 of the Feaver an inclination to vomit, but no vomit was given; and that those symptoms, which commonly are imputed to a malignity, do, for the most part, proceed from the Relaxation of the tone of the Bloud, caused by Medicines too refrigerating, or by the unseasonable use of Glisters in the declination of the disease. As to the Latter, he observes, that one of the chief causes, rendring the Cure of Feavers so uncertain and unsuccessful, is, that Practitioners do accommodate their observations, they take from the successful cure of some Feavers in one season of the year, or in some one year, to that of all Feavers in any season, or in any year whatsoever. And here he observes, first, how vigorous the blood is in the Spring, and how dispirited in Autumn; and thence regulates the letting of bloud, and Vomiting, and the giving of Glisters. Next, how difficult it is, to assign the cause of the difference between the Feavers of Several years; and to prognosticate of the salubrity or insalubrity of the following part of the year; where yet he insinuates, that, when Insects do swarm extraordinarily, and when Feavers and Agues (especially Quartans) appear very early, as about Midsummer, then Autumn commonly proves very sickly. Lastly, what method and Cautious are to be used in the Cure of Epidemical Feavers.

In the Second Section, he treats of the Symptoms, accompanying Continued Feavers; as Phrensies, Pleurisies, Coughs, Hicoughs, Fluxes,&c. Shewing, both whence they are caused, and how they are to be cured: Where having inserted a considerable Paragraph, touching a certain Symptomatical Feaver in the Spring, to be cured like Plurisies; he mentions among many Observables, this, as a chief one, that Laudanum, or any other Narcotick given against the Phrensy, in the beginning, progress, or height of a Feaver, does rather hurt, than good, but in the declination thereof, is used with good success. To all which he subjoins a particular Rh
