of the five-flue, pursues a parallel course with the first, and 

 gives out a current of warm air to the room at an aperture 

 H. This effect may be obtained in a much higher degree, 

 if the doors of the chambers and ash-hole are opened: 

 should the hand or face be then brought near, they would 

 be fanned with a stream of warm air, especially from the 

 upper chamber. 



By means of this stove I have evaporated milk to dryness, MHk evapo- 

 without burning or discolouring it; and have dried cherries, without bum- 

 plums, and other fruits, so as to imitate those which are »ng, and other 

 received from abroad. I have repeatedly dried colours and C g S ^; pl 

 the most delicate substances without the slightest injury to 

 them, even though the operation proceeded quickly.

 feet, and that of the flues 4 inches. The external part is 

 constructed of brick, and the internal parts of thin Ryegate 

 or fire-stone, except the top of the fire-place, which is a plate 

 of cast iron. Were it to be wholly formed of iron, its effects 

 would necessarily be more powerful.

 stoves of this kind may be advantageously connected with beextenued * 

 one or more furnaces for chemical or other uses. The fire- 

 place, brought out, either in front or on one side, by the 

 present position of its crown I, forms a reverberatory fur- 

 nace, or will make a sand-bath by reversing it. 



The space occupied by the fire-place in Fig. 1 may in 

 this be converted into apartments for evaporating substan-* 

 ces, or occasionally for cooling them by an opening at K to 

 admit cold air, while the warm air of the stove is excluded 

 by a register or door. The dotted lines show the manner in 

 which a second furnace may be connected by an opening 

 into the flue at L. 



In addition to the uses already pointed out, this stove Various pur-

Sin«e the stove is not limited to any certain dimensions, 

 it might be adapted to the drying of malt and hops, perhaps 

 of herbs, corn, and seeds generally. It might also be ac- 

 commodated to the purposes of the sugar-bakers, connected
