third : in short, it makes a great many turnings and windings which are 

 not at all regular, and in such manner as not to be easily described — 

 indeed not to be unravelled so as to be understood — these turnings and 

 windings lying all together and being closely connected to one another. 

 The rectum passes down seemingly pretty near the middle of the spine 

 into the pelvis 1 . 



The liver is small in proportion to the size of the animal, and is 

 properly made up of one lobe with a small fissure in it, and lies princi- 

 pally in the right side and middle of the body : it has a detached lobe 

 upon the right side, and has a swelling analogous to the lobulus Spigelii. 

 The gall-bladder lies in a sulcus in the right side of the liver. The 

 cystic duct runs along the same sulcus, and receives a number of small 

 ducts into it as it passes along, and joins the hepatic duct, which seems 

 to come chiefly from the left side ; and the ductus communis enters the 

 duodenum where we said it made its first turn obliquely. 



The pancreas lies just below the liver, having its larger part, as it 

 were, across the spine ; having, however, a process that runs down along 

 the duodenum, between it and some of the turns of the colon, in the 

 centre of which process passes the duct which enters the duodenum 

 about a foot from the entrance of the hepatic duct. 



The kidneys are conglomerate. The pelvis of the left had something 

 peculiar in its course, with its ureter ; it is corroded 2 . The right had 

 the common structure 3 . 



The contents of the thorax are like those of other quadrupeds. The 

 apex of the heart is turned rather forwards and a little upwards. 



The external parts of generation, and the anus, are just like those of 

 a cow : the internal parts, as they are seen in the pelvis, are, the uterus 

 with the two horns, which horns are a little convoluted at their ends, 

 the Fallopian tubes and ovaria. The tubes run in the broad ligament, 

 not upon the edge as in the human, but some way from the edge : they 

 are very much like the vasa deferentia, for they are not soft tubes as in 

 the human, but hard; and become softer and wider towards the 

 1 morsus diaboli,' which is continued from the opening of the tube to 

 the ovarium. 



The ovaria are placed on the posterior surface of a broad ligament, 

 some way from the tube ; they are small, hard, and rounded bodies. 

 All that part of the broad ligament on which the tube is placed, and 

 between it and the ovarium, is pretty broad and is pouched ; making a 

 kind of capsule for the ovarium, but which does not seem to cover it.
