In order to present in a clear and terse manner the peculiarities andadvantages possessed by this recent invention, it is thought wise toappend the following abridged description. The coil consists of two separate secondaries with their primariesconnected in series. Each secondary has a high- and low-potential THE EONTGEN RAY APPARATUS. 167 termiual, due to tlie position aud tlie method of winding the primary is located outside the secondary winding. The secondariesare wound in single flat disks and lie in the same plane as the primaries;with this method of construction the discharge from the two terminals isvastly diiferent. The potential at the central terminal of the secondaryis extremely high, while that of the outer turns near the primary is verylow. By connecting the outer terminals of two such secondaries in series,the potential of t
