num to the liver, in an embryo of 50 mm. It may facilitate 

 an understanding of the subsequent figures (in determining 

 the position of the stomach, which in them has been re- 

 moved), especially if a comparison be made between them 

 and this one. 



The fundus of the stomach lies in the concavity of the 

 left lateral lobe, the pylorus rests upon the Spigelian lobe, 

 and the duodenum dee]Dly grooves the right central, the right 

 lateral, and the caudate lobes. A groove is also seen on the 

 right central and right lateral lobes which was occupied by 

 a piece of the small intestine.

The various lobes can be easily identified. In the me- 

 dian line, close to the junction of the left lateral and right 

 central lobes, two grooves are seen. The one on the left of
