Text Appearing Before Image:
while the single condenser in the baseoi the coil lias sufficient micro-faradcapacity l give a good fluorescence.Better and more- steady discharge is ob- lined by the employment of an addi-tional adjustable multiple condenser of at leasl 2.5 micro-farads. For a coil givingL2-inch spark we have to have twelveEdi -oil Laland cells. Where there is no other source of electricity at disposal,recourse to such a battery can be taken.It has, however, the inconvenience ofrequiring frequent replenishing of thecells.

If no lighting circuit is to hand,accumulators or storage cells are recom-mended as being a useful and sure sourceof current. For the same results asabove we use six storage cells, givingtwelve volts. The difference betweenthe two types of batteries is that thestorage cells can be kept operative bybeing recharged at stated periods at anyelectric light station, while in the pri-mary cells, the entire elements are con-sumed and have to be replaced. Inmaking these statements, high speed in-terruptions are contemplated, and weemploy a make and break wheel op-erated by a motor, which takes the placeof the vibrator on the coil. Two addi-tional storage cells are required to oper-ate the motor. If a lighting circuit is at disposal,which supplies continuous current, itwill be very convenient to utilize thissource of electricity for working theinduction coil, or with the help of motorand a good rheostat a Static machinemay be manipulated with good results.When making use of the constant incan-d
