N vs. Butler Mine company, 34 AtL Rep. 638 (Supreme Court of Pennsylvania, April 27, 1896). A foreign journal describes a watch made in Switzerland that calls out the hours in a voice like that of a human being. This mechanical curiosity is the invention of one Casimir Livan, who based its principles upon his knowledge of the workings of the phonograph. The case, instead of containing a striking apparatus, as some of the late costly watches do, is provided with a phonographic cylinder, which is fitted with a sensitive photographic plate, which has received the impression of a human voice before being inserted in by blades carrying paddles on their periphery, and a worm conveyer in the trunnion on a rotably-supporte- d shaft, geared to the driving shaft of the ap- paratus.

Generally speaking, the age of a boiler is by no means a criterion of the boilers safety. Boilers often explode when brand new, and, on the other hand, they often do faithful service when old enough to vote. It is a good plan, though, not to place too implicit reliance on them when they get very far along in years. These remarks are called forth by a recent boiler exploAbstract of Recent Mining Decisions. sion in the South, in which subsequent investigation showred that the boiler wras thirteen-handeIt was thirty Prepared for the .ming Review by years old and had been sold twelve Attorney-at-LaWestervelt, George times.
