connected witli the Leyden jars on aStatic machine, and if it is of propersize, the x-rays produced this way in thetube are most beautiful. Such perfection of apparatus with the jars of thelargest type, long- spark-gape, for de-veloping the x-rays, in such qnantitiesand of such penetrating qualities, makethem an indispensable diagnostic ad-junct in every difficult case. The properconnections with jars and static areshown in May issue of this Journal. pensed with, a current interrupter beingused instead, but an Electrical Condens-er, on account of its convenient formease of operation and power of generat-ing the highest degree of electromotiveforce may be added to our armamentar-inm. The Electrical Condenser was in-vented by Volta. in the later part ofthe eighteenth century, and it is so calledbecause its power of accumulating elec-tricity, which is received in repeatedcharges from other bodies until quanti-ties too minute in themselves to be oth-erwise perceptible, have been collected

The condenserof to-day is a great improvement uponthe original air condenser introduced byVolta, although the electrical laws arethe same. It is an apparatus whosefunction is to accumulate by induction alarge or small amount of electricity, de-pending upon the capacity of particularinstrument, on a comparatively smallsurface, and in short space of time.
