be the characteristic taste of all that has the tendency to contract whatever is the subject of its application. Thus galls, bark, rhubarb, camomile tea, &c. &c. are all bitter and astringent. It is, therefore, the immoderate use of such an astringent that ultimately relaxes and debilitates: like the too frequent bracing of a drum, or any other stringed musical instrument, destroys its tensity, the body is unnerved by the overstretching of its fibres. Although we sometimes differ with the celebrated Doctor in part of the conclusion he has drawn from his experiment, yet the following sentiments so perfectly coincide with all our observations upon India teas, that we are happy to have the opportunity of corroborating our own with the sentiments of so eminent a Philosopher. He says, from his experiments, "it appears that green and bohea teas are equally bitter, strike precisely the same black tinge with green vitriol, and are alike astringent on the simple fibre. From this exact similarity in so many circumstances, one should be led to suppose that there would be no sensible diversity in their operation on the living body; but the fact is otherwise: green tea is much more sedative and relaxant than bohea; and the finer the species of tea, the more debilitating and pernicious are its effects, as I have frequently observed in others, and experienced in myself. This seems to be a proof that the mischiefs ascribed to this oriental vegetable do not arise from the warm vehicle by which it is conveyed into the stomach, but chiefly from its own peculiar qualities." Dr. Hugh Smith, in his Treatise on the Action of the Muscles, justly says, that an infusion of India tea not only diminishes, but destroys the bodily functions. _Thea infusum, nervo musculove ranae admotum, vires motices minuit perdit._ Newman, in his Chemistry, says, when fresh gathered, teas are said to be narcotic, and to disorder the senses; the Chinese, therefore, cautiously abstain from their use until they have been kept twelve months. The reason attributed for bohea tea being less injurious than green is, being more hastily dried, the pernicious qualities more copiously evaporate. "Tea," says Dr. Hugh Smith, in his Dissertation upon the Nerves, "is very hurtful both to the stomach and nerves. Phrensies, deliriums, vigilation, idiotism, apoplexies, and other disorders of the brain, are all produced by the nerves being thus disarranged and debilitated. If the digestive faculty of the stomach be weakened, the body, failing of recruiting juices, must tend to emaciation, and the whole frame be rendered one system of distress and infirmity. The nerves, being thus deprived of a sufficiency of their animal spirits, must become languid, and leave every sense void of the first means of conveying to the mind the only enjoyments of our temporal existence.
