(73 to "Wheatstone bridge", line 25, inclusive, and insert: This modification being illustrated in Fig. 3, in which the devices already described are indicated by similar letters to correspond with those of Fig. 1. In this case it will be observed that the condenser which is being. charged fr an the battery B, through the resistance r, prefarably inductive and properly related to the capacity of the condenser, will store less energy when the sensitive device is energized by the rays, and its resistance thereby diminished. The adjustment of the various instruments may then be such that the receiver will be operated only when the rays are diminished in intensity, or interrupted and entirely prevented from falling upon the sensitive cell. "Or the sensitive device may be placed, as shown in Fig. 4, in a shumt to the resistance r, or inserted in any suitable way in the circuit containing the receiver, for exampl as illustrated in Fig. 5, in both of which figures the various devices are lettered to correspond with those in Fig. 1, so that the figures become self explanatory. Again, the several instruments may be connected in the manner of a Wheatstone bridge, as will be hereinaft er explained with reference to Fig. 2." Cancel claims 20 to 31 inclusive. We file herewith an additional sheet of drawings, showing the modifications described in the original specification. With the above amendment the application is submitted with the request that it be reconsidered on its merits. Кем. Родекстори atten for deila. 445
