Now forasmuch as there is nothing makes a Separation of the Blood more commonly than the want of usual Transpiration, so nothing more conduceth to the Preservation of Health, than that the Pores of the Body should continually let out the hot Streams and Vapours that arise from the Ebullition of the Blood; but when after taking Cold the Skin and Habit of the Body are on a sudden stopped up, that the sulphureous and waterish Excrements of the Blood cannot pass through the Pores, they are again resorbed into the Mass of Blood, from whence proceeds a feverish Disposition; unless they are carried off by Stool, or precipitated by the Kidneys, are sometimes translated to the Glandulous Parts of the _Lungs_, where by Degrees contracting more and more Heat and Sharpness they inflame and exulcerate these tender Parts. Nevertheless tho’ a _Consumption_ of the _Lungs_ is sometimes thus caused by taking Cold, yet this comes to pass but seldom, unless in such Bodies whose Mass of Blood being rendered Cachectic, thro’ frequent Influxes of dispirited Chyle, is pre-disposed to receive, and unable to free it self from this New Influx of Catarrhous Rheum: For suppose Two Persons in like manner deprived of the Benefit of usual Transpiration, by some great Cold, which tho’ troublesome in the beginning, because of a violent and continual Distillation of Extravasated _Serum_ upon the Glandulous Coat of the Wind-pipe, and other adjacent Glands, yet in the One of these it survives not the accidental feverish Disposition of the Blood, occasioned by the Stoppage of the Pores: For as soon as the Ferment ceaseth, the separated Humours, partly for want of a new Influx of _Serum_, and partly by the natural Heat of these Parts, are concocted into a thick sort of Phlegm, and coughed up; after the Expectoration of which separated _Serum_ the glandulous Parts presently recover their natural Tone, without any Remains of a Tumour, Cough, Shortness of Breath, or other Inconvenience; but in the other this feverish Ferment, occasioned by taking Cold, is not transitory, but so habitually fixed by means of some previous Indisposition, as to encrease the Effervescence and Colliquation of the Blood and Spirits; from whence all the Glands which are seated in the upper part of the _Larynx_, as also the glandulous Coat of the Wind-pipe it self are overflown with a Deluge of hot distempered Humours, the Substance of the _Lungs_ distended with hard Tumours, the Branches of the Wind-pipe comprest, and the Wind-pipe it self from these Swellings irritated to Cough, by a continual tickling, which promotes a frequent spewing out of hot sharp Humours all along the _Aspera Arteria_, till at length these Tubercles growing very large, begin to inflame and suppurate; immediately upon the breaking or opening of those Apostemes, sometimes such a Flood of corrupted Matter is poured out of their Baggs or Cavities, into the Branches of the _Trachea_, as compleatly suffocates and choaks the Patient; but at
