They who chuse to see a further Account of the singular Effects which this curious Fluid produces, may peruse what Doctor _Frobenius_, a _German_ Chemist, has published concerning it, in the Philosophic Transactions for the Years 1733 and 1741. But the most valuable Qualities of the AETHER are it's _medicinal_ ones; it having been found by repeated Experience to be an excellent Remedy in most _nervous Diseases_; particularly in FITS of all sorts, whether _Epileptic, Convulsive, Hysteric, Hypochondriac, or Paralytic_: In habitual HEAD-ACHES, GOUT, RHEUMATISM, PAINS IN THE, STOMACH, WINDY DISORDERS OF THE STOMACH AND INTESTINES, HOOPING COUGH, ASTHMA, PLEURITIC PAINS, and DEAFNESS, all which Diseases have, in a singular Manner, been removed by it; and that the Publisher may contribute all the Assistance he can in extending the use of this Medicine, the following Methods of applying, it are given, which have been attended with Success. _Particular Directions for using the_ AETHER. In the HEAD-ACH. A fit of the Head-ach is almost instantly removed by applying the AETHER externally to the Forehead, by means of a bit of Linen Rag, in the Manner hereafter directed for it's external Application. Or it may be applied to any other Part of the Head where the Pain lies, being first shaved, if necessary. If the Pain is violent, a Dose of it should be also taken inwardly. In stubborn Cases it will likewise be serviceable to snuff a little of the AETHER up the Nostrils, either alone or mixed with equal Parts of Lavender Water, _Hungary_ Water, or Brandy; or it may be more convenient to apply a bit of Linen Rag, wetted with AETHER, up the Nostrils. Any of these Means, or all of them, must be repeated if the Pain is so urgent as to require it. To cure this Disorder radically, when it is of long standing, and to prevent it's Return, the Medicine must be taken inwardly for a considerable Time every Night at Bed-time, or in violent Cases, every Night and Morning in a small Draught of cold Water, according to the General Direction for taking it inwardly, given p. 11. In some particular Cases, Vomits are very serviceable. A VERTIGO. A Vertigo, Giddiness, or Swimming in the Head, will generally be removed by proceeding in the same Manner as for the Head-ach. The EPILEPSY.
