134 TRANSACTIONS, NATURAL HISTORY SOCIETY OF GLASGOW. 
24th Novemper, 1896. 
Mr. Robert Kidston, F.R.S.E., F.G.8., President, in the chair. 
The Chairman referred to the great loss the Society had 
sustained through the death of Mr. David Robertson, LL.D., 
F.L,S., F.G.8., who had been an active member since 1852, and 
had, during that long period, contributed many valuable papers 
and important exhibits. The Hon. Secretary was instructed to 
convey an expression of sympathy to Dr. Robertson’s family, 
Mr. A. Somerville, B.Sc., F.L.S., the Society’s delegate at the 
opening of the Gatty Marine Laboratory, St. Andrews, submitted 
his report, which was read by the Rev. G. A. Frank Knight, 
M.A. 
Mr. C. O, Sonntag, Edinburgh, was elected as a Corresponding 
Member of the Society. Messrs. William Bowie, 188 Comely- 
park Street; W. A. Donnelly, Miltonhill, Milton of Colquhoun, 
Bowling ; Chas. Kirk, 156 Sauchiehall Street; John R. Lee, 42 
Dundas Street; James Murray, 3 Campsie View, Hamilton ; 
John Robertson, Eastwood, Thornliebank ; and John Sloane, 201 
Dumbarton Road, were elected as Ordinary Members. 
Mr. Geo. Russell, for Mr. J. B. Mirrlees, exhibited a number

bears a spur from a foot to eighteen inches in length. This plant 
is referred to by Darwin in his work on the fertilisation of 
orchids. In connection with this exhibit Mr. G. F. Scott Elliot, 
M.A., B.Sc., F.LS., F.R.G.S., communicated some notes. He 
stated that it was not uncommon near Fort Dauphin, in the South- 
east of Madagascar. He had been obliged to remain there on one 
occasion for three months, and during that time made some 
attempts to find its fertiliser. He caught many varieties of 
Sphinx Moth on it, some of them having proboscidea fully 
eighteen inches long, but he was never able to catch one on the 
flowers. These moths went eventually to Paris, and M. A. 
Grandidier declared them to be all new forms. <Angrecum 
superbum, Thow., was also common at Fort Dauphin, and with 
this orchid Mr, Scott Elliot had been more fortunate, as he saw a 
beautiful little Sun-bird (Cinnyris souimanga (Gm.) ) sipping its 
honey. ‘The flowers of this Angreecum grow pretty densely along 
the peduncle, and it was very interesting to watch the neat and-
