_The Use of these Citations is not the least Innovation, and extremely commodious and easy: but were there only a single Reader likely to be puzzled by them, I ought not to omit this Explanation of them, as I can expect to be generally useful, only in Proportion as I am clear: and it must be obvious, that a Desire of being extensively useful is the sole Motive of this Work. I have long since had the Happiness of knowing, that some charitable and intelligent Persons have applied the Directions it contains, with extraordinary Success, even in violent Diseases: And I shall arrive at the Height of my Wishes, if I continue to be informed, that it contributes to alleviate the Sufferings, and to prolong the Days, of my rational Fellow Creatures._ _N. B._ A Small Blank occurring conveniently here in the Impression, the Translator of this Work has employed it to insert the following proper Remark, _viz._ Whenever the Tea or Infusion of the Lime-tree is directed in the Body of the Book, which it often is, the _Flowers_ are always meant, and not the _Leaves_; though by an Error of the Press, or perhaps rather by an Oversight of the Transcribers of this Version, it is printed _Leaves_ instead of _Flowers_ P. 392, as noted and corrected in the _Errata_. These Flowers are easily procurable here, meerly for gathering, in most Country Places in _July_, as few Walks, Vistas, &c. are without these Trees, planted for the pleasant Shade they afford, and to keep off the Dust in Summer, though the Leaf drops rather too early for this Purpose. Their Flowers have an agreeable Flavour, which is communicated to Water by Infusion, and rises with it in Distillation. They were, to the best of my Recollection, an Ingredient in the antiepileptic Water of _Langius_, omitted in our late Dispensatories of the College. They are an Ingredient in the antiepileptic Powder, in the List of Medicines in the present Practice of the _Hotel Dieu_ at _Paris_: and we think were in a former Prescription of our _Pulvis de Gutteta_, or Powder against Convulsions. Indeed they are considered, by many medical Writers, as a Specific in all Kinds of Spasms and Pains; and __Hoffman__ affirms, he knew a very tedious Epilepsy cured by the Use of an Infusion of these Flowers. I also take this Opportunity of adding, that as this Translation is intended for the Attention and the Benefit of the Bulk of the Inhabitants of the _British_ Empire, I have been careful not to admit any Gallicisms into it; as such might render it either less intelligible, or less agreeable to its Readers. If but a single one occurs, I either have printed it, or did intend it should be printed, distinguishably in Italics. _K._ __Introduction.__
