Owing to the protected position of the tip of the 

 Temporal Lobe, accurate limitation of lesions in this situa- 

 tion was found to be almost impossible. Hence, though 

 the ' centre ' for Taste is believed by Ferrier to be imme- 

 diately contiguous with that for Smell, viz., in " the lower 

 part of the middle temporo-sphenoidal convolution," at 

 the tip of the Temporal Lobe, he is unable to speak 

 with so much certainty as to this localization. " The 

 abolition of taste," he says, "always coincided with

 opposite side. (Ferrier.) 



destruction of regions situated in close relation to the 

 subiculum ; " whilst in favour of the part above defined 

 being the centre for Taste, he remarks that irritation of 

 this portion of the ' middle temporal convolution ' leads to 

 movements of the lips, tongue, and cheek pouches, which 

 he regards as " reflex movements consequent on the ex- 

 citation of the gustatory sensation." Destruction of this 

 region on one side produced temporary loss or impair-

 the loss of this sense became complete, double, and per-
