OF THE 
PERTHSHIRE SOCIETY OF NATURAL SCIENCE. 
WINTER SESSION, 1886-87. 
nth November, 1886. 
F. Buchanan White, M.D., F.L.S., F.E.S., President, 
in the Chair. 
The following donations were intimated :— 
Museum—Perthshire Collection .—One of Don’s original specimens 
of the grass he found on Ben Lawers, and which he called Triticum 
alpinum —from Mr. John Knox, Forfar. Dried plants—from Dr. 
Buchanan White, Col. Drummond Hay, and Messrs. Wm. Barclay, 
R. H. Meldrum, and J. M‘Bryde. Log of bog oak—from the Duke 
of Athole, per Mr. J. M‘Gregor, Ladywell. Sandstone, showing 
dendroid markings—from Dr. Robertson, Errol. 
The President delivered the following Opening Address :— 
Gentlemen, —Up to last year it had not been a custom in this 
Society for the President to open the winter session by giving an 
address, and I think it may be left to the discretion of my successors 
in office whether the practice is continued or not, as possibly they 
may think it preferable to restrict themselves to the presidential 
address at the annual meeting. 
Some arguments, however, can be advanced in favour of opening 
the winter session by an address, since in it the work done by the 
Society during the past summer can be advantageously passed under 
review, work for the coming winter be suggested, and various matters 
discussed which might not perhaps be so conveniently taken up at 
any other time. 
The work of the Society in summer is of course principally in the 
way of exploration and investigation in the open air, in the gathering 
together of specimens and information, in the amassing of material 
which can be elaborated during the winter. Of the official—as they 
may be termed—excursions of the Society, reports will be found in
