having been lowered, the needle of the galvanometer is observed to be de-flected, through 80° for example. If now the pile is removed to a distance, CO (fig. 376), double that o{ co^the deflection of the galvanometer remains the same, which shows thatthe pile receives the same amount of heat ; the… … Fig. 376. pile is removed to three or four times the distance. This result, though?apparently in opposition to the second law, really confirms it. For at firstthe pile only receives heat from the circular portion ab of the side of thebox, while, in the second case, the circular portion AB radiates…
