The President delivered the following Opening Address :— 
Gentlemen.—A nother revolving year Jias brought round the 
day on which we once more gather in this room to hear what has 
been done by the Society since we last met together. Your delegates 
to the British Association for the Advancement of Science and to the 
East of Scotland Union of Naturalists’ Societies will presently render 
an account of their stewardships; to me falls the duty of giving 
a report of the field work accomplished in our beloved Perthshire. 
As in former years, the number of excursions made exceeded 
those set forth in the programme prepared in spring, and, though in 
previous addresses I have taken what may be called the official 
excursions first, to-night I think it will be better to describe our 
explorations in their chronological order. I may, first of all, remark, 
that on the whole there was a better attendance at the excursions 
than there has been during the past few years. 
As usual, the first excursion was on the Queen’s Birthday 
(21st May). Starting from Perth Bridge, we followed the Muirhall 
Road for about a mile and a half, and then followed the path which 
leads through the woods on the left side of the road. On the side of 
the road, about a mile from Perth, there is a small colony of 
Geranium pyrenaicum , which seems to be increasing. In the wood 
we inspected a thicket of Prunus insititia , which was in fine flower. 
We also found some curious hybrids between the primrose and the
