But we have seen; from the results of the before…mentioned experiments; that when the bread was baked under circumstances the most favourable to the economy of fuel; no less than 80 lbs。 of pine…wood were employed in heating the oven to bake 304 lbs。 of bread; which gives less than 4 lbs。 of bread to each pound of wood; consequently; TWO THIRDS at least of the heat generated in the combustion of the fuel must; in that case; have been lost; and in all the other experiments the loss of heat appears to have been still much greater。
A considerable loss of heat in baking will always be inevitable; but it seems probable; that this loss might; with proper attention to the construction of the oven; and to the management of the fire; be reduced at least to one half the quantity generated from the fuel in its combustion。 In the manner in which the baking business is now generally carried on; much more than three quarters of the heat generated; or which might be generated from the fuel consumed; is lost。

APPENDIX; No IX。
An Account of an EXPERIMENT made (under the Direction of the AUTHOR) in the Kitchen of the HOUSE of INDUSTRY at DUBLIN; in COOKING for the POOR。
May the 6th; 1796; a dinner was provided for 927 persons of Calecannon; a kind of food in great repute in Ireland; composed of Potatoes; boiled and mashed; mixed with about one…fifth of their weight of boiled Greens; cut fine with sharp shovels; and seasoned with butter; onions; salt; pepper; and ginger。 The ingredients were boiled in a very large iron boiler; of a circular; or rather hemispherical form; capable of containing near 400 gallons; and remarkably thick and heavy。 273 gallons of pump water were put into this boiler; and the following Table will show; in a satisfactory manner; the progress and the result of the experiment:
