Three pairs of lubricants were studied, the procedure being that described in the last paper. Briefly the clean cylinder was placed on the clean plate, both being of steel and warmed in clean air to above the melting point of the lubricant. Melted lubricant was then allowed to be drawn in under the cylinder by capillarity and a pool formed. The temperature was kept constant until equilibrium was reached, when the heat was cut off and the lubricant allowed to crystallise. The joint was broken at 18° C. Of the three pairs the first included substances, namely, palmitic acid and the paraffin C30 H62 , which seemed to be incapable of reacting chemically with each other; the second pair, palmitic acid and cetyl alcohol probably would react chemically; whilst the third pair comprised the paraffin C30 H62 and the ring compound phenanthrene.
