In all instances a plurality of stippled or dotted coatings are applied. Each of these coatings should be successively applied over the entire surface of the skin and before the preceding coating is entirely dry; my practice being to start at one point of the skin; the upper left hand corner, for instance, and as soon as one coating has been applied, tostart'the second from the same point, and so on until the final coating has been applied. The 'dots or spots of the successive coating applications tend to run together quite promiscuously over the coated surface and this tendency of the dots or spots to run together, governed by the consistency of the coating body, its drying speed, the speed of its application, etc., determines the number of dotted or stippled coatings to jbev applied. In practice it, is desirable to only apply suflicient coatings to 'causethe dots to partially run together in anything but a regular manner and always in a way that 'will allow the base topartially be seen or grin through the dotted. surface; the dotted coat- ,ings thus applied creating a mottled effect. If

too many stippled or dotted coatings are applied,

of course, the skin [will have aflcomplete covering of the contrasting color and the base or ground coat willnot appear. v V
