Ix Science for Dec. 30, 1887, we find a description of 
Snow Hall of Natural History, at Lawrence, Kansas, accompa- 
nied by an extra sheet giving a perspective view of the building 
and floor plans of the four stories including the basement. 
Snow Hall was erected to serve as a Natural Histor}' building 
for the University of Kansas. The state Legislature appropriated 
fifty thousand dollars for the purjDose in 1SS5; and the building 
was completed, formallv named and dedicated on Nov. i6th, 
1886. The name is given in honor of the venerable professor 
F. H. Snow whose connection with the University dates from 
its foundation in 1866. 
The building seems particularly well adapted to the purpose 
for which it was designed. In the basement is a large labora- 
tory for elementary botany, a taxidermist''s workshop, a biolog- 
ical laboratory-, and rooms for storage and other purposes. 
The geological collections are displayed in a large museum 
on the first floor, and on the same floor conveniently situated 
with reference to the museum are the geological laborator}-, 
and a workroom for the curator of geology. The general lec- 
ture room is on the same floor. 
The second floor contains separate rooms for the entomologi- 
cal, general zoological and botanical collections, together with 
appropriate zoological and botanical laboratories and work- 
rooms. On the third floor there are anatomical and photograph- 
ical laboratories, an anatomical museum, store rooms and an 
osteological workroom for the preparation of material. Kansas 
University is to be congratulated on her splendid equipment for 
carrying on work in geology and natural history. 
Three or four years ago the quarrymen at Le Grand, 
Marshall Co., Iowa, exposed a thin layer that in places is 
crowded full of interesting and most beautiful crinoids. The 
quarries are opened in the Kinderhook limestone, the lower 
part of the Subcarboniferous formation, and have been worked 
for a great many years. The crinoids occur in a bed of calca- 
reous shale and are in a most perfect state of preservation. 
The locality has furnished eighteen new species of crinoids and 
two of blastoids. These have all been described by Wachsmuth 
and vSpringer, and the descriptions and illustrations will be 
published in the forthcoming eighth volume of the Illinois 
geological reports. 
The American Naturalist, a monthly Journal de- 
voted to Natural History and travel, and an old favorite with 
working naturalists everywhere, will be published during 1S88
