ANALYSTS’ REPORTS, The quarterly report of Mr. W. W. Stoddart, Analyst for the City of Bristol, states that he has examined sixty-four samples of food, &c. Three of the samples were of 80 bad a quality that adulteration240 TElE ANALYST, was suspected. One aample of butter submitted by a private individual waa genuine, but of bad quality and with a rancid smell. Five other samples were good.A sample of tea submitted by a private individual was good. Mr. W. F. Lowe, Analyst for Flintshire, reports that during the last quarter he examined 21 semples of which 7 samples were adulterated, viz.:“ out of 9 samples of spirits, and 2 out of 6 samples of milk-a large pementage, which ebows that Nr. Lowe’s recent appointment as analyst was made none too soon. We hope that his next report will show both an increase in the number of samples exmined and a decrease in the pementage of adulteration.Mr. West Knights, Public Analyst for Cambridge, in his report for the quarter ending September 30th, stated that twelve samples of food and drugs had been submitted to him for analysis, four of which he found to be adulterated. Out of four samples of buns three were genuine, and one was adulterated with alumin the proportion of 182 grains of alum per four pounds.The vendor, on being summoned, proved the use of a certain baking powder (which was found to contain 15 per cent. of bttrnt or dried alum) and was fined 1s. and costs. Out of four samples of baking powder, two, of the same make as the above, were adulterated with 15 per cent.of alum. Three samples of drugs, viz., spirit of nitrous sether, grey powder, and blue pill were found to be genuine. One sample of milk, submitted by a private purchaser, was found to be skimmed milk, diluted with 18 per cent. of water. No proceedings were taken against the vendor. ADULTERATED Hops.-The Transactions of the hfedical Society of Upsala contain an acoount of an ingenious fraud in the hop trade, said to be practised on 8 considerable wale in that oity.Hops which have already been used for making extracts, or for brewing in the ordinary way, are damped with a tincture of absinthe or wormwood, freed from spirit by distillation, re-dried, and then placed in the market as a genuine article with or without much bloom. Owing to their increased bitterness they often command a better price than unadulterated hops.ANSWERS TO COBRESPONDENTS.-T.
