apted to deliverheavy discharges to the X-Ray tube, so that the radiographs can betaken in the shortest possible time. Also, these coils are most suitable for the long and continuousrunning required in therapeutic work, and are thus admirably adaptedfor heavy radiographic as well as therapeutic work. We shall bepleased to correspond with physicians interested in the apparatusadapted to both uses, and will gladly assist them in the fulfilment oftheir own particular conditions. We are prepared to give a course of instruction in its use at ourlaboratory, to those of our patrons who can come to see us. Thosewho are unable to come to Philadelphia we will assist in learning theuse of the apparatus by the correspondence method. If the reader is not interested in the more recent and difficultradiographic work but wishes a machine of moderate size we shall beglad to furnish him information bearing on the subject if he willmake inquiry of us.

JAMES G. BIDDLE, III4 CHESTNUT STREET, PHILADELPHIA. Roentgen Induction Coils of large capacity. The induction coil shown on page 6 is adapted for use on either thedirect or the alternating current with the Roentgen electrolytic inter-rupter. It is provided with series spark gaps, operating switch, re-versing or pole-changing switch, rheostat for regulating the currentand discharge rods for measuring the resistance of the X-Ray tube. It will be noted that the rheostat is provided with a graduatedscale for comparing the currents used at different times. The wood-work of the coil is of the finest polished mahogany,that of the table is of cherry. Polished hard rubber insulation is usedwherever high insulation is required, and the best of construction andfinish is employed throughout. This apparatus is capable of doing the heavier kinds of radio-graphic work required of an X-Ray expert, as well as the lighter the-rapeutic work, for which latter, however, it is not quite so satisfactoryas
