nervous system. As I have indicated elsewhere, some concep- 
tion of a quantitative change in the amount of energy passing 
over a given nerve pathway after injury to another may have 
been present in Luciani’s mind years ago. 
Von Monakow’s work will take its rank along with other 
classical monographs on the nervous system—Francois-Franck’s 
“‘Lecons sur les Fonctions Motrices du Cerveau,’’ Luciani’s 
‘‘Cervelletto” and Soury’s ‘‘Le systeme nerveux centrale.” 
It is to be hoped also that the various illuminating addresses 
and lectures which were published during the years when the 
larger volume was in preparation will be continued long after 
its publication. 
The objection sometimes urged against works in the German 
language that American work does not receive proper consider- 
ation can scarcely be urged against von Monakow’s volume. 
American anatomists, psychologists, clinical neurologists, and 
surgeons are mentioned in the index of authors. The small 
number of American physiologists whose work is cited may 
perhaps be taken as index of the lack of interest in this phase of 
physiology which has been manifested by American workers.
