edin the present research. This is of importance in connection withthe question of the constants, olpserved at high temperatures. A standard resistance of 100 000 ohms was kept in parallel withone branch of the bolometer, see Fig. i, 5*1. By short-circuiting20 000 ohms of this resistance the… … cobtenta] Coustants of Spectval Radiation 19 was unbalanced, causing a galvanometer deflection which wasused as an arbitrary standard for testing the electrical sensitivityof the bolometer-galvanometer circuit. The galvanometer sensi-tivity was tested by throwing the switch K (Fig. i) to the right…
