NARROW HEELS.—Enlarged upon under "HEELS NARROW," which SEE. NAVEL-GALL—is an injury sustained upon the centrical part of the back-bone, corresponding with that part below, from whence it originally derived its present denomination. It is always occasioned by the _pad_ of the SADDLE being in itself too wide, (and deficient in stuffing,) letting the _iron_-work of the _tree_ come into contact with the SPINE; or from the long and constant use of a roller in the stable, till having lost the elasticity of its stuffing, it then becomes sufficiently _hard_, particularly with too tight buckling, to occasion the injury, which is often productive of much trouble, long vexation, and tedious disappointment. It is a disgrace to the rational part of the world, that cases should occur from neglect, indolence, or inattention, which may, with no more than just and necessary caution, be so easily prevented. A navel-gall, in the first instance, if immediately attended to upon the earliest discovery, (if that be so soon as the injury is sustained, or in its recent state of inflammation,) will mostly submit to mild astringent repellents, repeated at short intervals; and the contents of the inflammatory tumefaction will be absorbed into the circulation. But "as it is the curse of fools to be secure," so an impatient _repetition_ of the _cause_ occasions a constantly increasing addition to the injury, till the renewed HEAT and FRICTION upon the part constitute an eschar, or leather-like substance, upon the surface, which being separated, or coming spontaneously away, displays a _foul_, if not an INVETERATE ulcer, and requires no small share of Veterinary skill to insure a successful termination. NEAR-SIDE.—The near-side of a horse is the LEFT SIDE, and of course the side on which the rider goes to mount. The right-side of the horse is always called the OFF-SIDE; but the _right_ side, or the _left_ side, is never so termed, when speaking of a horse. It is the invariable custom to say, that horse is lame of the "_near_-leg before;" the other, is evidently defective in the "_off_-leg behind." NECK.—The neck of a horse has been so often enlarged upon under a variety of different heads, that little or nothing is left useful, entertaining, or instructive, to introduce upon the subject. All that can be required, will be found largely explained by referring to "HORSE" and "FOREHAND," where, if it is not already remarked sufficiently, it may be here more forcibly inculcated; that a horse with a short neck, is in general lower before than behind; that he is never easy in action; carries his head low, and lifts his legs with difficulty; is much addicted to tripping, or rather _blundering_, and with that pleasing perfection (so gratifying to the sensations of his rider) is always in danger of FALLING; in addition to which, it may be observed, that a horse of this formation is neither fleet or handsome.
