The other patient, who was forty-five years old, presented an advanced case of myelitis, and caries of the vertebræ, when there formed, at the lower part of the sternum, a hard and indolent tumor, which soon became apparently a scrofulous ulcer. The pus from this ulcer was ichorous, and the edges were of a violet red, swelled and hard; and the soft parts adhered to the subjacent bones. The lymphatic ganglions of the neck swelled for some time, but they then returned to their natural state. M. Dalandeterie adds, that these two cases have been selected from many other similar or analogous facts: hence, he considers caries of the vertebræ as having then been the consequence of a scrofulous principle, which was developed by onanism. If, however, we carefully analyze these facts, we shall find that they do not indicate a scrofulous disease, the development of which was but slightly favored by the age of the patients, as a _tubercular_ affection--that is, a disease which might be developed at every period of life. We think that tubercles were developed, in the phalanges, in the first case; and in the sternum, in the second; that these tubercles softened, and suppurated; and thus were formed the apparent scrofulous ulcers presented by these individuals. Probably, a similar circumstance occurs in the vertebræ, the bodies of which are destroyed; for distinguished observers, especially Delpech, have regarded Pott’s disease as a tubercular affection of the body of these bones. The cases of Dalandeterie would prove only that onanism favors the development of tubercles. Unfortunately, they are not the only cases, as we shall see, which establish this fact.
