McKinnells plan is shown in Fig. 4547. It consists of two concen-tric tubes with a space between them through which cold air enters. The inner tube, being protected by this air-space, becomes an outlet. A flange attached to the lower edges of this inner tube, and spreading outward below9 4 the inlet-space, directs the cold entering air toward theceiling and walls, and pre-vents it striking down uponthe heads of the inmates. The so-called Watsonstube is the simple devicewhich so commonly projectsfrom the roofs of root-housesand other similar
