somewhat straggling habit, not from growing in wooded ground, but 

 probably from being the inhabitant of the less genial climate to 

 which the species is extended. It appears not to differ from Lathy rus 

 venosus of American botanists. Hab. Sands on the shore at Barra 

 Firth, Unst, Shetland, where Dr. Edmonstone had observed it for 

 several years. 



Ervum tetraspermum and Allium arenarium. — Hab. Near Kirkcud-

Mr. Campbell read a communication from Col. P. J. Brown of 

 Eichenbiihl nearThun, containing a sketch of the botany of the neigh- 

 bourhood of the lake of Thun, Switzerland, chiefly in reference to 

 the geographical distribution and altitude of the species enumerated. 

 The lake of Thun having an elevation of about 1900 feet above the 

 sea, and the surrounding country being much intersected by hills or 

 long ridges, the vegetation assumes a subalpine character on the pas- 

 tures about 1800 feet above the lake, comprising Trollius europceus, 

 Hieracium aureum, Tussilago alpina, &c. The following is given as an 

 approximation to the species usually met with at different altitudes 

 on the surrounding mountains. Between 2000 and 3000 feet, Arena- 

 ria verna and ciliata, Dry as octopetala, Cotoneaster vulgaris, Hieracium 

 villosum, &c. Between 3000 and 4000 feet, Silene acaulis, Cerastium 

 alpinum,Phaca astragalina, Oarytropis uralensis,Saxifraga oppositifolia, 

 Hieracium aurantiacum, Arbutus alpina, Ajuga alpina, Orchis pollens, 

 Carcx atrata, &c. Above 4000 feet, Gnaphalium alpinum and Leon- 

 topodium, Petrocallis pyrenaica, Draba tomentosa and stellata, Andro- 

 sace bryoides, &c. Col. Brown concludes his paper by stating that 

 he hopes to be able to communicate fuller information as to the pre- 

 cise elevations of the different localities mentioned on some future 

 occasion.

April 21. — Professor Wilson in the Chair. 

 Dr. Royle read a communication from Colonel Sykes, respecting 

 the vegetable and other productions of the Deccan, having reference 

 to a similar communication at the beginning of the year, showing 

 their immense extent in the eastern continent and adjacent penin- 

 sula, which yet remained to be made subservient to the arts and ma- 

 nufactures of this country. The paper was accompanied by a great 

 variety of specimens and an extensive herbarium. These he divided 

 into the gummy, the astringent, the fibrous, the oil-producing, and 

 the saponaceous and dyeing, being classified according to their uses 

 in the arts. The caoutchouc, belonging to the first class, was be-
