• SINCE no measurements have so far been published, from any country, on colloidal systems using the air-driven spinning top of Henriot and Huguenard1, it is evident that the great importance of this remarkable tool has escaped the attention of most laboratories. This is especially surprising in view of the fact that any good mechanic can make the necessary simple equipment (a stator and a hollow rotor) for a cost of about two or three pounds, and that for most purposes no special precautions need be taken as to constancy of temperature or control of pressure. With much less than the pressure of air available in an ordinary garage, the top may spin at several thousand revolutions per second, producing centrifugal forces of the order of 105106 times gravity.
