But thefe favlngs are far from being the^ only advantages that will be derived from the 

 Introdudion of thefe improvements in the management of heat: there is one, of great im- 

 portance indeed, not yet mentioned, which alone would be fufBcient to recommend the 

 very general adoption of them. As the heat communicated by fteam can never exceed the 

 mean temperature of boiling water by more than a very few degrees, the fubftances ex- 

 pofed to it can never be injured by it. In many arts and manufa£tures this circumftance 

 will be produflive of great advantages, but in none will its utility be more apparent than 

 in cookery ; and efpecially in public kitchens, where great quantities of food are prepared 

 in large boilers; for, when the heat is conveyed in this manaer, all the labour now em-~ 

 ployed in ftirring about the contents of thofe boilers, to prevent the vi£luals from being 

 fpoiled by burning to the bottoms of them, will be unneceflary ; and the lofs of heat occa- 

 Coned by this ftirring, prevented ; and, inftead of expenfive coppers, or metallic boilers, 

 which are difficult to be kept clean, and often ftand in need of repairs, common wooden 

 tubs may, with great advantage, be ufed as culinary vaffils ; and their contents may be 

 heated by portable fire-flaceSf by means of fteam boilers attached to them. 



As thefe portable fire-places and their fteam boilers may, without the fmalleft inconve- 

 nience, be made of fuch weight, form, and dimenfions, as to be eafily tranfported from 

 one place to another by two men, and be carried through a door-Way of the common width, 

 with this machinery, and the fteam tubes belonging to it, and a few wooden tubs, a com- 

 plete public kitchen, for fupplying the poor and others, with foups ; and alfo with pud- 

 dings, vegetables, meat, and all other kinds of food prepared by boilings might be efta- 

 bliflied in half an hour, in any room, in which there is a chimney (by which the fmoke 

 from the portable fire-place can be carried off) ; and, when the room (hould be no longer 

 wanted as a kitchen, it might, in a few minutes, be cleared of all this culinary apparatus, 

 and made ready to be ufed for any other purpofe. 



This method of conveying heat is peculiarly well adapted for heating baths : it is like- 

 wife highly probable that it would be found ufeful in the bleaching bufinefs, and in wafh- 

 ing linen It would alfo be very ufeful in all cafes where it is required to keep any liquid 

 at about the boiling point for a long time without making it boil ; for the quantity of heat 

 admitted may be very nicely regulated by means of the brafs cock belonging to the fteam 

 tube. Mr. Gott (hewed me a boiler in which flireds of Ikins were digcitiiig in order to 

 make glue, which was heated in this manner; and in which the heat was fo regulated, that, 

 although the liquid, never a£tually boiled, it always appeared to be uppn the very point of 

 beginning to boil. 



This temperature had been found to be beft calculated for making good glue. Had any 

 other loiuer temperature been found to anfwer better, it might have been kept up with the 

 fame f afe, and with equal precifion, by regulating properly the quantity of fteam admitted. 



I need not fay how much this country is obliged to Mr, Gott, and his worthy colleagues. 

 To the fpirired exertions of fuch men, who abound in no other country, , we owe one oi' 

 the proudeft diftinclions of our national character } that of being an enlightened and an 

 enterptifi^ng people.
