REARING—is the most dangerous vice of all a restive horse retains in the catalogue of his untoward _qualifications_: it is generally termed REARING an END, and when carried to the extreme, is hazardous beyond description; as it is hardly possible for the best horseman existing to keep his seat, when a horse repeatedly assumes that unnatural position. Recent instances have occurred directly opposite in their consequences; one in which the RIDER was _killed_; in the other, the horse. In such an alarming and critical predicament, the most probable means of safety is, to gradually loosen the reins, and, by bearing the weight of the body close to the neck of the horse, endeavour to accelerate his preponderation. RECHASING—is a sporting term, but little known, and never used, except in the official language of a forest and its environs. Rechasing is the discovery and driving home of outlying deer, and other beasts, to the district from whence they had strayed. RECHEAT—is a recall of the hounds with the horn. REGULUS,—the name of a horse whose performances upon the _turf_, and celebrity as a STALLION, were never exceeded in this kingdom. He was bred by LORD CHEDWORTH, and foaled in 1739. He was got by the _Godolphin Arabian_; his dam by the _Bald Galloway_, grand-dam by _Snake_, out of _Old Wilkes_, a daughter of _Old Hautboy_. REGULUS won seven ROYAL plates in one year, and never was beat. He afterwards covered in the north, and was the sire of _Adolphus_, _Trajan_, the dam of _Eclipse_, the grand-dam of _Highflyer_, and many other capital horses and mares; through whose veins his blood has been transmitted in direct and oblique lines to every stud of eminence in the kingdom. Since which there have been three of the same name in succession. The first bred by MR. BASSET, foaled in 1750, got by _Regulus_, dam by _Whitefoot_, grand-dam by _Hip_. The second bred by MR. SALT, foaled in 1764, got by _Regulus_, dam by _Regulus_, (bred _in_ and _in_,) grand-dam by _Partner_. The last was foaled in 1788, got by _Young Morwick_, dam by _Turk_, grand-dam by _Young Cade_. REINS—are the parts of a bridle which are affixed to the eyes of the bit, or bits, on each side a horse's mouth, pass up the horse's neck, and are united at the reverse end, where the junction of both are held in the hand of the rider. A snaffle-bridle, and a hard-and-sharp, have each of them two reins; a Pelham and a Weymouth have each four. REINS.—The reins of a horse are the parts where the kidnies are seated; and the word is generally used in a synonymous sense with _loins_. When a disorder arises, or a defect is observed, in these parts, it may be supposed to have originated in some short and sudden turn in a narrow stall; carrying too heavy a weight, or drawing too large a load. Whenever such injury is sustained, a difficulty of staling, partial dribblings, or the urine very high-coloured, and tinged with blood, will soon point out the seat of the complaint.
