In offering for consideration a few ideas on the diseases of the pulp, I do not mean to infer that its pathology is different from that of any other part of the body. As a general rule, inflammation presents the same set of phenomena wherever it is situated, subject to the variations peculiar to the organ in its especial location. We must never forget that disease of an organ is seldom or never a local affair; in other words, its effects are farreaching and other structures must always become involved. In teaching the subject, this point is one that is very difficult to impress on a student's mind, for collateral anatomy, physiology and pathology seem to be forgotten in studies in the special structure under consideration. A simple carious cavity is not the only thing by which to diagnosticate a patient's suffering.
