knows that the heart is a Muscle endued with spiral Fibres fitted for Contraction that it hath two Ventricles for reception of the Blood in its dilatation that it hath valvules of two kinds to hinder the return of the Blood from the Arteries to the heart again that the Arteries have transverse Fibres by which they contract themselves and press forward the Blood 'T is certain that every part that is contracted has an innate faculty to perform that Action which is done by the influx of the animal Spirits into the Fibres of whatever kind they are On the contrary it is as certain that all parts that are dilated can never dilate themselves but when dilated they do ever suffer Violence from the humours or what ever else they contain 'T is true the Pharinx and the Cartilagines Aritenoides are dilated not by any thing they contain but by reason of the Muscles joyned to the outside of either so is the mouth dilated by the Muscles of the nether jaws 'T is also certain that the Ventricles of the heart every one of which containeth at least a Dragme of Blood when dilated are of the same substance with the inner Coats of the Arteries and Veins and are sensible of irritation that in the dilatation of the Heart the Quantity the Heat the Weight and the Distention through the effervescence of the Blood doe irritat it that this irritation makes the heart contract it self without respect to a final Cause as this Dreamer Fancies to himself that at the same instant of the hearts contraction the Blood is thrust out with Violence into the Aorta and by Continuity into all the Arteries of the Body by which they are dilated while the heart is contracted and that the Pulse that stricks our Fingers is nothing else but the Dilatation of the Arteries occasioned by the contraction of the Heart at the same instant For Dolphingtoun then to allow that in a Feaver the pulses are more frequent and yet to say that the motion of the Blood is more slow this is the greatest Nonsense one can be capable of For at every pulse I suppose but adragme of the Blood to bethrust into the Arteries by the contraction of the Heart this Blood can not return because of the Valvules forward it must go otherwayes the Arteries should burst asunder and consequently the more frequent the pulses are the motion of the Blood must be the swifter It has been alwayes a received Opinion that heat in a Feaver is the effect of the rapide motion of the Blood Neither does Dolphingtoun's or Bontilo's objection destroy this position for though the Blood Stagnat in an Inflammation where the member is otherwayes affected with more than ordinary heat yet there being such a quantity of extravased Blood which does not coagulat but is still fluid because of the few Spirits it retains And the capillary Arteries being distended with Blood which is the cause of the pulse where there was none 〈…〉 't is no wonder if that part be affected ●●●h more than ordinary heat since it c●●●●ains more than ordinary Blood for where there is much Blood there Is much heat I shall only send Dolphingtoun home to Churn his Butter to prove that there is heat in Fluids after a few hours motion of the Churn he will find the heat he denies I use this Familiar instance because he never found the heat that is raised when the spirit of Vitriol is poured upon the Oyle of Tartar since he never saw the experiment In immoderate motion of the Body there Is a frequent motion of the Blood occasioned by the frequent motion of the Muscles by this motion the heat is raised before there be any Consumption or Waste In this motion likewayes the Blood is rarified by the heat the pores are opened and sweat does for the most part follow But because of the separation of the serous part the Blood at length becomes more thick which does not fall out till the pulse settle again But this Fool mistakes alwayes the cause for the Effect His Diaphanous Blood and his reflected and refracted rayes of heat in the Body are nonsense not worth the refuting After all this ma●●●● 〈◊〉 not given us the definition of a Feaver 〈◊〉 which we may know its Nature and E●●●●ce and its difference from other Diseases But being weary to answer a Fool in his Folly I leave this Misanthrope to his own evil Genius with this assurance that whatever further he writes shall never be thought worthy of my Consideration FINIS
