wash to O, as marked by tlie saccharometer, by mixing a cer- 

 tain proportion of a very common root, prepared in a particu- 

 lar way, among tlie wai>h, or fermented worts, in a particu- 

 lar stanc of the fermentation. 



This year, 1803, he repeated his experiments upon several 

 kinds of roots ; and having transmitted the substance of the; 

 above paper, concerning the malt-tax, to a Member of Par- 

 li..ment, in order to verify his reasoning on the comparative 

 values of Kngiisli and Scotch barley, and also of Scotch bear 

 or big, he entered upon another series of experiments in dis- 

 tillation. 



With this view, he first malted 12 bushels of the weakest 

 bear, weighing only 36 pounds per bushel, or 12^^ stones per 

 Linlithgow boll. This bear was produced on his own glebe, 

 (parsonage lands), on a field which was in very high order, 

 and (on that account) had suffered much from the stormy 

 weather in tlie middle of May, and from the very severe frost 

 on the 13th of September, 1802, which checked its growth, 

 and rendered the grain of a lighter quality, and much smaller 

 size than it would otherwise have been ; but did not in the 

 least degree injure the germ, or hurt its powers of vegetation ; 

 for it made good seed, and malted perfectly well, though the 

 malt was weak. He selected this kind as a proper specimen 

 of what Scotch bear or big is in late seasons, and had it malted 

 under his own eye. He next malted a quarter, or eight bush- 

 els of bear, also the produce of his glebe, which was of a mid- 

 dling quality, weighing nearly 14^ stones per boll. He se- 

 lected this quality of grain, because it was of the precise weight 

 of middling beur (42 pounds per bushel), by the corn act of 

 1791. 



Afterwards, in order to get the best bear that Aberdeen- 

 shire produced last season, he applied to Messrs Black and 

 Company, brewers in Gilcomston, by Aberdeen, and he ob- 

 tained six bushels of uncommonly line malt, made by their 

 maltster, Thomas Pickman, an Englishman, from bear which 

 weighed i\G pounds per bushel. The malt had come out, in the 

 process of malting, only 4 per cent, and the bushel of dried 

 malt weighed 40 pounds, 8 ctmces. 



From the sane gentleman he also obtained six bushels of 

 m?k, from Scotch barley, which had come out 14 per cent, 

 in the process of malting, rather too much for the purpose of 

 distillation. The six bushels weighed 225 pounds of dried 

 malt, or 37^ pounds per bushel; and the barley weighed 48 

 pounds, wl-en unmalted, or 2 pounds more than the best 

 bisar weighed, per bushel.
