To observe the original negatives it isnecessary to use a large stereoscope (Fig. 323). When making dental stereoradiographs, on filmsDental film held in the month during their exposure, the problem Bolder. of replacing the first film, after its exposure, with a second film, which will occupy precisely the sameposition as the first, is one fraught with great difficulties. In an effortto accomplish this the writer uses a Kny-Sheerer film holder and model-ing composition. The film holder, as I ns
