Excision of Cortex .\s .\ Ci're for Insanity.' 



Six cases of chronic mania, dementia, etc., were operated by removal 

 of 2 cm. or more of the cortex, the areas corresponding to the seat of the 

 sense chiefly affected by hallucination. In five cases, amelioration, in 

 one, death resulted. The eft'ect seems t.o consist in the transformation of 

 impulsive mania into passive dementia, fre(|uently with removal of the 

 hallucinations. 



James Briefer Course in Psychology. 2 



Professor James is a teacher, and his much used work is conceived as 

 only a teacher could. It contrives to supply very much of the vivacity 

 and piquancy of personal instruction within the compass of a text l)ook. 

 Add to this the fact that Ire is especially alive to the prevailing tenden- 

 cies in psychological thought and we have a partial explanation of the 

 sudden success of a work which is neither logical in arrangement nor 

 faultless in psychical analysis. The briefer course seems to us a vastly 

 more usable book. The author describes it as three-fifths "scissors and 

 paste." These three-fifths have greatly gained, from the stndent's stand- 

 point, through both these modifying agents. The scissors have relieved 

 him of tapestries which would, in all probability have hung in shreds 

 about his hurrying feet, and the paste has been "mixed with brains." 

 The two-fifths not accounted for supply important physiological details 

 as to the sensory organs which American classical courses seem never to 

 adequately supply in the term or two of physiology. 



Many teachers will object to building up the fabric of an elementary 

 text-book upon such a ' \vf)rking hypothesis' as this: "Mental action 

 may be uniformly and absolutel)' a function of brain-action, varying as 

 the latter varies, and being to the brain as eft'ect to cause." (."onscious 

 processes are divided into sensation, cerebrati(jn, and tendency to action. 



The paragraphs on sensation fail to distinguish adequately sensation 

 and perception. Especially unsatisfactory is the discussion of externali-
