    0* o A.D, 1850.—N° 13,061. De Fontaine Moreau s Impts. in Conducting, Consuming, $c.9 SmoJce. smallest basis of which receives the pipe conducting the smoke; secondly, of a cone, having its upper extremity bent towards the ingress of the smoke, and having the axis in the same direction as those of the pipes conducting the smoke from the chimney, and those of the pipes by which it egresses into the 5 main street pipes: this cone forces the soot^ to fall round these last pipes; thirdly, of an egress pipe, having the shape of an inverted 1, to facilitate the sweeping of a pipe when it is foul; fourthly, of a door, to allow the sweeping of the apparatus. From what has been herein described, it will be seen that the construction of houses already built is but very slightly modified; and 10 besides, that the whole of the heat which is lost in common chimnevs is sent back into the interior of the apartment by means of branch caloric pipes; it is therefore competent to say that they serve as calorifers. It is a known fact that the ordinary fire-places utilise only one-fifth of the heat developed by the combustion of a body, whilst, by the application of the present system, the use 15 of the calorifer herein-before described would utilise four-fifths of the caloric developed by the combustion of every kind of fuel, which thus alone effects a saving or rather a gain of three-fifths of the heat in favor of the present mode. New buildings will be more elegantly built, the roof better and more closely constructed, and more easily kept in repair, and the whole architectural 20 appearance will be preserved without being spoiled by the ugly sight of chimney tops. The speed of the draught for the smoke in the fire-places has been calcu¬ lated at nearly twenty-six feet per second, which corresponds to the maximum draught which takes place when the temperature of the gases in the chimneys 25 has reached six hundred and thirty-six degrees Fahrenheit, according to well known experiments. Second Improvement. To determine the general draught of the smoke. For this part of the Invention, it is necessary, after having found the velocity required by experi- 30 ment for burning the fuel in such a manner so as to determine a good draught, to obtain thus that velocity, which velocity, as stated before, has been laid down at twenty-six feet per second; that improvement is obtained by the following- rules :—-Firstly, that for ventilating coal mines in which the air circulates through numerous galleries, the length of which extends sometimes to thirty 35 thousand feet, the same air is forced in by means of a fire placed at one hun¬ dred and sixty to two hundred, or even three hundred and thirty feet, from the mouth of the mine, and from the open atmosphere, or by means of ventilators
