Another important improvement made by Weeks, is in admitting pure air from without, and warming it before it is diffus- ed through the house, creating not only a species of warm ventilation, but also caus- ing a gentle circulation of the air through- out the house—an idea entertained by the late Mr Penn in his system of heating, but which had not been found to operate satis- factorily in practice.—(Vide Penn's " Sys- tem of ;) To effect this, Weeks has introduced 2-inch pipes, in lengths of about 4 feet each, within the ordinary 4-inch heating pipes; one end of these small pipes is passed through the side of the 4-inch ones and opens into the house, while the other end also, passing through the side of the pipe in an opposite direc- tion, opens into the free air outside the house. As will be anticipated, these small pipes enter the house at distances of 4 feet apart; and the current of air is so great as to keep the leaves of the plants in constant motion, the heat averaging from 160° to 170°. This, although a highly ingenious plan, is not unattended with expense ; other contrivances will be hereafter noticed which act as well, with greater simplicity and at less cost. From " Newton's Journal" we extract the following,—part of the specification given by Weeks of his improvements in raising, lowering, or conveying heated water; these improvements are founded on the four following particulars: " First, in applying a cistern to the boiler for the purpose of supplying it with water, with- out making that cistern a part of the boiler, but only connected thereto by a tube; secondly, in a method of rai
