LINNEAN SOCIETY OF LONDON.

January 17, 1889. Mr. W. Carruthers, F.R.S., President, in the chair. The following were elected Fellows: J. R. Green, M.A., Prof. Botany, Pharmaceutical Society; R. J. Harvey Gibson, M.A., Lecturer Botany, Univ. Coll., Liverpool; James W. White, of Clifton, Bristol; and Herbert Stone, of Handsworth, Birmingham. -On behalf of M. Buysman, of Middleburg, Mr. B. D. Jackson exhibited a series of careful dissections of Nymphæa cærulea collected by Dr. Schweinfurth in Egypt.-Mr. D. Morris exhibited specimens of drift fruit from Jamaica, where he had collected no less than thirty-five different kinds brought by the Gulf Stream from the mouths of the Orinoco and Amazon. Although the species exhibited had not been determined with certainty, it was believed to be probably Humiria balsamifera (the flower of which is figured by Eichler, Flora Brasiliensis,' vol. xii. pt. 2, 430, pl. xcii. fig. 1), but the fruit undescribed. It was commonly known in French Guiana as Bois rouge, and from it was obtained a gum used medicinally and burnt as incense. Mr. T. Christy exhibited a material felted from Manilla hemp, and waterproofed, very strong and light, and particularly useful for surgical bandages, for which purpose it was highly recommended by army surgeons. Mr. F. Crisp exhibited some specimens of agate so curiously marked as to lead to the erroneous supposition that they enclosed fossil insects and crustacea.-A paper was then read by Mr. J. G. Tepper, “On the Natural History of the Kangaroo Island Grass Tree, Xanthorrhea Tateana." This tree grows abundantly in Kangaroo Island, South Australia, in poor, gravelly and sandy soil, intermixed with ferruginous concretions, and attains a height of from six to fourteen feet, with a diameter of six to eighteen inches, and a floral spike of from ten to nineteen feet. It is thus a most conspicuous plant, and lends a peculiarly weird aspect to the country it occupies. Its rate of growth is described as very slow, old settlers having remarked but little change in individual trees after thirty years' observation. The most remarkable feature in the structure of the stem is the formation of a dense ligneous central core immediately above and connected with the roots, exhibiting numerous annular zones, traversed by transverse (medullary) fibres. The flowers are borne in a dense spike upon a smooth peduncle. Individually they are inconspicuous, of a whitish colour, and develop a strong odour and abundant nectar during the warmer part of the day, when they are visited and fertilised by hymenopterous insects, the most remarkable being a large metallicgreen Carpenter Bee (Xylocapa), which tunnels out cells in the dead flower-stalks.
