The same test was repeated, with all the conditions similar except that the temperature of the room was raised to 38° C. (= 100° F.) before the oil was placed on the glass; but the glass was allowed to remain in this temperature also for 30 minutes. The results of both experiments are shown in table IX. TABLE IX.

Thus it is seen that the third and fifth columns of figures denote the relative adhesion of the oils, approximately according to the value of the figures; while the fourth and sixth columns exhibit their relative cohesion, and absence of adhesion, approximately according to the inverse value of the figures. Thus the tendency of the oil to spread, in the warm temperature to which time keeping mechanisms are frequently subjected, is indicated.
