 of the skin is unique in this fish.

 that it is for the purpose of cutaneous respiration." 



Cerebral Localization. 



In a paper read at the International Congress for 1892, Professor 

 Horsely places himself distinctly among those who admit that the re- 

 moval of a given motor area of the cortex alters the sensory, as well 

 as the motor reactions of the part of the body of which this area is the 

 "centre." Dr. Ransom reported, in the same connection, a case 

 where epilepsy began with tingling and spasm of the left hand which 

 resulted in slight tactile anaesthesia and diminution of motor power. 

 Operation revealed a cyst compressing the cortical centre of the left 

 hand. After recovery from the operation of removal, the area was 

 faradized without an ancesthetic. The results were contraction of 

 groups of muscles of arm and hand if the current was moderate. A 

 still weaker current produced sensation in those parts. After strong 

 induced contraction the voluntary power was weakened. 



Professor Ferrier, in his reply, cited several cases to prove that 

 there is no necessary relation between cortical paralysis and impair- 

 ment of sensation in any of its forms in the paralyzed parts. When 

 such an impairment occurs, it is a separable accident. He admits 

 that there is an intimate functional and probably an organic connec- 

 tion between the two kinds of centres. 



Professor Schafer has experimentally investigated the question 

 whether the removal or injury of the frontal lobes impairs the intelli- 

 gence, and has reached a negative conclusion. By destroying contin- 

 uity without removal of substance it found that the mitial shock was 

 largely obviated, and in monkeys a removal of the pre-frontal lobes 

 was nearly devoid of symptoms. 



A New Theory of Color Vision. 



Mrs. C. L. Franklin at the International Congress of experi- 

 mental Psychology, London Session, proposed a theory of color vision 

 which, it is claimed, avoids the difficulties of the Young Helmholtz 

 theory on the one hand, and the Hering theory on the other. In the 

 earliest stage of development, vision consisted of nothuig but a sensa- 

 tion of grey which was brought about by the action upon the nerve 

 ends of a certain chemical substance set free in the retina by the in- 

 fluence of light. In process of development of vision the decomposa-
