works;* although, as the writer then first attempted to 

 show, SQch notions threw much light upon Cerebral 

 Physiology, and upon certain defects of Speech resulting 

 from disease of the Brain. f The writer's views were shortly 

 afterwards endorsed and extended by Dr. Broadbent, in 

 a valuable paper on the " Cerebral Mechanism of Speech 

 and Thought." } 



Soon, moreover, physiologists began in earnest to 

 search for such * Perceptive Centres ' in the cortical 

 grey matter. The first to do this was Dr. Ferrier, 

 though he makes no reference to the writer's views. He 

 took up the enquiry, perhaps independently — certainly 

 in a thoroughly systematic manner — and his results 

 deserve to be most carefully studied. § The notion 

 that there ought to be such ' perceptive centres ' evi- 

 dently commended itself to Ferrier, and, with charac- 

 teristic energy, he sought to throw light upon their locali- 

 zation, as he had previously — instigated by the views of 

 Hughlings Jackson — sought to establish the existence 



* No such conclusions were to be inferred, from the views 

 concerning Cerebral Physiology put forward in this country 

 generally. There is a philosophical opposition, in fact, between 

 them and doctrines which have been widely promulgated by Dr. 

 Carpenter (see an article on " Sensation and Perception, ' "Nature," 

 Dec. 23, 1869, and Jan. 20, 1870, p. 309).

+ " Med. Chir. Trans.," 1872, p. 180. Writing, indeed, in the 

 ** Journal of Mental Science " for April, 1870 (p. 23), Broadbent 

 says : — '* These convolutions then which rdceive central fibres, and 

 are bilaterally associated by the C. callosum, will constitute the 

 perceptive centres of Dr. Bastian." 



§ His first communication on this subject was presented to the 

 Eoyal Society, in April, 1875, and is to be found in Pt. IL of 

 that year's " Phil. Trans.," p. 415.
