REPORT OF THE 
Geology. —The Honorary Curator reports that no opportu¬ 
nity of purchasing fossils required for the Yorkshire Collection 
has occurred during the past year. The income derived from 
the Reed Fund has again been spent in the purchase and 
binding of books. Donations of fossils have been received 
from Mr. Cotsworth and Dr. McLeod. 
Ornithology. —The re-arrangement of the Bird Collections 
has been pushed forward as quickly as circumstances would 
allow, and the cases in the room formerl}- occupied by the 
Foreign Bird Collection, as well as the gallery overhead, are 
now being filled with British species. The foreign birds being 
in a deplorable condition have been weeded out, and the best 
specimens have been cleaned and put temporarily into the 
Rudston Room where they will be grouped according to their 
geographical distribution. In the work of cleaning referred to 
above, we have to thank Mr. Oxley Grabham, of Thornton 
Dale, for many hours of valuable help. Among the presenta¬ 
tions of the past year, one of the most noteworthy is a hybrid 
crow from North Wales (corvus covvus x crovus covnix). 
Mineralogy. —During the past year the additions made to 
the collections have been (i) a specimen of Calcite from the 
Scordale Barytes Mine, presented by Mr. J. Backhouse ; (ii) a 
small collection of rocks and minerals got together by the late 
Professor Piazzi Smyth, and purchased by the Society. The 
collections are in good order. 
Meteorology. —Statistics of Station : Longtitude i° 5' W.; 
Latitude 53 0 57' N. ; height above mean sea level r 56 feet. 
1900 has been a typical year in all respects. 
Temperature showed a rather greater range than the previous 
year, and the mean annual temperature is slightly lower, being 
48*6 as against 48*9. The lowest temperature was recorded 
on February 13th, when 12° F. was registered, and the highest 
on July nth, when the reading was 87° F., the range for the
