these currents accelerate or retard the diffusion of albumen as 
they chance to move in the same or the opposite direction to the 
latter. Salt and water are filtered and diffused from the blood 
into the glomeruli of the kidney. The water rapidly rediffuses 
back into the denser blood, leaving salt behind and in more con- 
centrated solution in the kidney tubules. These return currents 
of water prevent the passage of albumen into the tubule, but not 
of the readily diffusible salts which still continue to leave the 
blood. The urinary secretion becomes thus progressively denser, 
and if by any cause the salt ccntents of the urine so nearly ap- 
proaches that of the blood that the water currents from tubule 
to blood-vessel cease, then the passage of albumen begins, and 
albuminuria is the result—Pfliger’s Archiv, Bd. 34, S. 431. 
LOCALIZATION OF FUNCTION IN THE Brain.—Goltz has long 
been the principal and worthy opponent of those who_ hold that 
the various psychical powers are distinctly and permanently local- 
ized in separate parts of the cerebral cortex. But the professor 
of physiology at Strassburg now concludes from the results of a 
new series of experiments that, though there can be no such 
minute distribution of function as Ferrier and others would claim, 
still there are manifest differences between the physiological 
_ properties of different cerebral areas. Goltz submitted a number 
ise but still he uses that sense ill. He treads the air with the
