Such another was the _Specus Corycius_ in _Cilicia_, which upon the account of its stinking deadly Air, such as is thought to proceed from the Mouth of _Dragons_, which the Poets give to _Typhon_, was call’d _Cubile Typhonis_. This _Pompon. Mela_ (155) describes; and it is indeed as ancient as _Homer_ (156); for _Arima_, in which he places it, was, as _Eustathius_ says, a Mountain of _Cilicia_. Neither are such _Fumes_ as these infrequent Now-a-days; and though mostly taken notice of in Mines, Pits, and other Subterraneous Places, yet they are sometimes met with in the Surface of the Earth too, especially in Countries fruitful of Minerals, or pregnant with Imbowelled Fires; such are _Hungary_ and _Italy_, which latter (as _Seneca_ (157) observes) has always been more than any other remarkable for ’em. I shall therefore, having had the opportunity of making some Remarks upon One the most Famous of all in those Parts, give as good an account as I can of _That_, and its manner of Killing; which tho’ I dare not affirm to be universally applicable to any _Mephitis_ whatsoever, yet seems plainly to be the Case of most of ’em; and where it is not, this simple Mischief will only be found to be complicated with another; and then some extraordinary Symptoms or Appearances in the Animals kill’d, will easily make a Discovery of the Additional Venom and Malignity. This Celebrated _Mofeta_ taken notice of, (or at least some other hereabouts) even in the time of _Pliny_ (158), is about Two Miles distant from _Naples_, just by the _Lago d’ Agnano_, in the way to _Pozzoli_ or _Puteoli_, and is commonly call’d _la Grotta de Cani_, because the Experiment of its deadly Nature is frequently made upon _Dogs_; tho’ it be as certainly fatal to any other Animal, if it come within the reach of its Vapour; for _Charles the Eighth of_ France prov’d it so upon an _Ass_; and two _Slaves_ put into it by order of _D. Pietro di Toledo_, Viceroy of _Naples_, with their Heads held down to the Earth, were both kill’d (159).
