In view Of the evidence OF disease herewith pre-

upon palpahle lesion. but prepared to give
to the exact lesion that ia found in any par-
ticuar form Of insanity. Il, however, you WI:
ptre the photo-nic1ograpLs taken from sections Of
brain remored from the Of Ecute unnia you
will observe striking similarity; and there liz also
vast difference between these and the one removed
from the brain in the chronic state Hence am led
to infer that further Investigation will throw more
light upon these points, and that eventually sinu
have thorough knowledge Of tho pathology OF in

On motion OF Mr. Harvey Thompson, vote of
thanks WAS rendered to DR.. Kempster for his
able and interesting paper, which was ordered

After adjournment, the members Of the So
ciety devoted considerable time to an inspection
Of tho slides and photographs presented and
loaned BY Prof. Kemrster, and the examination

meetings Of the Society will be resumed in
