in tlu 1 left hemisphere, is not wholly confined to that side, and that the incompleteness of 

 the disability, and possibly also some of the apparent recovery, is due to the fact that the 

 intact right hemisphere has to sonic extent shared the special education. 



On the question of the separate cortical localisation of a "word-hearing" centre in the 

 left gyms angularis histology affords negative information; for although I have subjected both 

 hemispheres to examination I have been unable to detect any appreciable difference in the 

 two sides, either in regard to the arrangement of nerve fibres or nerve cells. Similarly 

 concerning a differentiation of the auditory area in correspondence with other faculties, such 

 as the recognition of tones of high and low pitch and of musical sounds, histology cannot 

 be of any assistance until more guiding clinical data are forthcoming.
