The vet-erinary practitioner knows that the teeth are worthyof attention, and he feels that their indications, scien-tifically interpreted, will seldom mislead. Surgeon J. H. Walsh, in his excellent work, TheHorse; in the Stable and in the Field/ says: In order to be able to estimate the age of the horseby his teeth, it is necessary to ascertain, as nearly asmay be, the exact time at which he puts up his milkteeth, and also the periods at which they were replacedby the permanent. Finally it becomes the provinceof the veterinarian to lay down rules for ascertainingthe age from the degree of attrition which the perma-nent teeth have undergone. For these several purposesthe horses mouth must be studied from the earliestperiod of his life up to old age. Judging the age by the teeth is even more compli-cated and difficult than is shown by the foregoing ex-tracts. Among other complications worthy of consid-eration are the following:. titfja creed-moor marks, hard to sit. 209 About the ninth year a mark, which is sometimesmistaken for the infundibulum, appears on the centralincisors. Girard named it the dentinal*star, but it is also called the fang-holeand secondary mark. Dentinal star isperhaps the most proper name, for themark is due to the presence of second-ary dentine, into which the remains ofthe pulp has been converted. The con-version of the pulp into dentine preventsthe cavity from becoming a reservoir for food, forotherwise it would become such as soon as reached bywear; and it preserves the tooth from decay, afford-ing a good illustration of Nature barricading pulp cavity is lined with dentine; the dentineinto whic
