 ductions are drawn from disease heing found in certain 

 convolutions, that the nerve influence of speech must 

 come from that locality. The witnesses do not agree 

 as to place and l^oundary, so it wdll be necessary to rule 

 them out of court until there is consistency and unanim- 

 ity in their testimony. Ferrier tells us that he removed 

 the whole of the occipital lobes of the brain of the 

 monkey, Jacko, and this excision impaired his ap])etite. 

 I have not the least doubt it would spoil the appetite 

 of any one thus deprived. (See Review in Journal of 

 Psi/chohgical Medicine^ January, 1878). I need not

 brain injury mentioned in Part I, and Vol. 1, of " Med- 

 ical and Surgical Cases in the recent American War." 

 Some had epileptic fits as a result ; others were affected

 had my attention senously drawn to this matter it was

 broken in the upper j>art of the frontal and occipital 

 bones on the right side. One of the nine pieces frac-

 bones, cut away the ragged edges of the membranes and 

 the lacerated brain substance. Consciousness returned 

 immediately. He did not lose a night's sleep, nor a meal 

 afterwards. No febrile symj^toms intervened, but a
