entering the same category with that creature who actually ex- 
ists and attempts to teach in a prominent school, and who is in 
the habit of calling his pupils “asses,” and “ block-heads,” and 
“ fools,’ and who threatens to throw them out of the third-story 
window, and to kick them down stairs. If I could have my

\ HAT les underneath the brain surface? Every wuere com- 
ing from the lower surface are white threads which gather 
into bands and pass downward and inward, and finally come 
out below in the form of nerves. These are the lines of com- 
munication by which messages from various parts of the body 
reach the brain, and along which the impulses are sent out from 
the brain to the body which result in speech and action. Imag- 
ine for a moment that from every part of the hand little threads 
pass up the arm and find their way to the brain, and there go to 
a special part of its surface and end. It can be seen at once 
that you have a little map of the hand laid out on the brain sur- 
face, projected there, to use the terms of the geographer; and in 
fact such a map of the entire body could readily be drawn on 
the brain surface if we could follow all the little threads to their 
ends. A sensation which has been sent in from the little finger 
has always gone to a definite place in your brain, and when- 
ever a message passes along that thread and goes to your brain 
you feel a sensation in the little finger. The thread goes along 
your funny-bone at the elbow, and if you happen to strike it 
there you send a message along it to the brain; but as all such 
messages have usually come from the little finger, the brain sup- 
poses that this one has also come from there, and this is the 
reason that, although you strike your funny-bone, you feel it in
