to correspond with that of the same planet when near its 

 opposition. It cannot therefore be expected that the orbit 

 laid down in the chart will be verv correct : but, as great 

 care has been taken to lav down all the stars as far as those 

 of the ninth magnitude with as much accuracy as possible, 

 it is hoped this small map will be found particularly useful 

 to those who mav not be provided with ins.ruinenti for 

 takins: right ascensions and declinations, but who, being 

 provided with a good telescope, may wi!.h to find it; which 

 bv help of this chart and a good general atlas or pair of 

 globes they may easilv do, bv first finding some (jf the prin- 

 cipal stars and then those of a smaller magnitude, by \\ hich 

 they will be enabled to find those laid down in th.s map; 

 and, by comparing their positions with their apparent places 

 in the heavens, will be soon led to discover the planet by 

 its motion among them. The planet is a little brighter 

 than those marked in the map of the eighth magnitude; 

 and, if the places of these stars be carefully obser\ed, can 

 hardly be mistaken." 



IX. Description of improved Malt Kilns for drying Mult 

 by heated Air*. 



JC iG. 1. (Plate TI.) front view of the malt kiln aa, the 

 furnace door, b, the fire, through which the air rises, the 

 grate being of the common kind, c a cast iron tube, which 

 passing through the fire, and havini: one end open to the ex* 

 ternal air, and the other open into the kiln, conveys heated 

 air to the grain, d, a flue around the fire, in which air is 

 also heated and conveyed to the grain, e, the ash pit. f, 

 the chimney. 



Fig. 2. aside view of a malt kiln, in which the grain is 

 drieu by heated air, as in fig. 1, but in which the air neces- 

 sary tor combustion of the fuel discends through the grate. 

 a, the fire, b, the grate, c, the door of the furnace, d, the 

 door of the a-^h pit. e, the ajr tube, f, the ash pit. g, the 

 lend of the air tube entering the space below li, the kiln 

 head, which is coinposesl of tiles perforated with small 

 holes, lying on the joists i, and supporting the malt k. II, 

 the windows, through which a current of air may freely en- 

 ter or escape. ?n, the air outlets above. If a distiller finds 

 his buildings so relatively situated that he can lead the air 

 cylinder of his malt kilu through the flue of his still or 

 iTiash boiler furnace, the expense of fuel for drying malt 

 may be saved.
