20 QUATERCENTENARY STUDIES IN PATHOLOGY 



of the oesophagus. Of these 23 cases, 14 showed a malformation of the 

 heart ; of the 14, 10 showed lesions of the bulbis cordis ; in some cases 

 it was the pulmonary part of the bulbus which was non-developed, in 

 others it was the aortic. The important point is that these lesions were 

 similar to those I have just described in older hearts. It appears from 

 this evidence, then, that the malformations of the bulbus are the result 

 of the same agent as produces the condition of anencephaly, etc., with 

 which lesions malformation of the bulbus is so often associated.
