The surfaces of brass and phosphorbronze are peculiar and the film formation is dependent more on the polar nature of the surfaces than on the chemical characteristics of the oil The authors' best thanks are due to Principal Lt. [...] Demulszbillty of the oils : Raw and neutral oils.—An important source of trouble in the lubrication of turbines and enclosed steam engines is the formation of sludge and deposits in oil pipes and coolers. [...] Kingsbury' defines this property as intensified viscosity of the fluid within the region of attraction of the surface molecules of the metal and has demonstrated the superiority of fatty oils over mineral oils for reducing the coefficient of friction under low speeds and heavy load conditions where oiliness comes into play. [...] This selective action depends on the nature of the polar part of the lubricant and also the nature of surface lubricated. [...] There was evidence of a decrease of saponifiable constituents in the bulk of the oil and a part of these was adsorbed on the surface.
