60 STRONG DRINK AND TOBACCO SMOKE. 



temperature of the wash in the rectifier acts as a refri- 

 gerator on the spirit and feints vapours, whilst, on the 

 other hand, the heat of this vajDour in the analyser 

 warms the descending wash, and causes it more readily 

 to part with its spirit. 



It has the additional merit of separating the spirit 

 from the wash more effectually than by the common 

 method. This is due to the fact that all the wash is 

 brought into contact with the steam in the analyser, 

 and such of the products as are condensed in the 

 rectifier, as '' hot feints," are again subject to the action 

 of the steam. 



Coffey's apparatus is capable of producing spirit with 

 only four and a half per cent, of water mixed with it ; 

 and when in good working order can exhaust from two 

 to three thousand gallons of wash per hour, producing 

 a spirit of a imiform strength, ranging from sixty-five 

 to sixty-seven per cent, over-proof. 



Mr. Young, of the Inland Eevenue, states that "the 

 quantity of spirits which may be produced from the 

 several materials used by distillers depends very much 

 upon the quality of the respective materials ; but it 

 may be assumed that, on an average, — 



1 quarter of Barley Malt will yield 1 8 gallons at proof.
