Another very important organ in the pccuL'ar mode of 

 life to wliich the Mole is subjected, is the elongated 

 muzzle. This part projects considerably beyond the 

 maxillary bones, and consists of tlic cartilages of the 

 nose, perforated by tiie nostrils, which are perfectly

 prehension, for seizing and bringing to the mouth its 

 food and other matters ; and as a boring instrument for 

 perforating the earth, and thus acting in conjunction 

 with the hands in the process of excavation. But 

 whilst the external appendages to the organ of smell are 

 thus beautifully developed for purposes remote from its 

 primary object, the sense itself and its more immediate 

 seat are found to occupy a very prominent place in the 

 sentient organization of the animal. The sense of sight, 

 so important to most others, would in the present case 

 be useless, at least during by far the greater portion of
