Added to their abuse of preparation may be that of their package. It is impossible but to know that their bad qualities must be considerably augmented by being so closely packed, for such a length of time, in such slight wooden chests, lined with a composition of wood and lead. Considerable quantities are likewise damaged by salt water and other causes, which, by the management of the tea dealers, are mostly mixed, and sold under different denominations. How the tea must be affected by the corrosion of the lead and tin by the marine acid, those of the least chemical knowledge will easily determine. To what danger must, therefore, the constitution of those who are in the constant habit of drinking such an empoisoned drug be exposed, may easily be imagined. Surely, when all these circumstances are considered respecting the pernicious mode of preparation, and particularly the poisonous qualities they are also liable to contract from the nature of their package, every person must be convinced to what a loss of health, if not of life, the constant use of such teas must expose them. Such evidence of their deleterious tendency is almost sufficient to alarm mankind against so prevailing an evil, without any further arguments; but as health is too precious not to require every possible proof that can persuade us to avoid what so immediately threatens our existence, the following arguments and testimonies of the bad qualities of foreign teas must not be omitted. Previous, however, to an investigation of their effects, it may be necessary to say a few words respecting THE MANNER OF USING.
