Abstract Part I.—The Latent Period. When a lubricant is applied to a solid surface the friction, with certain definite exceptions, does not at once reach its steady value, but starting from a relatively high level, falls in longer or shorter time to a constant value. The existence of this latent period has been known to us for a long time and put aside for further enquiry, the values of μ considered in the earlier papers having always been the final or “steady” values. The latent period seems to be merely the time occupied in the orientation of the molecules of the lubricant at the solid face.
