It is seen tnat tHe battery wasfloating on the line. There was an ammeter inthe battery circuit; this was kept at zerothroughout ail runs. As the battery -rjs brousrhtto a fixed, point of charge before each run,current could not be taicen from it for startingthe engine; an external source, therefore, hadto be used. This consisted oi the drop over aloaa box, v/hicn wab in series with a lauip-racK:across a liu volt circuit; the drop over theloaa box, when no circuit v/aa being taiien bytne generator, was about 40 volts.
