In nearly every case the puncture was found to be near the circumference of the area covered by the electrodes, which suggests that the surfaces of the electrodes, do not register properly, the contact pressure thus being unequal. In this respect the apparatus was not quite satisfactory.
Tests up to N.3 were carried out with the electrodes mounted on their original ebonite base, but on approaching 11,000 volts an arc was set up between the electrode supports. As the base was too short to allow of any adjustment the electrodes were remounted on a thick piece of fibre; the only thing available. This was used for the remainder of the tests.
