The small circles in tlie tables of the teeth merely indicate the apex of the inverted cone in which the infundibulnm originally existed, and any good observer looking at the two mouths would decide that " Kremlin " was older than " ; It is, however, quite certain that both horses were of the same age, and both of them much older than the teeth indicated them to be. A method of judging the age of the horse up to thirty years, by noting the length of a groove in the upper corner incisors, is referred to by Mr, Sidney Galvayne in his pamphlet on horse dentition. The groove to which Mr. Galvayne attaches so much importance is really a groove in the fang of the upper corner Fig. 22.—(a) Groove at the side of the upper corner Incisor at ten years of incisors. It is not seen until the horse has reached the age ot ten years, by which time the alveolar cavity has become shallow, the tooth has grown in length in proportion to the wear, and a portion of the fang—with the lateral groove—is exposed. This appearance is shown in the above illustration (Fig. 22) from Mr. Galvayne's book. According to the author, eleven years elapse before the lateral groove extends to the bottom of the tooth, and the age is to be judged during that time by the extension of the groove year by year. As the incisor is worn the fang grows longer, and the walls of the alveolar cavity are absorbed. It is evident that the extension of the groove year by year V' 12.
