REPORT OF THE 
The Zoological collections, likewise, have remained almost 
without increase. The general collection of Birds was, how¬ 
ever, removed from the cases, and carefully cleaned by Mr. 
Baines, in the course of last spring, when the cases were also 
cleaned, repaired, and newly whitewashed, and the collection 
now presents a most satisfactory appearance. The Mammalian 
Skeletons, in the Gallery of Comparative Anatomy, were also 
cleaned and rearranged, so as to bring them as nearly as 
possible into accordance with the classification. 
The Curator of British Ornithology has introduced a few 
specimens of young birds into the collection during the year 
1860, and hopes that he may hereafter be able to add consider¬ 
ably to their number; the study of the immature plumage of 
birds, as contrasted with their adult condition, being at once 
interesting and instructive. 
The Curator of Meteorological Instruments reports, that 
the mean temperature of York for the year 1860 is 46*45°, 
being one degree and one tenth below a mean of twenty years. 
Three months of the year were above a mean, viz., January, 
May, and October. December, the coldest month of 1860, was 
5° below a mean of twenty years ; February below. The 
remaining seven months were about one degree each below. 
July was the warmest month of 1860, and was within fo of a 
degree up to the mean of twenty years. On the morning of 
the 25th December the Thermometer registered 4° below Zero, 
the lowest temperature registered in York during the last 
thirty years. The highest registration for the year was 73*5°, 
on the 5th May and the 7th July, making the range of the 
Thermometer 77*5 degrees for the year. 
Within the last thirty years, the following have had a 
temperature below that of 1860, viz.: — 
1856 .... 46*0 
1855 .... 44*4 
1853 .... 45-9 
1838 .... 45*8 
The highest mean temperature during the thirty years was 
50*2°, in 1834; 50*2° — 44*4° = 5*8°, as the range of annual 
temperature in that period. The following exhibits the tern-
