The Renown oil was a light machine oil espe-cially adapted for use in a type of bearing such as thatwith which the d;^^namometer was equipped, while the VaccuumA oil was a heavy crank case oil manufactured especiallyfor use v;hen the wearing parts are subjected to high temp-eratures as in the case of an automobile engine. Very good results were obtained .Tith the Pwcnovm oil asis shov/n by the curves, and the presence of the graphite inthe oil uncovered some unlocked results. It would naturallybe supposed that the coefficient of friction would vary di-rectly as the amount of graphite in the mixture, either in-creasing or decreasing by some fixed amount. This is no
