dated Norway House (a station of the Hudson's Bay Company), July 20th. 

 They were then in good spirits, and busy making preparations for departure. 

 They left this post a few days afterwards, and had descended a considerable 

 distance down the Columbia river, when on the 22d of October, in the 

 evening, " while running one of the rapids below Dalles des Morts, the boat 

 unfortunately filled," and the two botanists, including ten other persons, one 

 of whom was Mrs. Wallace, were lost. 



The tract over which the travellers passed having been previously fully 

 explored, it was not to be expected that they could collect any thing worth 

 sending home. Mr. Paxton concludes with the following paragraph : — 



" When time has in some measure allayed the sorrow and disappointment 

 occasioned by this grievous catastrophe, and the affairs connected with the 

 expedition have been fully investigated and adjusted, it will remain for 

 decision whether another attempt to prosecute the design to which these 

 young men have so haplessly fallen victims shall be hereafter ventured on."

AUGUST 21. 1838. — Ordinary Meeting. The following objects were ex- 

 hibited : from Messrs. Mountjoy, nurserymen, Ealing, Passiflora nigelliflora, 

 a species nearly related to the well known P. fce'tida. The flowers were sur- 

 rounded by a curious glandular fringed involucre, which, it was stated, pro- 

 duces some curious phenomena of motion, and presents a beautiful appearance 

 if viewed in water under a microscope. The oily matter contained in the 

 glands is apparently expelled with some force into the water, where it causes 

 eddies and a disturbance of a remarkable kind. From Messrs. Rollisson and 

 Sons, nurserymen, Tooting, a magnificent specimen of the beautiful new Japan 

 lily, called Z/ilium speciosum, together with Maxillaria vitellina, a rare Bra- 

 zilian epiphyte, and Renanthera coccinea, in great perfection. Of the latter, it 

 was stated that the probable cause of its so seldom flowering in collections 

 might perhaps be found in the dissimilarity between its treatment in gardens 

 and its natural habits. It is a common plant at Macao, where it is planted in 

 pots of the hard mud of the country, and runs over old walls, producing its 

 gaudy panicles of scarlet flowers in abundance annually. During the warm 

 season it pushes forth vigorous branches, and clings by its long twisted roots 

 to any substance it may be placed near ; but, during winter, it is exposed to a 

 temperature of 40° Fahr. ; and in the spring it is parched by cold north winds, 

 which are so dry as to split timber, and to produce much inconvenience to the 

 human constitution. From Mr. John Breese, gardener to Sir Thomas Neave, 

 Bart., of Dagnam Park, a noble bunch of the Cannon Hall muscat grape. It 

 was very like the figure published in the Transactions of the Society, vol. i. n. s. 

 p. 169. fig. 5., but was larger in all respects ; and it fully established the claim 

 of this valuable variety, to be placed on a level, in point of excellence, with the 

 muscat of Alexandria. In the opinion of Mr. Breese, it even excels that va- 

 riety, as it is earlier, and has but one stone in a berry. From the Society's 

 garden, a collection of flowers, among which were Fuchsia cylindrica, a pretty 

 new dioecious species, with scarlet flowers, from Mexico; and Ledocarpon 

 pedunculare, a little-known half-hardy Chilian shrub, with clusters of large 

 brilliant yellow flowers.
