An emulsion of oil and water, made mechanically by stirring, has a pattern
approximately like that in a; and a similar emulsion, made by an electric mixer,
is indicated at £. These, as magnified to about 150 diameters, are taken from
photomicrographs in'Paints, Varnishes^ Lacquers and Colors^ 9th ed. (Washing-
ton, D. C.: Institute of Paint and Varnish Research, 1939), by EL A. Gardner,
figure 350, page aoa. At c is illustrated the action of an emulsifying agent in
dispersing oil particles in a continuous phase of water. This is taken from a
diagram, figure ia8, page 327, in Colloid Chemistry (Boston: Hough ton Miffin
Co., 1939)* by Robert J. Hartman. At </is diagrammed an oil-in-water emulsion;
and at * a water-m-oil emulsion. Both are adapted from Hartman, figure 127,
page 326. /J
