[84] Professor Brande's Experiments. _Counterfeit Tea-Leaves._ The late detections that have been made respecting the illicit establishments for the manufacture of imitation tea leaves, arrested, not long ago, the attention of the public; and the parties by whom these manufactories were conducted, together with the numerous venders of the factitious tea, did not escape the hand of justice. In proof of this statement, it is only necessary to consult the London newspapers (the Times and the Courier) from March to July 1818; which show to what extent this nefarious traffic has been carried on; and they report also the prosecutions and convictions of numerous individuals who have been guilty of the fraud. The following are some of those prosecutions and convictions. HATTON GARDEN.--On Saturday an information came to be heard at this office, before Thomas Leach, Esq. the sitting magistrate, against a man of the name of Edmund Rhodes, charged with having, on the 12th of August last, dyed, fabricated, and manufactured, divers large quantities, viz. one hundred weight of sloe leaves, one hundred weight of ash leaves, one hundred weight of elder leaves, and one hundred weight of the leaves of a certain other tree, in imitation of tea, contrary to the statute of the 17th of Geo. III.[85] whereby the said Edmund Rhodes had, for every pound of such leaves so manufactured, forfeited the sum of 5_l._ making the total of the penalties amount to 2,000_l._ The second count in the information charged the said Rhodes with having in his possession the above quantity of sloe, ash, elder, and other leaves, under the like penalty of 2,000_l._ The third count charged him with having, on the said 12th of August last, in his possession, divers quantities, exceeding six pounds weight of each respective kind of leaves; viz. fifty pounds weight of green sloe leaves, fifty pounds weight of green leaves of ash, fifty pounds weight of green leaves of elder, and fifty pounds weight of the green leaves of a certain other tree; not having proved that such leaves were gathered with the consent of the owners of the trees and shrubs from which they were taken, and that such leaves were gathered for some other use, and not for the purpose of manufacturing the same in imitation of tea; whereby he had forfeited for each pound weight, the sum of 5_l._ amounting in the whole to 1,000_l._; and, in default of payment, in each case, subjected himself to be committed to the house of correction for not more than twelve months, nor less than six months.
