Sponge is also applied on these Occasions in another Manner. When there is no Room to convey it into the Gullet, because the obstructing Substance ingrosses its whole Cavity; and supposing it not hooked into the Part, but solely detained by the Straitness of the Passage, a pretty large Bit of Sponge is to be introduced towards the Gullet, and close to the obstructing Subtance: Thus applied, the Sponge swells, and thence dilates that Part of the Passage that is above this Substance. The Sponge is then withdrawn a little, and but a very little, and this Substance being less pressed upon above than below, it sometimes happens, that the greater Staitness and Contraction of the lower Part of the Passage, than of its upper Part, causes that Substance to ascend; and as soon as this first Loosening or Disengagement of it has happened, the total Disengagement of it easily follows. Sec. 415. Finally, when all these Methods prove unavailable, there remains one more, which is to make the Patient vomit; but this can scarcely be of any Service, but when such obstructing Bodies are simply engaged in, and not hooked or stuck into the Sides of the _Oesophagus_; since under this latter Circumstance vomiting might occasion further Mischief. If the Patient can swallow, a Vomiting may be excited with the Prescription No. 8, or with No. 34, or 35. By this Operation a Bone was thrown out, which had stopt in the Passage four and twenty Hours. When the Patient cannot swallow, an Attempt should be made to excite him to vomit by introducing into, and twirling about the feathery End of a Quill in, the Bottom of the Throat, which the Feather however will not effect, if the obstructing Body strongly compresses the whole Circumference of the Gullet; and then no other Resource is left, but giving a Glyster of Tobacco. A certain Person swallowed a large Morsel of Calf's Lights, which stopt in the Middle of the Gullet, and exactly filled up the Passage. A Surgeon unsuccessfully attempted various Methods to extract it; but another seeing how unavailable all of them were; and the Patient's Visage becoming black and swelled; his Eyes ready to start, as it were, out of his Head; and falling into frequent Swoonings, attended with Convulsions too, he caused a Glyster of an Ounce of Tobacco boiled to be thrown up; the Consequence of which was a violent Vomiting, which threw up the Substance that was so very near killing him.
