Sir,
Using Tele-Radiesthesia, a form of telepathy by which information otherwise inaccessible may sometimes be obtained, I obtained the following figures for octane rating and “goodness” rating, which I presume means a balance between calorific value and octane rating. The figures were obtained on a form of Bovis Biometer which I specially calibrated for the purpose.
I obtained a number of figures for mixtures of base fuels with the high-grade petrols which are very informative.
I am, Yours, etc.,
F. W. CHAMPION.
