incisors together or in apposition: the consequence is, that the lower incisors being active instruments, have to perform their functions at considerable disadvantage; but, nevertheless, they act and receive wear. The upper incisors, however, are, in such mouths, subjected to little attrition; the corner, and a portion of the lateral nippers alone, meeting each other; hence the central nippers, which grow more forward than they ought, at length project downwards, and overhang those of the lower jaw. This arrangement of the incisors constitutes what is called a "parrot mouth," because of the resemblance which the teeth bear to the bill of the bird. Most old horses are more or less parrot-mouthed; but young horses also occasionally exhibit mouths of this description, and in these last it is certainly a defect, for in a state of nature, or at grass, the animal would be necessitated to tear rather than bite its food. The proprietor of such a beast, therefore, can or ought never to turn the creature out, but keep it constantly in the stable, and under many circumstances this would entail inconvenience and expense. There is nothing to be done for such a malformation, but an allowance should be made for it in the price. That the reader may be able to recognise it, a copy of a mouth, in which the deformity was well marked, is here presented. The animal, which was introduced to my notice by my talented friend, Mr. Broad, of Paddington, was twenty-one years of age; and though more conspicuous cases of the kind are sometimes seen, the one I have chosen for illustration shows a rather greater malformation than is usually met with; but, nevertheless, it well illustrates the point upon which I have been dwelling.
