ELECTRICITY AS A BRAKE.
A new electric brake, recently invented by an American, named Walcker, and which is already in use in America, was lately tried on a tramway between Turin and Piosassio, with remarkable results. It is reported that by means of this brake two cars, running at a speed of about twenty-two miles per hour, were stopped in the short space of six seconds, and within a distance of twenty yards. This, if reliable, is a great achievement certainly, and will doubtless lead to further and more extensive experiment, and possibly to its general adoption. The brake is at present being exhibited in the Turin Exhibition.
