Abstract

1. The bactericidal agent extracted from horse leucocytes is apparently precipitated quantitatively by full saturation with ammonium sulphate. 2. The bactericidal agent is apparently precipitated by absolute alcohol, and is not rendered insoluble by a short contact with alcohol. The agent resembled in this feature certain enzymes which can be isolated and purified by alcoholic precipitation.
