 denj vere, and where they have diminifhed the confumption oi'

 mency of the weather is guarded agaiuft at lefs expence.

Conduction j Their conftruction is by no means expenfive ; they fave iron- 

 work, and require only bricks or tiles. Thefe are recom- 

 mended to be placed edgewife, and chofen as thin as poffible 

 for the inner walls. The circulating pipes are to be placed 

 fo, that rain falling down the chimney can never get into them. 

 The method of uting them is fo eafy, that in the largeft pub- 

 lic buildings one perfon is fufficient to light all the fires. All 

 the wood that can be contained in the fire-place, which is 

 very fmall, is to be put in at once ; it is to be fawn into pieces 

 of equal lengths; and as foon as it is burned, the Aider that 

 flops the communication of the circulating pipes with the chim- 

 ney is to be thruft in. By thefe means all the heat, which the 

 fuel is capable of producing, remains in the pipes, and ifTiies 

 out flowly, and only to diffufe itfelf in the apartment ; while 

 a fingle piece of wood, that had not burned at the fame time 

 with the reft, would oblige the Aide to be left open, and the 

 current of air neceflary for its combuftion would carry off into 

 the chimney the greater part of the heat produced.

Fig. 1, Plate III. reprefents a front view of the ftove: its 

 height is 164 centimetres (about 61 inches French), exclufive 

 of the vale, which is a feparate ornament, merely placed on 

 the top. 



Its breadth is 85 centimetres (about 31 \ inches.) 

 Its depth 58 centimetres (about 21 \ inches.) 

 The height may vary according to the fize of the apart- 

 ment, and be extended without inconvenience to two metres 

 (about 6 feet, 2 inches.) It may likewife be reduced, as I 

 have done for floves in a laboratory, which were to fupport a 

 fand bath as high as the hand. 



The other two dimenfions are determined ,by thofe of the 

 bricks employed to form the interior circulatory pipes, which 

 fhould be in certain proportions, that the fmoke may pafs
