the two. Around the electric bed, or garden, was constructed a 

 frame-work, made of 2x4 inch timbers, on which were fastened 

 porcelain insulators, four inches apart ; a continuous, non-insulated 

 copper wire (No. 15) was strung on these porcelain insulators, as 

 shown in illustration, Fig. J , and the whole structure was then buried 

 so that the wire should be two inches below the surface of the ground. 

 Near at hand was a transformer, a small house in which were placed 

 switches, meters, voltmeter, ammeter, reducer and resistance lamps. 

 The interior of the house, together with the electrical instruments 

 may be seen as illustrated in Fig. 6. When the apparatus was put 

 in place, perfect control of the currents was obtained throughout the 

 whole time the experiment was in progress. Electricity was gener- 

 ated by the dynamo at the electric light station, the current was 

 alternating and was applied nightly, from time of turning on the 

 current at the generating house until after eleven o'clock, or about 

 four hours daily, from June 10th to October 1st, inclusive. 



The following table shows the variation of the current from June 

 10th, the beginning of the experiment, to July 13th, after which time 

 the current was at its maximum, viz : thirty-nine amperes, and 

 remained at this point from July 13th to September 30th. The volt- 

 age varied from fifteen as a minimum to fiftj'-three as a maximum.
