Has the problem motion been solved at last? The of perpetual newest thing in dooks would seem to say so. This ingenious machine is kept in motion without spring, battery or wire, and derives its Jimpotus entirely from changes of temperature. It is said that a change of one degree will supply Jenough motive power for 120 hours Jof thotion (on this basis, the past two days, ranging from sharp frost to suffocating" damp heat, should keep the clocks ticking indefinitely). The principle is said to be very simple, the basis of it being a U-shaped glass tube containing mercury and a liquid gas. As the mercury expands or contracts with changing temperature it causes a swinging movement which, by means of a ratchet wheel, winds the clock.
The wear and tear on the mechanism is said to be so slight as to be practically negligible. if the clock does st for ever, it should certainly live a long time.
Restoring Lincoln Cathedral To-day the Duke and Duchess of York attended a service of thanksgiving in Lincoln Cathedral for the completed restoration of this, almost the most lovely of all cathedrals.
