✦ Synopsis

Anatomical literature contains numerous descriptions of the more striking aortic anomalies. I n most instances, these have been reports upon individual cases, and have not presented the lesser variations which are regularly encountered in every dissection laboratory. It is the object of the present article to supply information on the simpler varieties as well as upon the infrequent, but arresting, types.

Methods

Records were prepared from an examination of 216 adult specimens, consecutively studied ;2 each case was sketched and measured. The classification followed is the one predominani in the literature ; devised by Adachi ( '28) it was later amplified by Williams and associates ( '35). I n the current tabulations (tables 1 and 2 ) this modified classification has been employed, the alphabetical letter being placed at the head of the appropriate column. I n order to facilitate comparison with the excellent records presented by DeGaris ( '23, '33), the latter's Contribution no. 286 from the Anatomical Laboratory of Northwestern University Medical School.

The writers have been permitted to examine the specimens in the gross anatomical laboratories of The University
