is intelligence. Alterations OF the mind manifestng

SIDES OF THE BRAIN UYEQUALLY DEVELOPED.
Now as regards other points, my pupil, DR.. Jackson,
has ascertained that Inflammation OF the rena pro-
duces amauross frequently in both eyes from dis
ease OF the right side OF the brain than the left side
Commissions of the eye take place very frequently in
cases OF disease OF the brain I have ascertaned in
taking up the published by Dr. Provost, Dr. Char
mel, and many others and myself have ascertained
that out OF CO in which these commissions OF the eye
occurred there AZ duo 70 the disease in the right
OF the BRAIN and 70 due to disease IN the left side
the brain. Therefore there great difference between
the two sides Of the brain you will IL ia as
regards general co1yusi0ns COender aud myself have
shown that general commissions Will occur ucl luQre
frequently in OF disease Of the right side OF The
brain 10 OF disease OF the left side. have
ascertaned that both Will occur far more frequently
in OF disease OF the right side Of the brain than I'm
OF disease of the extent and the location

right side the brain wall have the greatest power In
that respect, but II will also, II the patent does die
