rally at a greater height in children than in a dults; becomes more confiderable in winter than in fummer; and those patients who go foon into the open air, are more feverely attacked with it than those who keep longer confined.

This stage of the diforder is evidently attended with more danger, that is, more patients die at this period than do in the more early or febrile ftate of the disease.

Thefe are the ufual and ordinary symptoms of this disorder; a variety of others, however, sometimes occur, which may be reckoned of an anomalous nature, viz. haemorrbagies at the nose, cough, bloody faliva, fneezing, fwellings of the parotids and glands of the neck; and now and then occur abfceffes in the fauces, ears, breast, and other parts.

Our author, after giving the opinions of different writers on this diforder, proceeds to treat of the diagnofis, caufes and feat of the disease, and afterwards goes on to the method of cure.

In the treatment of the milder fpecies of scarlet-fever, little farther is neceffary, we are told, than a due attention to diet, and the other nonnaturals; but, whenever the disease puts on a

more

more inveterate form, as confiderable danger is then to be apprehended, other circumstances muft also be attended to.

Blood-letting, especially in the feet, is here freely recommended by our author. Objections, he observes, have been made to this practice in every disorder of the eruptive kind, upon the supposition of its frequently occafioning a retroceffion of the eruption. But, from long experience on this point, not only in the disease in question, but in the small-pox, we are affured of its being commonly attended with the very best effects. And, in the fcarlet-fever efpecially, if blood-letting be not had recourse to when the inflammatory symptoms run high, the patient, we are told, will run a confiderable risk of being carried off, either by immediate fuffocation, or by a subsequent mortification, So neceffary a part of the cure is blood-letting confidered by our author, that he recommends it even where the pulfe happens to be weak, quick, and unequal; and he remarks, that when, in such cases, it is had recourse to, it always renders the pulse more firm, soft, and equal.

After blood-letting has been had recourfe to, blifters to the neck and inferior extremities are

When the inflammatory ftate of the complaint is pretty much over, Peruvian bark is then recommended as a principal remedy; and as, in this diforder, it cannot be taken in fufficient quantities, in the ordinary way, from the fwelling of the fauces which commonly prevails, we are defired to have recourfe to frequent dozes of the extract, and to inject, by the anus, glyfters composed of the decoction of bark.

All the warm fudorific and cordial remedies

frequently had recourse to in this disorder, are much condemned; for, inftead of producing any defirable effects, they almost always, we are told, tend to aggravate the different symptoms, as they juft as readily occafion a determination, our author thinks, to the brain, and other internal vifcera, as to the furface of the body.

In the malignant fpecies of the fcarlet-fever, restlessness, we are told, is frequently a troublefome fymptom. In fuch cafes, gentle paregorics are recommended.

For the prevention and cure of that leucophlegmatic swelling, which fo frequently fucceeds

the fcarlet-fever, as the urine is commonly much diminished in quantity, infufions of juniper-berries, and other diuretics, are chiefly recommended.

In obftinate cafes of this kind, mercury, together with aurum fulminans, are mentioned as very effectual remedies, and are recommended in the following forms:

B. Rhei electi

Spirit. falis coagulati utriufque drachmas duas
Mercurii dulcis

Auri fulminantis

Extract. Scillae, fingulorum femidrachmam

M. f. pill. cum Rob. Juniperi pondere unius alteriufve grani

Of thefe pills, one or two are to be given every two or three hours, according to the age and strength of the patient; and, if they do not procure three or four stools a day, the done should either be increased, or some other species of laxative conjoined with the pills, fo as to produce that effect, and to prevent falivation, which otherwife might probably take place.

Aurum fulminans is here recommended in every cafe where a fure and fafe laxative is wanted, as it does not operate in that violent manner that many practitioners have afferted,

In this stage of the diforder, patients frequently fall into a torpid lethargic ftate; for which, bleeding with leeches behind the ear is recom mended, together with blifters to the neck and head.

As an appendix to this differtation, seventeen cases of scarlatina are related at full length; but, to transcribe any of them here, would extend this article farther than the nature of our work admits of.
