The horn of the Rhinoceros, single or double, has its special history by the way of popular tradition. From the earliest times this horn has been supposed to possess preservative virtues and mysterious properties--to be capable of curing diseases and discovering the presence of poison; and in all countries where the Rhinoceros exists, but especially in the East, such is still the opinion respecting it. In the details of the first voyage of the English to India, in 1591, we find Rhinoceros' horns monopolised by the native sovereigns on account of their reputed virtues in detecting the presence of poison. Thunberg observes, in his "Journey into Caffraria," that "the horns of the Rhinoceros were kept by some people, both in town and country, not only as rarities, but also as useful in diseases, and for the purpose of detecting poisons. As to the former of these intentions, the fine shavings were supposed to cure convulsions and spasms in children. With respect to the latter, it was generally believed that goblets made of these horns would discover a poisonous draught that was poured into them, by making the liquor ferment till it ran quite out of the goblet. Of these horns goblets are made, which are set in gold and silver and presented to kings, persons of distinction, and particular friends, or else sold at a high price, sometimes at the rate of fifty rix-dollars each." Thunberg adds:--"When I tried these horns, both wrought and unwrought, both old and young horns, with several sorts of poison, weak as well as strong, I observed not the least motion or effervescence; but when a solution of corrosive sublimate or other similar substance was poured into one of these horns, there arose only a few bubbles, produced by the air which had been enclosed in the pores of the horn and which were now disengaged." Rankin (in his "Wars and Sports") states this mode of using it: a small quantity of water is put into the concave part of the root, then hold it with the point downwards and stir the water with the point of an iron nail till it is discoloured, when the patient is to drink it. FOOTNOTE: [5] The conveyance of a Rhinoceros over sea is a labour of some risk. In 1814 a full-grown specimen on his voyage from Calcutta to this country became so furious that he was fastened down to the ship's deck, with part of a chain-cable round his neck; and even then he succeeded in destroying a portion of the vessel, till, a heavy storm coming on, the Rhinoceros was thrown overboard to prevent the serious consequence of his getting loose in the ship. STORIES OF MERMAIDS. Less than half a century ago, a pretended Mermaid was one of the sights of a London season; to see which credulous persons rushed to pay half-crowns and shillings with a readiness which seemed to rebuke the record--that the existence of a Mermaid is an exploded fallacy of two centuries since.
