OPODELDOC—is an article of external use in STRAINS, BRUISES, and other complaints, as well with the human species as with the brute creation. It is prepared by dissolving three ounces of SPANISH SOAP, and one ounce of CAMPHIRE, in a pint of SPIRIT of ROSEMARY. Others dissolve the soap and camphire in rectified spirits of wine, adding OIL of ORIGANUM, and other essential oils. Its excellent properties are universally admitted in its various applications to the human frame; but doubts naturally arise how far it may contribute any great portion of EFFICACY to HORSES, or to any other animal, where the soap again coagulates, and constitutes so matted a mass upon the surface, that it is only with persevering difficulty the hair can be disunited even at the _second_ application. ORIGANUM, OIL OF,—is a well-known essential oil, extracted from the plant whose name it bears: it is an admirable collateral corroborant, when incorporated with judicious proportions of such other medicines as are proper for STRAINS, or a _relaxed_ state of the TENDONS. If used in too great quantities, or added to heterogeneous articles, it disunites itself almost immediately; and, instead of executing the office of a gentle STIMULANT, penetrating the pores, assumes the power of the milder class of CAUSTICS, occasioning an eschar upon the part impregnated, terminating with a loss of hair. OROONOKO—was one of the most celebrated horses of his time: he was bred by the late LORD PORTMORE; was got by _Crab_ out of _Miss Slamerkin_; foaled in 1743; and was own brother to _Othello_, the famous _Black and all Black_. OTHELLO—was the first name of that justly celebrated HORSE, so firmly fixed in the memory of every old SPORTSMAN of the present generation, by the more distinguished appellation of _Black and all Black_. He was bred by the late LORD PORTMORE; was got by _Crab_ out of _Miss Slamerkin_, who was got by _True Blue_. He was foaled in 1745, and was esteemed the first racer of his time, producing afterwards, as a STALLION, some very famous runners.
