| Description | Acknowledges previous correspondence, stating he will refrain from commenting until he has the particulars of the trials with the 3 instruments in question. Supposes Campbell Swinton will be able to purchase the instruments with the rotatory [?] contact breaker he previously proposed to him. He did not anticipate any advantage in using the primaries, stating the primaries must be in parallel with the secondaries. Supposes they can determine the relative quantities of electricity by the discharge of a Leyden Jar or of several combined in battery. |
