This is one of the ductless glands situated behind the sternum. In normal people it is extinct by the time of puberty. 'The only thing that makes this gland of interest is that sometimes it remains and takes on hypertrophy, producing a tumor in the mediastinum. I have met with but one case. The disease started to develop in the young man at about sixteen to seventeen years of age. It grew so, rapidly that it displaced the heart several inches downward and to the left. The patient suffered a great deal, and died at the end of two, years after the tumor had started to grow.

Treatment

No treatment seemed to be of any avail; in fact, as in the case of many other tumors situated in the vital parts of the body, nothing can be done after they have once started. The time to cure such derangements is before they have started to grow. I knew this boy when he was an infant at the breast. He was as healthy and normal as other boys, and would have remained so if he had been properly taken care of and his eating had been of the right sort.
