Abstract
The results recorded in the first part of this paper
indicate, in The first place, that the encephalitogenic action
of extracts of leucocyted and other tissues on the brain of the
rabbit is not due to proteolytic action per se, as the injection
of extracts of pancreas, as well as of commercial trypsin and pepsi
entirely failed to reproduce the characteristic syndrome in
the rabbit. The result with pancreatic extracts also proves that
a lipolytic ferment plays no part in the production of the
syndrome.
