96 CARNIVORA. 



What answer to the round ligaments are here pretty broad, crossing 

 the broad ligament. The ovaria are enclosed in a capsule which has a 

 very small opening into it. The fimbriae are on the inside of these 

 bags, but close to the opening 1 . 



The bags at the anus are very small ; and the openings are nearly .as 

 large as the bags themselves ; by which means they are easily to be 

 inverted so as to look like piles externally. 



Captain Cartwright says that white bears do not sleep in the winter ; 

 they come further south as the white foxes do. He has, at Labrador, 

 seen the tracts of their feet in the summer : he was told by the Indians 

 that they go into caves to avoid the heat in summer. A gentleman shot 

 one swimming, and when he had skinned it, the four quarters weighed 

 70 score pounds. He had not weights to weigh it at once, but by pieces, 

 201bs. a piece (1400 lbs.).

Of a Seal [Phoca vitulina, Linn., and Phoca grcenlandica, Linn. 2 ] . 



The tongue is pretty broad at the base, becoming rapidly narrower 

 towards the apex, where it is bifid 3 . There is no uvula. The os 

 hyoides is attached to the head by a ligament. There is the muscle 

 passing between the tongue and epiglottis. The edges of the epiglottis 

 are attached to the tips of the arytenoid cartilage by the rimula laryngis. 

 There are no sacculi laryngis. The two thyroid glands, one on each 

 side of the cricoid cartilage, lying upon the n jck, are of an oval figure. 



The lungs are rather long and small : [on] the right side they appear 

 as if they were made of two lobes united by a loose cellular membrane : 

 on the left side of three lobes united in the same way : they are of a 

 florid red : the cells do not seem to be larger than in the human. The 

 thymus is very small. 



The pericardium is very thin, adhering to the diaphragm by a broad 

 surface ; but this adhesion is by a ductile cellular membrane, so that it 

 is moveable upon the diaphragm in some measure ; yet the inferior vena 

 cava is pretty long, for the apex of the heart is turned down so that the 

 basis is a good way from the diaphragm, and the pericardium adheres 

 posteriorly to the vena cava ; and, between it and the oesophagus, there 

 is a thin membrane.
