Van Gehuchten, A. La degenerescence dite retrograde ou degenerescence 

 WalI6rienne indirecte. Le Nevraxe, Vol. V, Fasc. I, pp. I-106, April, 

 1903. 



An extensive review of the literature on Wallerian degeneration, 

 followed by experimental studies on degeneration of peripheral and 

 central neurones. The degeneration which occurs between the point 

 of section and the perikaryon is cellulifugal and therefore typically 

 Wallerian. For this phenomenon the author proposes the same "de- 

 generescence walleriene indirecte." It occurs in both the central and 

 peripheral systems. In the former, certain fiber tracts undergo only 

 direct degeneration while others undergo both direct and indirect de- 

 generation. The author insists that it mu.st be known exactly which 

 tracts undergo indirect degeneration before the degeneration jihenom- 

 ena can be accepted as trustworthy evidence on certain physiological 

 questions. G. E. c.

The forebrain was removed from fifteen turtles and the forebrain 

 and thalamus from fifteen. After about three months degenerated 

 fibers can be demonstrated by Vassale's modification of Marchi's 

 method, these being confined to the brain if the forebrain only has 

 been removed, but extending through the whole length of the spinal 

 cord if the thalamus also is removed. This fasciculus thaiamo-spinalis 

 is diffuSjCly scattered through the fasc. longitudinalis medialis.

In this very brief preliminary communication it is mentioned that 

 the cervical sympathetic and the chorda tympani have opposite effects on 

 the blood vessels of the submaxillary gland, the former causing contrac- 

 tion of rhe vessels and the latter dilation. Two experiments were made
