humane officer and wise and prudent general. Many a 

 battle has undoubtedly been lost for the want of a good 

 comfortable meal of warm victuals to recruit the strength 

 and raise the spirits of troops fainting with hunger and 

 excessive fatigue. 



But to return from this digression. The form of the 

 two principal boilers in the kitchen of the Foundling 

 Hospital is that of an oblong square ; that form which, 

 on several accounts, I have reason to think preferable 

 to all others for large boilers, but especially on account 

 of the facility of fitting them up with square bricks, and 

 of cleaning their flues, I first introduced in Ireland in 

 several fire-places designed for different uses, which I 

 fitted up as models, in Dublin, during the visit I made 

 last spring to that country on the invitation of my friend 

 Mr. Secretary Pelham. 



The first of these oblong square boilers is that which 

 is fitted up in the court-yard of the Linen-hall at Dublin, 

 as a model for bleachers. It is 8 feet wide, 10 feet long, 

 and 2 feet deep ; and it is furnished with a wooden 

 cover, which shutting down in a groove in which there 

 is a small quantity of water, the steam is by these means 

 confined in the boiler. This cover is movable on its 

 hinges, which are placed at the end of the boiler farthest 

 from the door of the fire-place ; and it is occasionally 

 lifted up by means of a rope, which goes over a com- 

 pound pulley which is fixed over the boiler at the top 

 or ceiling of the room. 



Under this boiler there are five flues which run in the 

 direction of its length, and are arranged and constructed 

 in the same manner as the flues of the new brewhouse 

 boiler which I lately fitted up at Munich. (See Fig. 21, 

 Plate V.) There are no flues round the outside of this
