Sec. 51. In this, and in all other inflammatory Diseases, the Blood is in a very thick viscid State: and almost immediately on its being drawn, a white tough Skin, somewhat like Leather, is formed on its Top, which most People have seen, and which is called the _pleuritic Crust_. It is thought a promising Appearance, when at each Bleeding it seems less hard, and less thick, than it was at the preceding ones: and this is very generally true, if the Sick feels himself, at the same Time, sensibly better: but whoever shall attend _solely_ to the Appearance of the Blood, will find himself often deceived. It will happen, even in the most violent Inflammation of the Breast, that this Crust is not formed, which is supposed to be a very unpromising Sign. There are also, in this Respect, many odd Appearances, which arise from the smallest Circumstances; so that we must not regulate the Repetitions of our bleeding, solely by this Crust: and in general we must not be over credulous in supposing, that the Appearances in the Blood, received into the Bason, can enable us to determine, with Certainty, of its real State in the Body. [20] We should however, with the greater Circumspection (of how much the longer standing the Disease has been, and by how much the more difficult the viscous Humours are to be melted down and dislodged) attend to the Coction of the Matter of Expectoration; which Nature does not often easily effect, and which she effects the more imperfectly and slowly, the weaker he is. Her last Efforts have often been attended with such high Paroxysms, as have imposed even upon very competent Physicians, and have made them open a Vein a few Hours before the Patients' Death, from their Pulses being strong, hard and frequent. Excessive Weakness is the Sign, by which we may discover such unavailing Efforts to be the last. _E. L._ Sec. 52. When the sick Person is in the Condition described (Sec. 47) the Bleeding is not only unattended with Ease; but sometimes it is also pernicious, by the sudden Weakness to which it reduces him. Generally in such a Case all Medicines and Means are insignificant: and it is a very bad Sign in this Disease, when this Discharge is not attended with Ease and Benefit to the Sick; or when there are some Circumstances, which oblige us to be sparing of it. Sec. 53. The Patient's Legs should every Day, for one half Hour, be put into a Bath of warm Water, wrapping him up closely; that the Cold may not check that Perspiration, which the Bath promotes. Sec. 54. Every two Hours he should take two Spoonfuls of the Mixture No. 8, which promotes all the Discharges, and chiefly that of Expectoration.
