experience. We know intuitively that if we do not turn, we will run into the 
obstruction. Intuition and organized memory are to my mind synonymous. 
We raise food to our mouth without consciousness, this is the result of habit. 
Habit is resultant from frequent repetitions which produce organized memory. 
Upon reflection we will find that comparatively few of our acts are conscious. 
Consciousness is a narrow wicket through we are connected with the outer world. 
• I spoke of a group of cells always vibrating to the same impression, and 
another argument in favor of that statement is the weariness which ensues upon 
protracted vision, hearing, taste, etc. If different cells responded to the same im- 
pression there would be no weariness. Cells do become tired and refuse to act. 
If we look upon one color continually it becomes blurred, one continual sound 
becomes indistinct, the odor from a flower is at first acute, afterwards less fra- 
grant. This would indicate two things: first that the same cells respond to the 
same impressions ; second that memory-cells must have rest. This rest is given 
by exercising different faculties and by sleep. But even in sleep this result is 
not always attained, for we often dream, and dreaming is cell activity during 
sleep. This is proven by the fact that we never dream of anything but past 
events. 
Physiologists have proved that during sleep, the brain is pale from want of 
blood, but if the sleeper dreams it is a brighter red. This would indicate an 
activity of the brain during dreaming. One of the peculiarities of dreaming is 
the extreme brief period which is required, also it takes no note of time or space. 
A drop of water has caused a dreamer to travel thousands of miles, to drown in a 
lake and to wake him up. A gentleman in this audience once dreamed "that he 
was walking through a street, and stopped before a hardware store in which 
were stoves arranged in tiers one above another ; while looking at them they fell 
with a terrific crash to the floor." Another student throwing a box down stairs 
caused this dream and awakened the dreamer at the same time. Dr. Carpenter 
relates the case of a clergymen who fell asleep in his pulpit, awaking with the 
idea that he had slept for more than hour; but on referring to his hymn book, he 
found that his sleep had lasted through the singing of a single line. 
As the hour is getting late I will omit any remarks on imagination, emotion 
and somnambulism. I wish to thank Col. Case and Mr. Warren Watson for the 
use of their libraries, also Dr. E. R. Lewis, Dr. J. T. Mitchell, and Mr. E. A. 
Cwin, for procuring the human brain which I will now demonstrate.
