The virulent, dreadful ulcer, that is so fatal in the human subject, and is called cancer, is unknown in dogs; yet there is very commonly a large scirrhous swelling of the teats in bitches, and of the testicles (though less frequent) in dogs, that as it sometimes becomes ulcerated, so it may be characterised by this name. In the early state of this disease, discutients prove useful; as vinegar with salt, and camphor and Spanish flies with mercurial ointment, have sometimes succeeded, taking care to avoid irritating the part so much as to cause blister. But when the swelling is detached from the belly, and hangs pendulous in the skin, it had better be removed; and, as a future preventative, suffer the bitch to breed. Scirrhous testicles are likewise sometimes met with; for these no treatment yet discovered succeeds, but the removal of the part, and that before the spermatic chord becomes much affected, or it will be useless.—_White._ CANCEROUS, _a._ Having the virulence of a cancer. CANDLE, _s._ A light made of wax or tallow, surrounding a wick of flax or cotton. Candles, as well as lamps, often afford good prognostics of weather. When the flames of candles flare and snap, or burn with an unsteady or dim light, rain, and frequently wind also, are found to follow. The excrescences from the wicks called funguses also denote rain and wind.—_Foster._ CANE, _s._ A kind of strong reed; the plant which yields the sugar; a lance. Canes are sometimes used for fishing-rods. CANELLA-ALBA, _s._ An aromatic stimulant. CANINE, _a._ Having the properties of a dog. CANKER, _s._ A worm that preys upon, and destroys fruits; a fly that preys upon fruits; any thing that corrupts or consumes; an eating or corroding humour; corrosion, virulence; a disease in trees. _Canker in the ear._—A common and troublesome disease, to which dogs are liable. To cure it, boil two ounces of best shag tobacco in a quart of water, until one pint is consumed; dip the dog’s ears, as it is boiling hot, into the tobacco water, until two inches above the cankered part; repeat it three successive days. To bring the hair again, burn some old shoe, and mix with a quarter of a pound of hog’s-lard, and frequently anoint the ears; but the readiest and best way to rid dogs of cankers, is to apply the rounding-iron. * * * * *
