Emil Wadstein1 has collected 113 cases of stenosis and obliteration of the aorta in the vicinity of the ductus Botalli; of these five are new cases. Ten of the total number are purely clinical cases, in which the diagnosis has not been confirmed by postmortem examination. In order to obtain a clear notion of the normal conditions, so as to be able to differentiate between a physiologic and pathologic narrowing of the place in question, the author also examined the aorta of 105 children, whose ages varied from newborn to three years.
With respect to the pathologic anatomy of this condition, then narrowing may occur in all possible degrees to atresia, which was present in twenty of the cases. The maximum degree of narrowing was found to be situated above the duct of Botalli in 16.4 per cent.; at the point of the duct in 38.8 per cent., and
