QUATERCENTENARY STUDIES IN PATHOLOGY 



Any descriptive account of the anatomy of the heart, even by those 

 who write clearly and well, is particularly hard to follow, hence it is 

 necessary for me to use every aid to make my description intelligible. 

 This end will be served if, at the outset, I indicate by the use of a figure, 

 the part of the normal human heart which, on the evidence to be 

 produced, I believe to be formed from the bulbus cordis. That part is 

 the infundibulum of the right ventricle (see Fig. 2). The wall of the right 

 ventricle, when opened in the manner shown in figure 2, is seen to show 



Figure 2, normal human heart with the right ventricle opened, 

 (i) Pulmonary artery. 

 (2) Aorta. 



Pulmonary valves (upper limit of infundibulum). 



(5) Thickenings in wall of right ventricle at the junction of the infundibulum 



and body of the right ventricle. 

 Body of the right ventricle.

A, right septal band, B, left septal band of infundibulum. The line between A and B 

 indicates the position of the septal raphe of the infundibulum.
