Accordingly, the scope of the investigation was enlarged to try the efficacy of trypsin in a variety of suppurative and sloughing lesions. This is a preliminary report of the results obtained.

John Hunter was the first surgeon to demonstrate the digestion of dead tissue by animal proteolytic enzymes. Since Hunter's time numerous proteolytic enzymes of both plant and animal origin have been discovered. However, there has been little or no work done to apply these in
