The lattermethod conforms more nearly to actual conditions inpractice and is perfarable; but the former method isthe simpler and more accurate and will be treated first.There are two ways of making the electrical test, thatemployed by Mr. H.G.Stott and that used by Prof.C.L.Norton.

The apparatus used by Mr.H.G.Stott is set up asshown in Fig. 11, page £6« The current is supplied bya shunt-wound D.C. exciter with voltage regulation.Where the pipe leaves the conduit, the openings shouldbe closed by means of a coupling and plug, and the cablesoldered thereon. The cable should not be soldered toa system completely installed without disconnecting thepipe in the conduit from the rest of the system, so asto avoid grounding the
