The rocks at their head are not very extensive, but seemed 

 worthy of fuller exploration. The most conspicuous plants were 

 Dryas octopetola, L., Bartsia alpina, L., and Salix lapponum, L., 

 which generally indicate the presence of a rich alpine flora. 

 Carex vaginata, Tausch, and C. capillaris, L., were abundant, 

 with a few species of Poa ; but P. alpina, L., which is usually 

 common in such places, was not seen. Beinn Doireann was also 

 visited, but proved to be comparatively barren. 



Mr. Richard M 'Kay repoi'ted on an Excursion made to Troon on 

 26th Jiily. Ooodyera repens, R. Br., was observed in Fullarton 

 Woods, near the railway station ; and on the ballast-bank 

 numerous plants were found, including Diplotaxis muralis, DC, 

 Senehiera didyma, Pers., S. Coronopus, Poir., Cranibe mariti))ia, 

 L., Hieracium umbellatuni, L., Stachys arvensls, L., and Sclcro- 

 chloa loliacea, Watson. 



Mr. John Renwick reported on an Excursion made to Rossdhu, 

 Luss, on 9th inst. Mr. Richard M'Kay stated that the most 

 interesting plants seen were Nyinphcea alba, L., Lobelia Dort- 

 manna, L., Lysimacliia vulgaris, L., Siuci Sparganiiim minimum, 

 Fr., the two last-named species being plentiful.

 tion recently opened for a few weeks in that town. Among the 

 plants observed were Cardaniine amara, L., Helianthemum 

 vulgare, Gcertn., Vicia sylvatica, L., Agrimonia Eupatoria, L.,

Mr. C. O. Sonntag read a paper on " Desmids and allied forms," 

 in which an interesting account was given of the morphology 

 and life-history of these plants, and the best method of collecting 

 them. A large number of illustrative specimens were afterwards 

 exhil)ited under the microscope.
