Anatomical Rudiments 



sow are arranged in two parallel lines, extending 

 from the abdominal to the sternal region. Gesta- 

 tion is multiparous. The pig is omnivorous, 

 and as an aid tu digestion a liberal supply of coal 

 should be allowed, apparently proving beneficial. 



The Dog and the Cat 



The skeletons of both are particularly adapted 

 for rapid progression and the muscular system is 

 well developed ; the olfactory bulbs, or organs 

 of smell, are large and the sense of smell keen. 

 The brain attains only a moderate degree of 

 development, much less than that of the monkey 

 or parrot. The molar teeth are specially adapted 

 for flesh-tearing and 4 tushes are present. The 

 muscles of mastication are large and there is a 

 deep pit to lodge the muscles of the lower jaw. 

 The orbital arch is incomplete above in both animals 

 — a short ligament completing the arch above. The 

 skull varies remarkably in the different varieties of 

 the dog, attaining its maximum length in such 

 breeds as the Borzois and Greyhound \ whilst for 

 girth and heaviness the St Bernard and Mastiff, 

 Great Dane, etc., are conspicuous. The lungs 

 surround the heart, and breathing takes place 

 both through the mouth and nose, whereas in the 

 horse it is through the nose only. In order to 

 keep the temperature to its normal standard, the 

 dog pants, there being very slight perspiration
