Abstract
1. The effects of anaesthesia, temperature, pH, scalding agents and bleeding on the connection of the feather to the skin were studied. 2. Anaesthetics and increasing the temperature tend to loosen the feather; low temperatures and scalding agents tighten the connection, and bleeding is without effect while the effect of pH is variable depending upon the substance used. 3. In all local applications of drugs, no significant changes were found between living and slaughtered birds.
