Chap. VII. Of a fmple continued Fever 3 1 . 



and Midriff-, and moreover in the Lungs themfelves, is the 

 Caufe of ihe heaving of the Flanks, whereby the Lungs 

 arc deprels'd too clofe on all Sides, upon which the Pafia- 

 ges of Refpiration become obftruded ; whereas in other 

 Cafes, the lame Signs may be exhibited from the want of 

 Spirits, by which means the Adlion of the Mufcles, which 

 elevate and deprefs the Thorax^ mufl be hinder'd ; but 

 this may be ealily dillinguifh'd, by an Infenlibility and 

 Lidlefnefs to Modon ; as may alio an Inflammation of 

 the Lungs or Pleura^ from the manifeil Signs of infup- 

 portable Pain, as Oiall be obferv'd in its proper Place. 



Fifthly^ Albeit Pain is a Sign common to fcvcral kinds 



of Fevers, yet it is more violent in this than in any other^ 



as the Pain proceeds from an over-plenitude and fulnefs of 



the Vellels ; and therefore when we obferve a Horfe apt 



to fhrink or ftrike, as often as any one comes near him, but 



efpecially upon offering to touch his Back, we may fuppofe 



:this to be cccafion'd from Pain in the Back and Loins, 



'arifing from an over-diitention of the Aorta^ or great 



Artery, that Vefiel lying open and unguarded, and hav- 



: ing no (lore of Mufcles to inviron and fupport it. The 



i Farriers oftentimes, in this fort ofFever, when they obferve 



!a Horfe unwilling to have any one lay Hands on hi^^hind 



'Parts, believe it to be the Sign of a fway*d Back, and make 



li^eir Applications accordingly. But we fhall have an 



< )pportunity of putting them right in this Particular here- 



a!"ter. 



Laftly^ The conftant Watchfulnefs and Reftlefnefs 

 v/iuch is fo obfervable, and feems, in a great Meafure, pe- 

 -■iar to a limple Fever, is alfo the Refult of a very great 

 \ .Vi'efaclion and Thinnefs of the Blood ; the animal Spirits 

 ■:i therefore be the more eafily feparated from fo loofe a 

 . exture, and the Veilels, being at the fame Time full, muft 

 t.ierefore prefs upon the Nerves, cauHng a continual flux 

 id reflux of the faid Spirits, from v.hence muft undoubt- 

 - '.y proceed V/atchfulnefs and Reftlefnefs. But in Fe« 

 I vers of another Kind, thefe Signs feidom or never go toge- 

 Ithcr; but if a Horfe be v/atchful, he is, perhaps, at the 

 fame time fluggifh and heavy ; or if a Horfe be reftlefs, 

 and fometimes in a m.oving Pofture, he does not continue 

 long fo, but becomes dull and unadive by Intervals, efpe- 

 cially if the Blood is of uneqi^al Fluidity ; for in fuch a 

 Cafe, when the vifcid and tenacious Parts are got into the 

 nail hair-like Vefleis of the Brain, there mud at that time
