Dual Brain Action.' 



The case presented is of unusual interest in the fact that well 

 marked physical conditions are seen to coincide with the two mental 

 states. The patient, a sailor and a Welshman, was a noisy, de- 

 structive dement. He exhibited frequent alternations of condition, in 

 one of which he used his right hand by preference and spoke and un- 

 derstood English and was talkative, crafty and destructive. In the 

 second, or Welsh, condition he is left handed and apathetic, speaks 

 Welsh and that very imperfectly and scarcely distinguished one object 

 from another. In this case either hemisphere seems to be capable of 

 independent action, the change from one to the other being the occa- 

 sion of the change from Welsh to English and from left to right hand- 

 edness. The pulse curves in the two conditions are very unlike so that a 

 change in circulation may be suggested as as an occasion for the transi- 

 tion. It may be noticed also that an intermediate condition in which 

 the patient is ambidextral and used either language also occurs. It is 

 suggested that only the left hemisphere has been educated and that 

 this, rather than the unequal ravages of disease, accounts for the pa- 

 tient's greater proficiency in the English .stage.

The Diseases of Personality.^ 



The first edition of this translation we have already noticed. In 

 the present edition the translation has been revised and improved upon 

 and some typographical errors have been corrected. In the second 

 chapter we notice that the word "emotional" of the first edition has been 

 replaced by the term " affective." The author's preface to the fourth 

 edition is prefixed and the value of the work further increased by the 

 addition of a full index. 



The Cranial Nerves of Protopterus.^ 



This piece of work will interest comparative anatomists for reasons 

 quite apart from the critical taxonomic position of the type studied. 

 So exhaustive a study of any type and one based on so keen apprecia-
