TSE SOTAZ TIGER OF BENGAL. 7 



long fang-like canines seize, pierce, and hold the 

 prey. The sectorial, or scissor-Hke teeth, working 

 vertically against each other, serve to cut and 

 divide the flesh or to crush the bones. These move- 

 ments being effected by powerful muscles, which 

 pass under the zygomatic arches from high crests of 

 bone on the boldly-sculptured skull, and give the 

 peculiar aspect so characteristic of the camivora. 

 The tiger has a moderately well-developed brain of 

 the gyrencephalic type ; that is to say, the cerebral 

 lobes are convoluted, and extend somewbat over the 

 cerebellum, from which they are separated by the 

 bony tentorium, and are united transversely by a 

 corpus callosum. The special senses of heari ng_a3id — ■ 

 vision are acute, _wMlst-sniel-l- seeBa-3-4eHb'e~'C5mpaxa-

 vertical pupils ; the tapetum lucidum is of a greenish 

 hue, which gives the eye a peculiar and characteristic 

 glare when the pupil is dilated, and is often well 

 seen in the wounded tiger when crouching prepara- 

 tory to a charge. The tactile sensibility is acute, 

 and is especially marked in the so-called whiskers 

 upon the chin, lips, cheeks, and eyebrows. Each 

 hair has extreme sensibility at its root, and is move- 

 able by muscular fibres which form a portion of the 

 platysma myoides, and surround the hair bulb, which 

 is connected with a bed of glands and with the 

 nerves of the lip. They are, no doubt, of use as 

 feelers in their stealthy movements by night and
