S. JEFFERSON'S VALEDICTORY ADDRESS.

thé Crprea Europea from the Ferne Islands. This is the only 
specimen of the cowry genus found in England, though the species 
are abundant in the tropics. 
Those who were present when Mr. F. Greenwood exhibited 
the series of beautifui dissections of the common black slug 
(Arion ater) will not readily forget how magnificently all the 
details of the muscular, nervous and vascular tissues were brought 
out. Coupled with full and clear explanations kindly given by the 
exhibitor, these cbjects were not only full of beauty but most 
instructive. 
In entomology, Mr. Grassham and others have contributed 
very many specimens. Quite a windfall befell this section in the 
flight of locusts to which cur attention has been drawn during the 
last year. 
The ornithologists have also contributed their share. Mr. 
W. H. Hay excited great satisfaction by the series of the eggs of 
twenty-seven species of birds, all of which had been collected by 
himself within a radius of about a dozen miles from this town. 
Among other interesting local gatherings was one by Mr. E. E, 
Prince, who brought three members of that species of the newt 
family known as Lophinus palmatus. This diffeis from the com- 
mon newt in the fact that its hind feet are webbed or palmated. 
It is believed that this is the first recognition of its occurrence in 
this locality. 
We must not forget the very lively dormouse which Mr. Grass- 
ham captured in the Meanwood valley, and which was exh.bited 
last May. Members will not forget that a former exhibition of 
the same creature from the same neighborhood was made a year 
or two ago by the Rev. J. Hanson. 
In botany Mr. F. Amold Lees has contributed again and again 
objects of interest. Among others the Cypripedium Calceolus, the 
extremely rare “‘lady’s slipper” orchid from Durham. Also from 
Upper Teesdale Cystoptert: alpina, the Alpine bladder fern, which 
Mr. Backhouse, junr, first showed to be a native of Britain in 
1873. From the N.W. of Thorparch he also exhibited Anthemis 
tinctoria and Alyssum incanum, neither of which had before been 
- discovered in Yorkshire. Mr. Scholefield has also fiom time to 
time brought interesting plants, as other members have likewise 
_ done. 
In geology and mineralogy various members have from time to 
time supplied the tables with examples. Mr. G. A. Kennedy 
brought a fine example of the fossil tooth of Ahizodus Hiberti, a 
ganoid fish from the upper coal measures,
