Frompractical trial with the hot-water method, I am perfectly sure that for heat-ing purposes it is entirely satisfactory, and is probably cheaper than W///mA- #// w/ .////// v/v/uAFig. 22.—Diagram of a sys-tem of heating by hot water. 702 THE ATMOSPHEEE. From information furnished by Dr. Covvles, and from my own ob-servations, I believe that the method used in the new waids of the BostonCity Hospital (steam) gives satisfactory results; results, so far as tempera-ture and ventilation are concerned, as good as, but no better than, thehot-water system. In some of the other buildings (other than wards) he thinks that steamwould probably be less expensive than hot water. A combination of steam and water heating may be made, which willavoid some of the objections of each. Such a system, as seen by the writer, consisted of a cylindrical stove,lined with fire-brick, and with nothing peculiar in its construction, exceptthat iron pipes containing water encircle the fire-pot within, in contactwith the fire. These pipes are continuous with a set which makes thecircuit of a room or rooms on the level
