The purpose of this paper is to emphasize again three distinct facts with reference to enlargement of the thymus: (1) The condition is much commoner than is ordinarily supposed. (2) The diagnosis can be made definitely by means of simple physical examination and the Roentgen ray. (3) In the Roentgen ray we possess a therapeutic agent, which, in and of itself, will effect a cure in the vast majority of cases.
1. Occurrence.—According to some clinicians, enlargement of the thymus is supposed to be a rather rare condition. Those of us who have been particularly interested in the condition have been able to prove the fallacy of this view. The condition is in reality quite common. It is rather astonishing to note how frequently it is to be found if it be systematically searched for. As illustration of this I may refer to the paper of Dr. J. E.
