 of Broca, the following table (p. 96) is introduced

In this table the author summarises all the cases, recorded 

 up to 1906, in which the results of post-mortem examination are 

 stated. It will be noted by the reader that, of the 304 recorded 

 cases, but 103 possess the necessary details or exhibit sufficiently 

 circumscribed lesions, for their utilisation as evidence for or against 

 the doctrine of Broca. Of these 103 cases but 19 are in favour 

 of, and no less than 84 are against, the localisation of the speech- 

 centre in the posterior part of the third frontal convolution. 



The subject of aphasia is considered in detail from both 

 anatomical and clinical aspects. A complete bibliography from 

 1861 to 1907 is inserted. According to their relative importance, 

 more or less lengthy details regarding the cases recorded in the 

 several publications are inserted in a convenient form for reference. 

 Half the volume is devoted to a description of the personal obser- 

 ' vations of the author. The methods employed for the clinical 

 examination of aphasics are described, and detailed records of 

 44 cases are inserted. The book contains 175 illustrations, many 

 of which are full- page plates. 



The bearing of the views of Marie on the subject of cortical 

 localisation will now be considered. 



It must at once be confessed that the doctrines of Marie are 

 destructive rather than constructive from the aspect of cortical
