X. 3109 - OBSERVATIONS OF SPARKS FROM VARIOUS MAGNETOS ON REVOLVING SPARK GAP APPARATUS

Herewith please receive sketches &c. of sparks obtained from a motor cycle type twin cylinder Dixie magneto.

These sheets are supplementary to our previous report on this subject, and the same explanations apply. They should be compared with the sheets previously given for the Z.A.2 Bosch magneto, remembering that from the Dixie there is no difference between the advance and retard positions.
