Advantages of petroleum products .—‐Avoidance of: slaking, chemical reaction, adsorption, and solvent action; but longer soaking time is required. Paraffine and vaseline .—‐Materials having high fluidity when hot, and comparatively low fluidity when cold, permit surface of saturated test piece to be brought to definite and reproducible condition with all surface pores full. Paraffine may be used but vaseline is preferable because it undergoes no change of phase on cooling. Procedure and results .—‐A saturation procedure is described and comparative results given. Density and penetrativity of vaseline .—‐Sp. gr.23°/4° 0.8730, 32°/4° 0.8684, 42°/4° 0.8624. Penetrativity between 100° and 200°C = 0.063 ( t — 30) 2 cms./sec. A penetratimeter for determining the penetrativity of liquids is described
