I2O Animal Morphology. 



The conjunctiva is also very well supplied with this 

 sense, and possibly bone and muscle in a very slight degree, 

 but bone more than muscle. 



Touch is the true prehensile sense of the body, as located 

 in the mouth or lips, the hands, and especially the tips of 

 the ringers and toes. 



But touch is something more than this. It has a unity 

 of sensation that gives a kind of ubiquity of feeling all 

 over ; one part cannot well be touched without the entire 

 body feeling a unity of pleasure or pain, of warmth or of 

 coldness, of creeping or curdling, according as its action 

 is excited by external sources, or by mental induction or 

 impression. 



In this general feeling, if it is brought into close collision 

 on the integument with the sense of force, for we have with 

 the impressions of softness, sharpness, smoothness, or warmth 

 or coldness, associated the feelings of resistance, hardness, 

 weight and burden, strength or vigour. 



This blending and co-relation of senses is beautifully 

 exemplified in the neural arch of the sense of force, which 

 further illustrates the blending of force and touch in the spinal 

 arches, and foramina, which subserve for the mutual dis- 

 tribution of both these senses, both centrally and peripherally, 

 and, in a great measure, has been the cause why senses so dis- 

 tinct in function and office, are so usually confounded as one. 



Though more directly relating to the brain, yet a word 

 may be said upon the three somatic senses the sense of 

 want, of force, and of touch. 



It is usual to consider the striped muscles as strictly 

 voluntary, with a certain amount of unwilled action, or 

 sustained excito-motory or spinal continuous action, biit for 

 initiation dependent upon the will. 



Very little reflection is required to rectify this palpable 

 error.
