HIS TORT of the SOCIETT. 29 



dition. The produce was twelve gallons, of the fame quality i7S3. 



with the fample. 



In our examination of this fample, we found it refembled a 

 corn fplrit in flavour, but was equal to a corn fpirit of the beft 

 kind, and it was a proof fpirit. 



The refufe of the carrots weighed 48 ftone, which, added to 

 the tops and tails, made provilion for hogs, befide the wafh from 

 the ftill, which meafurec^ 1 14 gallons. 



From this experiment, Dr Hunter draws the following 

 comparifon between the diftillation of carrots and that of grain : 



20 tons of carrots, which will make 200 gallons of proof 

 fpirits, may be bought for L. 1 6. 



8 quarters of malt, or rather the materials for diftillation, 

 confifting of malt, wheat and rye, may be bought for L. 16, 

 and will alfo make 200 gallons of proof fpirit. 



The refufe from the carrots will be 960 ftone, which, at i d. 

 per ftone, will fell for L. 4. 



The refufe or grains from the malt, l^c. will be 64 bufhels, 

 each bufhel weighing about 3 ftone, which, at i d. per ftone, 

 will fell for 16 s. 



The Dodlor, however, fuppofes, that the manufacturing of 

 the fpirit from carrots may be attended with more expence than 

 the manufa(fturing of it from malt ; but imagines that the greater 

 value of the refufe may compenfate for that expence, and that 

 the favlng of corn for other purpofes, is an objefl: worthy of 

 attention and of encouragement.
