IC Q. 'these carbons that you have produced, 1 they been electrically treated ?
A. They havo not.
17 Q. Do you wish to bo understood as saying these carbons wore frequently rubbed down on a plate or lap, as you style it, and then eleetricllay t, od before they were put in the lamps for use ?
A. Yes, cemented to tbe laps, rubbed down, or down, or both, to less than half their present size then usually treated, but sometimes not • alums’ ways treated. This was done in order to’ make t resistance higher.
18.,?- "’Imt Wa8 tllu electrical resistance of the Iran illiiminants used by you and Mr Sawyer in lamps?
A It was extremely various ; I know its lowest 1 was less than one ohm. I can only state the i.ighes sistuucu from recollection of surrounding circ stances, and comparative cross-setcion and lem-t' conductors. I place it, thus, as in our higher resist lam|», from thirty to fifty ohms; but nlthougl measured the resistances, I have no recollection o results of such measurements. In the treatment of carbon after they wore placed in the holders o lamps I havo reason to think and believe that I resistance before treatment was sometimes doubl
that, and I think as high as one hundred ohms. _
(Tho belief and tbe thought objected V Complainant’s Counsel.) —
19 Q. I place in your hands an electric lamp ; p examino it and state if you recognize it as one c lamps made by you and Mr. Sawyer?
