Of a Sjmptomatick Fever. 



IH AV E explain'd, under the Sixth Chapter, f^J^^^?^' 

 v.hat I mean by a Symptomatick Fever, I'/z. pgyej. 

 that it is a Fever proceeding from Accidents, rather what. * 

 than any noxious Quality in the Blood itfelf : As 

 for Inftance, the Gout in Human Bodies caufes a 

 Symptomatick Fever, fo does the iirll Milk in Wo- 

 men's Breafts ; and in Brute Creatures, as I have 

 faid, too indent Exercije in hot Weather ^ or in Cold, 

 when not duly managed afterwards. 



Secondly, this Fever may be occaiioned by turning 

 a Florfe to Grafs in very hot Weather ; efpecially 

 if the Inclofure be fmall, where there is but little 

 Air, and where there is not any convenient Shade to 

 cover him from the fcorching Heat of the Sun. 



Mr. Gibfon, in his Book of Farriery, fays, that 

 *' this Fever (I m.ean what he calls Simple, and 

 *' what I term Symptomatick) may be caafed by 

 *' Bleeding a Horfe in the Heat of the Sun, in a 

 " hot Seafon, without houfmg ; and that becaufe 

 ** during the Operation the Blood is put into a 

 *' greater Motion than ordinary, and that this new 

 " Motion is kept up and increafed by the additional 

 " Heat of the Weather. " And he father fays, 

 " that this Do6lrine may be illuflrated by the com- 

 * * inon Effeds of Fire under a Pot or Kettle, where 

 " the Heat of the V/'ater increafes m^ore in the fame 

 " Spaces of Time, according to the Degrees of its 

 *' Motion, tho' the Fire be not increas'd. " Now, 

 for my Part, I frankly confefs, I don't rightly ap- 

 prehend Mr. Gibfon's Meaning, unleis it is, that the 

 Water heats more in the fame given Tim.e when 

 near boiling, than it did a while before ; but at befl: 

 this is only a very lame and unfatisfaftory Experi- 

 ment.
