The Dynamic Analysis of Low-aspect-ratio Airplane Wings.

Shedlovsky's results,16 which differ from all others. There can be no doubt that most if not all, of these minima are spurious. One observation, which we have made may have an important bearing on this problem. In many cases, on addition of the first sample, the resistance of the solution drifted to lower values. The rate of this drift depended on the salt as well. as on the sample. In some instances the drift continued over a period of 24 hours. It may be noted, in this connection, that such drift was seldom observed with sodium salts and never with quaternary ammonium salts. It is possible that some of the minima that have been reported are reel; there is no doubt that some, if not many, are spurious.
