At the 42d meeting, held on Jan. 29th, Prof. C. E. VanHise 
spoke on "The relations of primary and secondary structures 
in rocks" being a continuation of the subject considered at the 
preceding meeting. The relation between cleavage and fissil- 
ity was discussed. It was concluded that fissility in many 
cases is controlled in its direction by a previously developed 
cleavage. Further, most rocks, at the surface having the 
property of cleavage which developed under deep seated con- 
ditions, show to a greater or less degree a fissility developed 
when they were nearer the surface. 
The relations of the secondary structures, cleavage and fis- 
sility, to bedding were considered. It was shown thai there 
is a tendency for the primary and secondary structures to be-
