  • WOOL keratin is considered to be completely soluble in sodium sulphide. 30 ml. of 0·3 M sodium sulphide was added to 1 gm. carefully purified, wool, and this mixture was allowed to stand for about a month
  • After separating and washing with water, the solid matter was examined under the electron microscope
  • In order to determine the thickness of the membrane itself a collodion replica was made and gold-shadowed at a declination of 1 : 10
  • Fig. 3. is a shadow-cast replica, where part of the wool membrane has stuck to the collodion
  • In part it shows both the membrane and the corresponding impression and is in that way interesting purely from the electron-micrograph point of view
