Adsorption tests were made on four large synthetic and three natural quartz crystals to see if surface defects might be detected by subsequent autoradiography techniques. The adsorbent used was radioactive Cs137 in a solution of Cs 137Cl. Natural quartz crystals adsorbed more cesium than the synthetic crystals. Certain surface defects were made evident by this method, but twinning features could not be detected.
The wet ashing of oils and aspbaltenes by sulfUric acid, percbloric acid, and nitric-sulfuric acid techniques is discussed and compared. A simple sulfuric acid=nitric acid technique which has been found to be satisfactory for these substances is described.
