The pleurify is known by a violent pricking pain in the fide, a frequent hard pulse, a difficult painful breathing, a very troublesome cough, and sometimes bloody spittle; it is either moist or dry. In the peripneumony, the pain is not so acute, but is more tensive, blunt and pressing; the difficulty of breathing and anxiety is greater, the pulse is soft and quick, the expectoration more troublesome, and the spittle is of various colours.

In the cure, you must bleed freely the three first: days of the disease, unless the spitting begins in that time, and the bleeding must be omitted or so moderated, that the breast may be relieved without checking the expectoration : after the fourth day bleeding is unsafe, but blisters will shorten the cure, and prevent the loss of a great deal of blood; for a simple pleurisy, or one attended with, little inflammation of the lungs, may be cured with little bleeding, by a blister of the size of the hand and fingers laid to the affected side, and is best applied imme-diately after the first bleeding. If the symptoms vanish upon this application, it will be safest to bleed again, unless a profuse sweat eases the pain, and then all other remedies will be rendered unnecessary; but if the lungs are much inflamed, the blister and bleeding must be repeated, though the patient is pretty easy.

In A Peripneumony, blistering is most to be relied on after bleeding, first on the back, and then on both the fides; blistering on the extremities likewise tends to ease the breast and promote expectoration; bleeding must be cautiously used if at all, after the spitting appears.

In the first stage of either of these diseases, laxative clysters are proper, as also cool diaphoretics, such as eight grains of nitre made up into a bolus with conserve of hips; but purges and warm diaphoretics are hurtful. Whenever the patient begins to spit, diaphoretics must be omitted, or joined to things that promote expectoration, of which the chief is oxymel of squills; the dose is from two drams to half an ounce. In low-ness, after repeated bleedings, give the following pectoral bolus: "Take of sperma ceti fifteen grains, of gum ammoniac ten "grains, of salt of hartshorn seven grains, of syrup of sugar "enough to make a bolus." This is a powerful remedy to raise the pulse, and to promote expectoration when it flags : notwithstanding this discharge, if the lungs continue to labour, bleeding will be requisite, for it will be dangerous to suffer the lungs to be overpower'd by the omission of bleeding, as well as to hazard the suppression of the spitting by bleeding too freely; but blisters are always seasonable. In the course of expectoration, a vomit, with an ounce and a half of oxymel of squills, will be useful to discharge the load of viscid phlegm. Opiates are not to be given when the pulse is hard, the breathing difficult, or watchfulness continually occasioned by a fever: but when the fever is over and sleep is only prevented by a thin defluxion on the lungs, opiates will procure rest and promote the spitting. If the phlegm is tough and the patient costive, then squills may be properly joined; but if the body is open, and the head is affected with the opiate, salt of hartshorn is the best corrector.
