lie relicability of the assump-tion that the energy is as the arc up to thirteen deg. deflec-tion—the result of the test in each instance proving decidedlyunfavorable to Mellonis doctrine—I undertook the construc-tion of a special ajjparatus for calibrating the galvanometerapplied to my thermopile.… … Mellonis method of calibrating galvanometers, described inthe work referred to; especiall}- since its supposed correct-ness has induced several eminent physicists to accept theassumption that the energies are as the arcs swept by theneedle from zero to 13 deg. deflection.
