7^ appendix. Feh. 



SIX bushels, and then three bushels, of very good malt, made 

 from English barlej, that weighed 51 pounds per bushel. The 

 first six bushels were ground on a steel mill in the country, 

 and weighed, before being ground, 25 7 f poiinds averdupois, or 

 42 pounds, 14'^- ounces per bushel. The next three bushels, 

 or iiS.j pounds of ground malt, were made from the same bar- 

 ley, and at the same time ; but Messrs Black and Company 

 were so obliging as to grind them on their o\mi mil], whi^.'i 

 was a great advantage. A quantity of the wash extracted 

 from the first six bushels, overflowed the fermentitig tun, 

 when the writer of this paper was obliged to be absent a few- 

 hours ; which occasioned him to repeat the experiment with 

 other three bushels of this excellent malr, ground in the best 

 manner. This malt had come out 9 per cent, in the process 

 of maltin-g. 



He shall now state tlic results of tlicse experiments, both as 

 to the quantity of spirits contained in the boll of grain (in the 

 two first cases), and in that contained in the boll of barley or 

 bear, in the four last experiments. For, without stating in 

 these cases, both the quantity produced from the boll of malr, 

 and what m.ust also have been produced from the boll of grain, 

 the comparative values of all these different kinds, can not be 

 accurately ascertained. 



1st, The 12 bushels of weak bear, that weighed 36 pounds 

 per bushel, produced exactly 124- English wine gallons of proof 

 spirits. This is 6-^- gallons of proof spirits, or ^-'^ gallons of spi- 

 rits, I to 10 above hydrometer proof, from the boll of 6 bushels. 

 2dly, The middling bear produced 11^ gallons of proof spi- 

 rits, from the quarter, or 8/^ gallons, from the boll, i to 10 

 above proof. 



3dly, The malt from the best bear produced 127% gallons, 

 from the six bushels of malt. This is 123 gallons of proof 

 spirits, from the boll of bear, or 114 gallons, i to ro over 

 proof. It is here a very curious fact, that a bushel of bear or 

 big, weighing 46 pounds, should produce almost exactly dou- 

 ble the quantity ot spirits, that weighed only ^6 pounds. 



4thly, The six bushels of malt from Scotch barley, pro- 

 duced 1 3 y gallons of proof spirits ; and, after allowing for 

 what it had come out in the process of malting, the produce 

 from the six bushels of Scotch barley, is ij^^^ gallons of proof 

 spirits, or exactly 14 gallons of spirits, 1 to lO over proof. 

 The superiority of mait made from Scotch barley, is here ve- 

 ry evident ; for 225 pounds of this malt, though it had come 

 out a little too much in the process of malting, jnelded above 

 a ^ allon of more spirits than had been obtained from 243 pounds 

 of malt made from tb.e bust bear. But the progressive in-
