glass tube was fitted, from which a horizontal tube proceeded so as to 
the glass bell into the interior of the porous cylinder, where it termin- 
ated in a plate of platinum or copper. Outside the porous cylinder 
ne circuit was closed, the liquid rose in the porous cylinder and flowed 
out from the horizontal tube into a weighed vess ae The results ob-

The quantity of fluid which flows out in ne times is directly 
proportion to the intensity of the current. 
2.) Under otherwise equal conditions, the quantities of fluid flowing 
out are independent of the magnitude of the conducting porous su urface.
