Typewritten letter from Frederick Lanchester to Professor A.V. Hill, Secretary of the Royal Society

Scope and Content

Recounts history of the theory. Also criticises activities of the Royal Society in issuing “Notes on the preparation of papers communicated to the Royal Society”, and in other respects. The letter was not sent. It contains a typical account of the treatment of Lanchester’s circulation or vortex theory by official aeronautics (i.e. the National Physical Laboratory) [a theme to which Lanchester returns many times].
