amount and direction of the forces is altered, and then, of 
course, the changes that ensue are of a different kind. It is 
incorrect to say that no change has taken place except the 
escape or departure of an immaterial principle. The nerves 
no longer transmit, nor do the nerve-centres generate, those 
physical forces that determine the actions of structure that is 
alive. Dr. Lionel Beale discovers a complete circuit in the 
nervous system, strengthening the analogy with phenomena 
of an electrical kind. Other ph^^siologists trace a connec¬ 
tion between the consumption of phosphorus and the amount 
of thought performed by the brain. Here we have two sorts 
of incidents, the connection of which no physical investiga¬ 
tion can elucidate. The changes in the brain, and in the 
secretions, no doubt, follow chemical and other physical 
laws, and are simply the results of the direction and intensity 
of forces of the same character as those which preside over 
the material wmrld. They thus form fitting subjects for the 
research of the physiologist. But when we arrive at the 
question of why thought is connected with a brain, and why 
changes in the condition of that brain precede or accompany 
mental manifestations, our inquiry belongs to a totally 
different sphere. No polarization of particles, or oxidation 
of phosphorus can help us here. The ultimate cause is the 
will of Deity ; and if we seek for more we must do so in the 
direction of utility, and correspondence w ith that great scheme 
of creation of which so small a part is unfolded to our gaze. 
Let physical science give up the search for the wliy^ and 
tell \x?>Jiow, the universe proceeds. We start, and we conclude, 
with the conviction that an Intelligent and Benevolent Will 
is in all and over all; and in tracing the wonderful operation 
of what we call secondary causes, we exalt our conceptions 
of the only real cause that animates and guides the mighty 
whole.
