&s a Vehicle for conveying Heat, 55 



the labour now employed in ftirring about the contents of 

 thofe boilers, to prevent the victuals from being fppiled by 

 burning to the bottoms of them, will be unnecefTary, and 

 the lofs of heat occafioned by this ftirring prevented; and, 

 inftead of expend ve coppers, or metallic boilers, which are 

 difficult to be kept clean, and often (land in need of repairs, 

 common wooden tubs may, with great advantage, be ufed 

 as culinary vefTels; and their contents may be heated by 

 portable fire-places, by means of fteam-boilers attached to 

 them. 



As thefe portable fire-places and their fleam-boilers may, 

 without the fmalleft inconvenience, be made of fuch weight, 

 form, and dimenlions, 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 

 fleam- tubes belonging to it, and a few wooden tubs,) a com- 

 plete public kitchen, tor fupplying the poor, and others, with 

 foups; and alfo with puddings, vegetables, meat, and all 

 other kinds of food prepared by boiling, might be eftablifhed 

 in half an hour, in any room in which there is a chimney 

 (by which the fmoke from the portable fire-place can be car- 

 ried off) ; and, when the room fhould 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 likewife highly probable that it would 

 be found ufeful in the bleaching bufinefs, and in wafhing 

 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 fleam-tube. Mr. Gott (bowed me a 

 boiler in which fhreds of (kins were digefting in order to 

 make glue, which was heated in this manner; and in which, 

 the heat was fo regulated, that, although the liquid never ac- 

 tually boiled, it always appeared to be upon the very point 

 of beginning to boil. 



This temperature had been found to be beft calculated for 

 making good glue. Had any other lower temperature been 

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

 fame eafe, and with equal precifion, by regulating properly 

 the quantity of fleam admitted. 



I need not fay how much this country is obliged to Mr. 

 Gott .and his worthy colleagues. To the fpirited exer-
