occurring near Strathmiglo^ and the Malva moschata, Dianthus 

 deltoides, Geranium phaum, Scrophularia vernalis, Lychnis Vis- 

 caria, and Cystopteris fragilis, all of which, though comparatively- 

 rare in the neighbourhood of Edinburgh, were found abundantly 

 in Glen Farg. Specimens of the plants were exhibited, and Mr. 

 Sadler at the same time presented to the herbarium a collection 

 of Lichens and Mosses made by him on the Breadalbane moun- 

 tains in August last. He also exhibited a collection of Lichens 

 which had been collected by William Murray, Esq., in California, 

 and remarked that it was somewhat singular that they were all 

 British species except one, and the most of them common to 

 Scotland. Mr. Sadler also exhibited a remarkable specimen of 

 a Fungus, growing between two plates of glass. After the trans- 

 action of some business the Society adjourned till March 20th.
