Brain, and being left alone without either Smoak or Heat, gradually and insensibly corrupts the whole Mass of the Brain, by which Means _Tobacco_-Smoakers are obliged to spit and expectorate continually. When the Brain is thus weakened by the copious Spitting excited by the narcotic Sulphur, neither the _Tonsils_ nor the _Thymus_, which are destined for imbibing the natural excrementitious Humours of the Brain, are any longer fit for that Purpose. When such an Accident happens, the _Tobacco_-Smoaker begins to yawn, to have a hoarse and shrill Voice, and a stinking Breath, like those labouring under a _Lues Venerea_. I think I have now sufficiently proved, that as _Tobacco_ is of a narcotic Quality, and its Fumes penetrate intimately into the Brain, so, of course, Smoaking must be more prejudicial than Snuffing. But, if People will still obstinately indulge themselves in the Use of this noxious Plant, all I can do farther, is to warn them of their Danger. [Illustration] A TREATISE ON _TEA_. I Have hitherto strenuously endeavoured to preserve the Health of the _Europeans_, by discarding and exploding the Abuse of _Tobacco_: But if any one should ask my Sentiments of _Tea_, which some Years ago began to be imported from _Asia_, and the _Eastern_ Countries, and which has Qualities quite contrary to _Tobacco_, since it prevents Sleep, and therefore is by some Authors highly commended as an excellent Cephalic, and very grateful to the _Viscera_, subservient to Nutrition: I answer, that no satisfactory Reply can be made, till we know the Genus and Species of _Tea_, and to what Species of _European_ Herbs it may be referred or compared; for _Tobacco_ is by us called the _Peruvian Hyosciamius_, but we give no Name of any of our Plants to _Tea_: Nay, it is not known, whether _Tea_ is what the _Greeks_ call Ποα, an Herb, or Θαμνίσκιον, a Shrub, which Words, according to _Ruellius_, _Morantha_, and others, are so confounded by _Dioscorides_, _Theophrastus_, and other Botanists, as to occasion great Disputes among the Learned. But the Authors, who have most faithfully collected whatever has been wrote upon _Tea_, either in the _Spanish_, _French_, _Latin_, _English_, or _Dutch_ Languages, are _Nicolaus Tulpius_, and _Nicolaus Trigautius_, from the Works of whom I shall enquire, _1st_, Of what Kind and Species the Herb _Tea_ is? _2d_, Whether _Tea_ is only the Produce of _Asia_, and whether it is ever found in _Europe_, or not? And, _3d_, Which of the _European_ Herbs may be most properly used in its Stead.
