For a number of years I have been studying the abnormalities of the circulatory system resulting from developmental disturbances. One paper relating to the aortic arches has already appeared, Poynter (1916), and in this one I shall confine myself to the anomalies of the heart. There are few subjects which have attracted more attention among the medical profession than the irregularities in the developmen~ of the heart and great vessels, but in the case of the heart the interest is not so much from the teratological side as in the case of the arteries; its developmental defects are frequently of such serious consequence to the life of the individual as to command the attention of the clinician and pathologist, with the result, that these cases have been studied as a pathological problem rather than an embryological one. I had first intended to report the cases I have had the opportunity of studying, but as my bibliography has grown there has seemed to be no profit in adding more examples to those already reported, since I have observed no new conditions or complexes. In the earlier study it was frequently difficult to find the literature relating to any specific lesion, consequently I have included a full literature list so that the cases which 'appear as a basis for this study may be readily available to anyone desiring to consult them.
