Each time, however, that the small roller passes any point the band returns to contact with the large cylinder in advance of ils previous position. The diameter of the roller is so proportioned that the length of this advance is equal to the distance necessary for the substitution of the next picture. A reference to Patent 2,623 of 1890 will conclude the description of these more or less primitive diagram forms of apparatus. It is a method of substi- tuting one picture for another by means of sectional change over all its surface instead of displacing it as a whole, and the methods suggested are ingenious^ although the device apparently has not had a com- mercial career. The first stage of the History of Living Pictures is now at an end; the early short-cycle devices have been described, and though some of them have in their development attained a considerable degree of progress, yet without photographic aid it is most probable that they would not have reached so high a degree of efficiency. Thus, the final evolution-stage of the Living Picture commences with the rise of Chrono- Photography, and this subject must next be pursued.
