e carry a varied stock of X-Ray Tubes suitable for inductioncoils or static machines. When buying tubes customers should givefull particulars of the exciting apparatus with which they are to beused. Being fragile all tubes are shipped at the risk of the purchaser,and we assume no responsibility for breakage. In the hands of a competent expert we claim unhesitatingly thatour X-Ray Apparatus w^ill produce unsurpassed results. A novice canhope for no real success, no matter how good his equipment may be. Upon request, we shall be glad to recommend the most suitableoutfit or apparatus to meet any stated requirements. JAMES G. BIDDI^E:. Oenersil Ssiles Agent. Philadelphia, November, 1903.

Figure i Roentgen Induction Coil. THE Induction Coil is now firmly established as the standard ap-paratus for X-Ray work. There was question when the rayswere discovered and for a long time afterward regarding themost efilicient and flexible apparatus for the generation of the discharge.The Static Machine, the Tesla or Thompson Coil, and the InductionCoil were the diflterent types of machines available.The Induction The Tesla coil was soon dropped, and the Static Coil the Thing. Machine, because of its advantage in direct electro-therapeutics divided honors with the Induction coil, which was foundbetter for radiography, but not superior in fluoroscopic work. Induction coils have been much improved and adapted to directelectro-therapeutics, so that the static machine yielding indifferent re-sults in Skiagraphy is now seldom installed in a first-class X-Rayequipment.
