So that within the last few years, these, two very enterprising tradesmen, by combining their skill and vast resources, have been enabled to divide very large, rather unfair, and still increasing [profits. The brewer's chemist is said to be.com paratively a new man, but is withal 'ex ceedingly prosperous. He made his mark at the Paris Exhibition, and has achieved quite lately a front rank in com mercial activity. His assistance is declared to have long been sought and sorely needed, but now that his various appliances are brought into general use, the liquor trade (at one time rather precarious) may be conducted with the most complete and lucrative security. ; , My informant is enabled to supply a list of a few of the ingredients of this new chemical laboratory, and perhaps jyou will kindly tell me how far he is right, and f how far, wrong in the technical pbrtjon of i his details. At the head of the list stands bisulphate of lime, the? object of which is to correct what is ..called acetous fermentation^ one ton of the solution being considered!suffi cient to treat 3000,, tO: 6000 barrels ac cording to the strength of the liquor. This may be said tQ^e'the chief basis of the adulteration , and- it enables the ficti tious substitute to keep aa : -lojag- aB the genuine browst. ' '■''"' "* ! Next we find a, comparatively cheap, but very powerful artificial bitter as sub stituted for hops. One of the trade nWnes for this is Bavarian bitter. It is described as a drug of doubtful origin, but so potent in its effects, that lib of it equals 64lbs of the genuine article. Next we have what is called flavoring aroma, a technical name for which /is double flumulise, from Humulus,' the Latin name for hop. lib of this flavoring matter is equal to 361 bof hops. Next we are presented with what are called Burton Water Crystals: Their origin is mysterious, but they are highly recommended to the trade as imparting (like the lime) preservative qualities, im proving the color of the liquor, and giving that freshness and sparkling bril liancy which' beer drinkers generally so : highly prize.
