Pains, and Precautions observed by the _Chinese_, I doubt not but it would be equal to, their _Tea_; for if the same Measures are not taken in the Preparation of the same Herb, how is it possible, that it should produce similar and uniform Effects, especially if the one is gathered in the _Spring_, and the other in the End of the _Summer_: The one artificially dried in the House, and the other dried in the open Air by the Heat of the Sun; the one collected when it begins to appear, and other when the Plant is full of a roscid, sulphureous Dew, and bears Flowers, and Seeds. For this Reason, _Scherbius_ justly observes, "That when many Things concur to the Production of the same Effect; all these Things ought to be exactly the same." _Hoffman_, in _Comment. Lib. 7._ represents this Doctrine in the following accurate and beautiful Manner: "Individual Objects often appear to our Senses to have no Difference; whereas, a very considerable one is observed in their Effects. This Circumstance constitutes that Individuality, which cannot be described, and which, I remember, _Scherbius_, my old Master, used to illustrate by the following _Simile_: If a Bell-Founder should make twenty small Bells, of the same Metal, in the same Mould, at the same Time, and in the same Place; yet the Sound of no one of them will be perfectly similar to that of another. What can be the Cause of this Variation? The Artist, the Mould, the Metal, and the Fire, concur to produce the same Effects, which, however, is not obtained. Besides, if we were carefully to examine these Bells by the Sight, the Touch, the Weight and other Circumstances, we can discover no Difference; which, however, is sufficiently evinced by the Sound. Some Things, said my Matter, can neither be described, nor expressed, and of this Kind are these Differences. Perhaps, in this Case, there is not an equable Thickness of the Metal, because the Fire has not equably pervaded all its Particles. Perhaps the Surface is not every where smooth because the fused Metal might have been in some Parts more refrigerated than in others: and perhaps, there maybe other Variations; for, unless all Circumstances exactly concur, the same Sound cannot be produced in all the Bells." I have quoted this Passage from _Hoffman_, lest any Person, observing some Differences between our _Chamelæagnus_, and the _Chinese_, or _Tartars Tea_, should forthwith doubt,--whether they are Shrubs of the same Species, as I have already proved them to be. The _Chinese Tea_, therefore, and our _Chamelæagnus_, are Shrubs of the same Species; though, for the former, we go beyond the _Cape of Good Hope_, into _China_, cross the _Equator_ four Times in every Voyage, and expose ourselves to uncommon Hardships and Dangers, in order to bring Home the Leaves of an unknown Shrub, which has not the same Virtues and Qualities for which the _Chinese Tea_ is celebrated in _China_, and to which our _European Betony_ is preferable.
