[_Lobelia. I._ 193. Longiflora. Grows in the West Indies, and spreads such deleterious exhalations around it, that an oppression of the breast is felt on approaching it at many feet distance when placed in the corner of a room or hot-house. Ingenhouz, Exper. on Air, p. 14.6. Jacquini hort. botanic. Vindeb. The exhalations from ripe fruit, or withering leaves, are proved much to injure the air in which they are confined; and, it is probable, all those vegetables which emit a strong scent may do this in a greater or less degree, from the Rose to the Lobelia; whence the unwholesomeness in living perpetually in such an atmosphere of perfume as some people wear about their hair, or carry in their handkerchiefs. Either Boerhaave or Dr. Mead have affirmed they were acquainted with a poisonous fluid whose vapour would presently destroy the person who sat near it. And it is well known, that the gas from fermenting liquors, or obtained from lime-stone, will destroy animals immersed in it, as well as the vapour of the Grotto del Cani near Naples.] [_So, where Palmira._ I. 197. Among the ruins of Palmira, which are dispersed not only over the plains but even in the deserts, there is one single colonade above 2600 yards long, the bases of the Corinthian columns of which exceed the height of a man: and yet this row is only a small part of the remains of that one edifice! Volney's Travels.] (As the bright orb of breezy midnight pours 200 Long threads of silver through her gaping towers, O'er mouldering tombs, and tottering columns gleams, And frosts her deserts with diffusive beams), Sad o'er the mighty wreck in silence bends, Lifts her wet eyes, her tremulous hands extends.-- 205 If from lone cliffs a bursting rill expands Its transient course, and sinks into the sands; O'er the moist rock the fell Hyæna prowls, The Leopard hisses, and the Panther growls; On quivering wing the famish'd Vulture screams, 210 Dips his dry beak, and sweeps the gushing streams; With foamy jaws, beneath, and sanguine tongue, Laps the lean Wolf, and pants, and runs along; Stern stalks the Lion, on the rustling brinks Hears the dread Snake, and trembles as he drinks; 215 Quick darts the scaly Monster o'er the plain, Fold after fold, his undulating train; And, bending o'er the lake his crested brow, Starts at the Crocodile, that gapes below.
