PENRITH HERALD and EAST CUMBERLAND and WESTMORLAND NEWS. NO. 438-Sixth Week in Quarter Registered for Transmission Abroad. SATURDAY, FEBRUARY 7, 1874. PRICE 1D. AS IT IS. - "Sir, - A short time since, you did me the honour to notice my report on the adulteration of Caper, a black tea, much used in the northern counties. I have made a further analysis of other teas; the results I beg permission to make known through "The Times" . Of 18 samples, all were found to be adulterated. They were all artifically coloured or faced with Prussian blue, turmeric, and a mineral powder. The substances used in facing tea serve no useful purpose, but help to render practicable other more serious adulterations. I am, your obedient servant, ARTHUR HILL HASSALL, M.D. " 2, Adelphi-terrace, Strand, London, January 7th. To the Editor of "The Times". AS IT OUGHT TO BE. - "I visited the Docks, where tea imported by MESSRS. HORNIMAN, is in Bond. I took samples, which I analysed, and found genuine, and free from color. Now the public have the choice of tea perfectly pure (secured in packets), they will not be slow in deciding between it [and] that which is colored." (Signed) "ARTHUR HILL HASSALL, M.D." ============================================================
