Other remarkable remains of a degree of civilisation which no longer exists, are the granite vases with graceful labyrinthine ornaments, and the earthen masks resembling Roman ones, which have been discovered on the Mosquito coast, among wild Indians. (Archæologia Britan. vol. v. 1779, p. 318-324; and vol. vi. 1782, p. 107.) I have had them engraved in the “Picturesque Atlas” which accompanies the historical portion of my Travels to the Equinoctial Regions. Antiquaries are astonished at the similarity of these ornaments (resembling a well-known Grecian form), to those of the Palace of Mitla, near Oaxaca, in Mexico. In looking at Peruvian carvings, I have never remarked any figures of the large-nosed race of men, so frequently represented in the bas-reliefs of Palenque in Guatimala, and in the Aztec paintings. Klaproth remembered having seen individuals with similar large noses among the Chalcas, a northern Mogul tribe. It is well known that many tribes of the North American red or copper-coloured Indians have fine aquiline noses; and that this is an essential physiognomic distinction between them and the present inhabitants of Mexico, New Granada, Quito, and Peru. Are the large-eyed, comparatively fair-complexioned people, spoken of by Marchand as having been seen in 54° and 58° lat. on the north-west coast of America, descended from an Alano-Gothic race, the Usüni of the interior of Asia?

We obtained specimens of the climbing plant, from the juice of which the curare is prepared, at Esmeralda on the Upper Orinoco, but unfortunately we did not find it in blossom. Judging by its physiognomy it appears to be related to Strychnos (Rel. hist. T. ii. p. 547-556). Since the notice in the work referred to of the curare or ourari (previously mentioned by Raleigh, both as a plant and as a poison), the brothers Robert and Richard Schomburgk have done much towards making us accurately acquainted with the nature and preparation of this substance, of which I was the first to bring a considerable quantity to Europe. Richard Schomburgk found the plant in blossom in Guiana on the banks of the Pomeroon and the Sururu in the territory of the Caribs, who are not, however, acquainted with the manner of preparing the poison. His instructive work (Reisen in Britisch-Guiana, Th. i. S. 441-461), contains the chemical analysis of the juice of the Strychnos toxifera, which, notwithstanding its name and its organic structure, does not contain, according to Boussingault, any trace of strychnine. Virchou and Münter’s interesting physiological experiments make it probable that the curare or ourari poison does not kill by mere external absorption, but only when absorbed by living animal substance of which the continuity has been severed (_i. e._ which has been wounded
