Obfervaiio/is. — It has long fince been 

 dem nftrated, that the draw of the feve- 

 ral kinds of corn, the bones of animals, 

 &c. are much ftionger, from the circum- 



be done by hand in the ufual way. To 

 effci5i this, the dimenfions of the vat, in 

 which the liulf for moulding is ufually 

 put, are to be, in length and width, ex- 

 aftly the fame as iliofe of the ftieet to be 



ftance of their being hollow than they made, and in depth sbout twenty inches, 

 would be if they were compaft bodies. In this vat, called the regulating refer- 

 having the fame quantity of mitter oniy voir, there is a frame or rim of wood made 

 in the conllruftion. So alfo in the cafe to Hide up and do*n at plcafure. The 

 of cotton wicks, thofe that are hollow, paper mould is alfo accurattly fitted to

This invention exhibits, undoubteoly, mould and frame may always move loge- 

 ingenuity in the application of a pi inci- ther. On the lide or end of the faid rcfer- 

 ple already known to the p.irpofes of voir, towards the bottom, is cut an aper- 

 common lite j but v^e fufpeit there are ob- ture by which the water may be dilcharg- 

 ftaclcs to the general reception of candles ed. The mcuih or opening is clofed by 

 thusmanufjftured. The procefs of mak- a lid or valve, which opens when the

 be tedious and flow, of comfe the expence ftiuts again as it dcfcends by the ailion of 

 will be much greater, and the coft to the the fame machinery. This being thus 

 confumer proportionally high. As we equipped, there is another ciiiern placed 

 have not feen any candle aftually manu- on one fide of the refcrvoir, having its 

 taftured on the plan, we cannot i'peak bottom nearly on a level wiih the brim or 

 with certainty J but it appsars that by upper I'urlace of the former one, to that 



the one may empty inro the other. In 

 the upper ciltern or feeder is fixed a fmall 

 awitator, which is confianily moving to 

 prevent the fubiidingor unequal mixing of 

 the pulp and water. Between the feeder* 

 ani legulatingrcfcrvoir there is a commu- 

 nicating fpout, which is opened or flint 

 alternately by a Aider. 



The wli. L being thus ready for work, 

 the regulating refer voir is filicJ with water 

 till it dii'charges at the moirh of the ex- 

 temal pipe; and ihen the mould being at 

 its loweli liation, has the wire luiface im- 

 r^.erkd below the level of the lurface of 

 the water, and the valve or lid which co- 

 vers the ipetuiie of the trunk being fliut, 

 prevents the efcape of the water trom the 

 inner refcrvoir. Whi!e the machine is in 

 this fiiuatiop, the lluice which opens the 

 communication between the leeder abtve

MR. JAMES MACKNAUTAN's (QUEEN- 



STRtET),yor a nevj Sionje, Kan^e, 



As we cannot explain the nature of this 

 invention, without the aid of figures, of 

 which our plan does rot admit, it will be 

 I'uflicient to lay, that the fpecification pro- 

 mifes not only a larger quantity of heat, 

 from the fame quantity of fuel, than in 

 common ftoves, but that the invention is 

 calculated to prevent, and even to cure 

 Imo.iky chimnie*. Tliefe ndvan'ages, 

 which all will admit to be confideral'le, 

 are to be efTctled by mcai.s of particular 

 confliu6lion, and the aid of re^iitcm or 

 regiiiatcrs.
