That discharged the acid which ts mixed with water goes into chemieal com- binatlon with the lead of the porous part of the plates.

When the motor is again start- ed the generator will send current into the_battery to recharge it. This charging action drives the acid in the plates back into the water of the electrolyte, and since the acid is very heavx the density of the electrolyte will be increased sufficiently to pre- vent the hydrometer bulb from sink- pounds to the square inch would have, if the 15-pound pressure of the sur- rounding air were removed, an abso- lute pressure of 82.5 pounds to_the square inch.

The cells in a battery. usually three or six. are all connected in series. and when one becomes discharzed all undergo a similar discharge. The hydrometer readings should be taken in each cell every time the battery is tested. and any considerable differ- ence between the readings of one cell is only common sense, “So long as an automobile or a pe- destrian is going in the direction in- dicated by the semaphore, neither can interfere with each other and each has its own right of way.
