(Abstract.) 

 General Purpose. 



This paper embodies the results of an enquiry into the topographical 

 anatomy of the abdominal viscera in man. The work falls into two 

 main parts. First, that dealing with the relations of the viscera to 

 the surface of the body ; and, second, that dealing with the relations 

 of the viscera to one another. 



With regard to the first part : It is to be remarked that the 

 methods of mapping out the abdomen at present in general use are 

 open to certain objections ; for the reasons that the lines used to 

 divide the abdomen transversely are drawn at variable distances from 

 one another, the variation not being determined by the dimensions of 

 the body ; that the points between which the upper transverse abdominal 

 line is drawn are very variable in their level, so that in some cases the 

 transverse lines come very near together leaving a large part of the 

 abdomen above them not mapped out ; in other cases the lines may be 

 far apart ; and, moreover, the points between which the upper transverse 

 line is to be drawn are not always easily determined, and it happens
