Diese primitive Affäre gab Schwachparks, die nur in völliger Dunkelheit zu sehen waren. Hawksbee unterstufte später einen Globus aus Glas für die Kugel aus Schwefel und sammelte die positive Elektrik nach einem Leiter, der durch seidene Kabel von der Decke aufgehängt wurde, um dadurch zufriedenstellendere Funken mit der positiven Elektrizität zu erhalten, die damit erzeugt wurde.

Electro-therapeutics and X-rays . d mounted upon a revolving axis in a wooden frame and excitedby an application of the hands; the assistant so doing becoming the con-ductor for the positive current to escape. This primitive affair gave feeblesparks, which could only be seen in total darkness. Hawksbee later substi-tuted a globe of glass for the ball of sulphur and collected the positive elec-tricity upon a conductor suspended by silken cords from the ceiling, therebyobtaining more satisfactory sparks with the positive electricity thus gen-erated. medical electricity by Erb, published in this country in 1883, we find the following: Experiments, even the-latest ones inParis, have furnished no satisfactory results, and staticelectricity has still to conquer a secure place in electro- STATIC ELECTRICITY. 103 therapeutics. Within the past ten years static electricityhas, as all electro-therapeutists must admit, conquered andsecured a place in electro-therapeutics. The charge has been brought against static electricity that. Fig. 4.—The Latest Static Machine. This machine contains withinits case a small Wimhurst charger. When the large machine loses itscharge (which so frequently occurs in warm, humid weather), it can quicklybe restored by a few turns of the wheel, setting the small charger in motion, thereby saving the trouble of opening the doors of the battery and dryingthe plates or obtaining a charge by friction on the plates with the catskin. it resides upon the surface of charged bodies, that its influ-ence is superficial, and that it cannot affect deeper parts.Professor Norton has pointed out that not only is this state- 104 ELECTRICITY. ment disproven by actual experiment, but that it is unten-able in the light of electro-therapeutics ; that static electricity, when put to medical use, becomes kinetic (dynamic or cur-rent) electricity.
