I shall make no apologies for presenting to the Society the report of a case and a brief paper upon so rare a condition as insufficiency of the pulmonary valves and the rarer condition of relative insufficiency. If we would make accurate anatomic diagnoses of the commoner valvular affections, we must have some familiarity with the signs of the rare ones. I am confident that you will all agree that we should not content ourselves with the diagnosis, "heart disease," but should endeavor in all cases to make as detailed a diagnosis as possible.
Relative insufficiencies, that is, those due to enlargement of the orifices rather than to contraction of the cardiac valves, are now admitted by almost all clinicians. Those upon the two auriculo-ventricular orifices and the aortic orifices are well known and the recorded cases are very numerous.
The relative insufficiency of the pulmonary valves has received very
