1 52 RUMINANTIA. 



The Sheep [Ovis Aries, Linn.]. 



A sheep has but one punctum lacrymale, which belongs to the under 

 eyelid ; it is not placed as in the human, but is a little way on the 

 inside : it is pretty large, and is continued on to the ductus ad nasum 

 without any sac. The trochlearis muscle is like the obliquus inferior ; 

 and tbe origins of both are nearer the bottom of the orbit. 



Of the Nylghau [Antilope picta, Pallas 1 ]. 



The great or first bag of the stomach is at the lower part divided 

 into two, having an anterior and posterior edge ; the second bag is the 

 ' honeycomb ; ' the third is the ' parson's book ; ' the fourth is the true 

 stomach ; the last part of which seems to have most of the digestive 

 power. The food [in the first ?] was almost unaltered, only soaked. The 

 great bag is attached to the diaphragm on the left of the oesophagus 

 with the upper end of the spleen. The little epiploon is attached to the 

 first bag [rumen] on the right of the oesophagus ; to the second or honey- 

 comb bag ; to the ' parson's book ; ' and to the last bag and beginning of 

 the duodenum at the upper part to the liver. This membrane is a kind 

 of mesentery to all those parts, uniting them in general to the parts 

 above, and each part of the stomach to one another, and the hollow 

 curve of the last bag to itself. The great epiploon on the anterior part 

 on the right, is attached to the duodenum ; from thence along the lower 

 edge of the last bag, as in the human, and then crosses the anterior 

 edge of the bag near the upper part to the left. Upon the left of that 

 bag it passes down along it to the division of the lower end towards 

 the apices [of the rumen] ; then gets between these two apices towards 

 the right again, forming posterior lamella?, and there is attached to the 

 root of the mesentery and transverse passage of the colon, and is united 

 to the right, to the anterior lamella?. The last bag [abomasus] is bent 

 upwards upon itself, somewhat similar to the last part of the stomach, 

 in the human and other animals, and terminates in the duodenum. 



The duodenum passes upwards towards the liver, and there becomes 

 rather firmly connected by means of the vessels of that viscus ; it then 

 passes down on the right side pretty low and loose, having a meso- 

 duodenum which becomes narrower downwards to the loins ; from 

 thence it passes obliquely upwards and towards the left, behind and to 

 the left of the mesentery, and becomes a loose intestine. The ileum 

 passes into the caecum somewhat on the right, and pretty low down ; 

 about a foot and a half from its blind end there is a mesenteiy which
