3. The visual word centre, appreciating written 

 language, in the left angular gyms, behind and above 

 the auditory word centre. 



Now, however, the searching analyses of Marie and 

 his pupils have raised very grave doubts about the 

 first and third of the above, and many neurologists 

 have agreed that Broca's convolution has no speech 

 function at all ; very few now defend the existence of 

 a separate visual word centre. 



Briefly, the contention of Marie and Moutier may 

 be put thus. Between 1861 and 1906, there have 

 been published 304 cases of aphasia with autopsy. 

 Of these 201 were useless and 103 were relevant.

The majority even of the nineteen cases allowed 

 by these writers they consider to be inconclusive 

 for various reasons. 



Two cases of Burckhart's are of sufficient surgical 

 interest to be worth quoting. In the first, he removed 

 5 grams of grey matter from the foot of the first and
