from left to right. The inner surface of the tubular portion, with 

 the exception of its right wall, a concavity, and the continuation of 

 its external muscular coat on to the globe are covered with fine rugae, 

 and the walls are thick, whilst the remainder of the inner surface is 

 thin and smooth. The form of the stomach thus confers great ex- 

 tension on the lesser curvature.

The small intestine measures 8 feet in length, while the large in- 

 testine is 3 feet 4 inches long. The caecum, which is 1" 7'" in length, 

 is a simple dilatation to the right of where the small enters the large 

 intestine. It is somewhat pointed externally, and, immediately out- 

 side the small intestine, measures 2 inches in diameter, having a greater 

 capacity than the commencement of the large intestine.

The spleen measures 1" 5'" in length, 9'" in its greatest breadth, 

 and 4'" in thickness from before backwards. Its right margin is quite 

 straight and flat, whilst its external border curves outwards and down- 

 wards as far as the lower two thirds, where it rather abruptly arches 

 inwards and downwards. Its upper extremity is slightly bifid. 



The total length of the pancreas, when the gland is laid out, mea- 

 sures 3" 10'", the plane portion forming 2" 8'", and the head 1" 2'". 

 The head, for about one inch, is firmly attached to the duodenum,
