Mel-Honey.-A saccharine secretion deposited in the honeycomb, by Apis mellifica, the Hive Bee.

Characters and test.-When recently separated from the honeycomb, it is a viscid translucent liquid, of a brownish yellow colour, which gradually becomes partially crystalline and opaque. Has a peculiar heavy odour, and very sweet taste.

Impurity. -Starch.

Composition.-Honey is a complex mixture of several kinds of sugar (cane and grape sugar, levulose or inverted sugar, derived by fermentation from the cane sugar); wax, pollen, colouring and odorous matters, etc.

Honey is also contained in Mel Boracis, Oxymel Scillae, Con-fectio Piperis, Confectio Scammonii, and Confectio Tere-binthinae.

Action And Uses

Honey increases the secretions of the mouth and throat, and thus acts as an emollient, relieving dryness, pain, cough and dysphagia. It is a popular ingredient of gargles, linctuses and cough mixtures, but to be useful must be properly employed as the oxymel, or in combination with lemon, which has a similar action on the mouth and pharynx. As a vehicle for borax it is used in aphthae of the mouth, but is inferior to glycerine because fermentable. Honey is also laxative and nutritive.

Cera Alba-White Wax.-Yellow wax bleached by exposure to moisture, air, and light.

Characters.-Hard, nearly white, translucent. Not unctuous to the touch; does not melt under 150°.

Cera Flava-Yellow Wax.-The prepared honeycomb of the Hive Bee, Apis mellifica.

Characters.-Firm, breaking with a granular fracture, yellowish, having an agreeable honey-like odour. Not unctuous to the touch; does not melt under 140°; yields nothing to cold rectified spirit, but is entirely soluble in oil of turpentine.

Impurity.-Starch.

Composition. - Wax differs from ordinary fats in containing, as its base, not glycerine, but another alcohol, melisyl-alcohol, in union with palmitic acid, C30H61O.C16H31O2.
