SYSTEMATIC ANALYSIS OF APPARATUS. 65 



and the haunch-bone, he causes a sensation that the 

 Mind perceives in the foot and lower leg, where the 

 branches of the nerve commence, and he says his foot is 

 asleep, when in fact there is nothing the matter with the 

 foot ; nor will rubbing the foot or lower leg, or anything 

 else, except removing the pressure, do any good. 



162. IlluS. IF AN ARM BE CUT OFF (, Fig. 1, PL 3) 



below the elbow, or the leg below the hip (5, Fig. 1, 

 PL 3), and the elbow struck or the nerve at x compress- 

 ed, precisely the same result will be produced ; the sen- 

 sation will appear to be where the nerves naturally com-' 

 mence, and the individual, through his sensations, will 

 appear to have a hand and foot. If he is asked with 

 his eyes shut to point out where his sensations seem to 

 be, he will accurately indicate where his foot or hand 

 would be, both in distance and direction ; and as the 

 stump is turned, so will it seem to him that the foot or 

 hand changes position. 



163. DISEASES OF THE GANGLIA OR NERVES SOME- 

 TIMES PRODUCE the most excruciating pains, which will 

 be referred to or perceived in parts perfectly sound. 



164. Illus. A LADY REQUIRED her physician to ex- 

 tract eight teeth, that, as she insisted, " ached." But 

 she was not relieved, for the teeth were sound, and the 

 disease existed in the nerves or Ganglia. 



165. IllllS. IN THE DISEASE NEURALGIA, NerVC- 



pain, or tic-douloureux, applications to the parts appar- 

 ently affected do not usually remove the pain, because 

 these parts are not usually the seat of the disease. 



166. PAIN PRODUCED BY PARTS DISEASED is not always 

 referred to them, but sometimes to others ; why, is not 

 known. 



167. Illus. PAIN PRODUCED BY SOME DISEASES OF 

 THE LIVER is frequently referred to a location under the 

 shoulder. 



168. Illus. PAIN PRODUCED BY INCIPIENT HIP-DIS- 

 EASE is frequently perceived in the knee. 



169. Inf. IT is BY NO MEANS CERTAIN that because 

 a part is painful it is diseased, or that pain is even pres- 

 ent, for it may seem to be in a part that is removed.
