doubtless with a large enough arena, and a sufficient time spent in alteration and adjustment, a model could be made to repeat the performance with regularity.[1]

In the case investigated by the author the normal flight path, when not subject to deviation, curved somewhat to the left; this is shown in Fig. 161 (a); the flight paths showing deviation are shown diagrammatically, (b),(c), (d), (e) and (f), the latter being paths when the aerodone is launched in excess of its natural velocity/

  1. There would appear to be no reason why the change should not be made to take place during troughing; except that then the velocity is higher and the stability is greater, it consequently takes more to divert the aerodone from its course.
