    7 Fergusons Improvements in Furnaces and Fire-places, §c. Having now described and particularly ascertained the nature of my said Invention, and the manner in which the same is or may be used or carried into effect, I may observe, in conclusion, that I do not con¬ fine or restrict myself to the precise details or arrangements which I 5 have had occasion to describe or refer to, as many variations may be made therefrom without deviating from the principles or main features of my Invention; but what I consider to be novel and original, and therefore claim as the Invention secured to me by the herein-before in part recited Letters Patent, is,— 10 First, the general arrangement and construction of furnaces or fire¬ places, as herein-before described. Second, the system or mode of constructing furnaces or fire-places wherein passages are formed for the introduction of air into the main flue or flues, such passages being carried along close to the main flue 1 o passages, from which they are separated by very thin partitions, so that the air may take up the heat radiated from the main flues, as herein¬ before described. Third, the system or mode of arranging and constructing furnaces or fire-places wherein a hanging or intermediate bridge is combined with 30 or inserted in a mixing or combination chamber, for the commindino* G O of the gaseous products of combustion and air. Fourth, the system or mode of arranging and constructing furnaces or fire-places wherein the gaseous draught current takes a descending and ascending or tortuous route through a mixing or combination 25 chamber. Fifth, the application and use of brick or earthenware ducts or passages for heating the air prior to entering the furnace or flue. In witness whereof, I, the said John Ferguson, have hereunto set my hand and seal, this Twelfth day of May, in the year 30 of our Lord One thousand eight hundred and fifty-four. JOHN FERGUSON, (l.s.)
