HIS TORT of the SOCIETY 29 



dition. The produce was twelve gallons, of the fame quality *7 88 - 



with the fample. 



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

 corn fpirit 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 provifion for hogs, betide the wafh from 

 the ftill, which meafureo\ 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. 16. 



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

 confiding 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 (lone, which, at 1 d. 

 per ftone, will fell for L. 4. 



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

 each bufhel weighing about 3 ftone, which, at 1 d. per ftone, 

 will fell for 16 s. 



The Doctor, however, fuppofes, that the manufacturing of 

 the fpirit from carrots may be attended with more expence than 

 the manufacturing of it from malt ; but imagines that the greater 

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

 the faving of corn for other purpofes, is an object worthy of 

 attention and of encouragement.
