The course which the two pipes take is downthrough the wooden partition separating the contiguouscompartments. Hot water circulates through these pipesand annular tubes, and it returns to the boiler after hav-ing given off its heat. The reversal of the current is ac-complished by allowing the hot water from the boiler toascend in a tube a few inches in length, on the top ofwhich there is a small valve. Having passed up this tube,and being unable to return to the boiler, the hot water ismade to circulate downward through the pipes. The an-nular tubes already referred to are about 3>^ in. in diam- i HORN nized. It would not require very great prescience toprophesy that one or more horrible accidents will occur inthe not very remote future, m which a good many liveswill be sacrificed and which will cause inexpressible suf-fering; all of which might be prevented by the adoptionof the simple device illustrated in the engravings, andwhich any company is now at liberty to use. A Ne\ System of Heating Railway Carriages. (From En,^i The efficient and economic heating of railway carriagesin northern climates has long been a vexed question, andmany inventors have endeavored to solve it; but the suc-cess which has hitherto attended their efforts has in mostinstances, been of a qualified character. It is satisfactoryto know, however, that there is now a prospect of the ob-ject aimed at being attained in a thoroughly successfulmanner. In this case the inventor is Mr. William Foulis,M. the Manager-in-Chief to the Glasgow Cor-poration as Commissi
