55 species, 30 of wliicli had anticipated their ordinary time of 

 flowering from one to three months. The forest trees, as a rule, 

 were about eight weeks earlier than usual. 



Mr Edward A. Wiinsch exhibited very large and finely preserved 

 specimens of Feden maximus, from the glacial clay-beds at Fairlie. 

 These shells were found at a depth of about two feet from the 

 surface, and were disposed so regularly that it seemed evident 

 they must have lived and died in the position in which they lay. 

 Mr David Eobertson, F.G.S., and Mr John Young, F.G.S., made 

 some remarks regarding the Fairlie beds.

On a Visit to the Marine Fish-pond at Fort Logan, Wigtonshire. 



By Mr E. A. WuNSCH. 



This pond, which is situated on the property of James M'Douall, 

 Esq., of Logan House, a distance of fourteen miles from Stranraer, 

 has acquired a certain celebrity for its tame cod fish. Finding 

 myself recently in the neighbourhood, with a day to spare, I 

 visited the pond; and I thought that an account of my visit, from 

 the geological, as well as from the natural history and economic 

 point of view, might not prove uninteresting to the members of 

 this Society. 



After holding on in a south-westerly direction, leaving the bay 

 of Luce on your left, and emerging from a drive through the 

 beautiful private grounds of Logan House, you suddenly come 

 upon one of the roughest and wildest spots on the shores of the 

 Mull of Galloway. The schistose rocks of the district, tilted up 

 all but vertically, with very distinctly stratified beds of various 

 degrees of hardness, present their upturned edges to the action of 

 the sea, giving rise to an endless variety of small bays, narrow 

 gorges, gullies, and fissures, into which the waters rush furiously 

 in stormy weather. One of these openings into the solid rock, 

 naturally excavated by the tides and waves, and afterwards 

 artificially enlarged and improved, has been converted into the 

 pond now tenanted by the tame fish. 



The pond is about 20 feet in diameter, and 12 feet deep, well 

 enclosed on all sides by the natural rock, to the height of about 

 10 feet, and further built round with a circular wall about 7 feet 

 in height. There is also a shelf, about 2 feet wide, at the water- 

 level, enabling you to walk all round the pond. The channel by
