The contour of the cone at its base kept changing, while the lumpiness of the strand progressively disappeared and reappeared. Finally the strand broke into beads. The basal position of the strand, thus freed from the needle, gradually sank into the cone, which ulti- mately flattened out and disappeared. This phenomenon is similar. FIG. 15.
