For Iiere we not only find the Effedl of fuch DifTo- 

 lution in the Secretions, but likewiie we are ac- 

 quainted with the Caufe of it, to wit, the Force of 

 the Air in Refpiration breaking the Globules of the 

 Blood, which Force i.s demonftrable to exceed the 

 PrefTure of a Hundred Pounds Weight upon the Sur- 

 face of the Lungs in a human Body, and much more 

 in a Horfe, whofe Lungs are far bigger than ours. 

 Nor is it evideni only from the Caufes and EfFe£ts, 

 that the Blood is here moft diffolved, butlikewife- 

 from the. very Methods wliich Nature takes to pre- 

 vent the Effefts of this DifTolution in fome particu- 

 lar Places at a little Diftance from the Heart : For, 

 rhe Bile or Gall, and Seed of Animals being thick 

 Humours, compcfed of Particles which combine but 

 ilowly together, and it being requifite they fhould 

 be feparated where the Liver and Teflicles are placed. 

 Nature lias made Ufe of particular Contrivances to 

 give the Particles, which were to form thefe Hu- 

 mours, mere Time to combine than they would 

 have had otherwife, being fo ne?.r to the Heart. 



■ For the Formation of the Gall, {he has contrived The For- 

 the Fena Port^, and the Spleen ; thro' the firft the ';?^ft",?^ 

 Blood moves near two hundred Times fiower (and ^ - ** * 

 thro' the laf: altogether as much,) than otherwife it 

 would have done ; and that the Particles which 

 form the Seed m.ight have Time to combine, the 

 Orifices of the Spermatick Arteries are contraded, 

 and they likewife arife from the Vena Cava a little 

 below the Enmlgents, at a great Diflance from the 

 Tefticles, contrary to the common Courfe of Na- 

 ture ; by which Means the Blood is One hundred 

 and fifty Times flower or longer in going to the 

 Teflicles or Stones, than otherwife it would have 

 been. 



At the greateft DiHance from the Heart, the vif-The vif- 

 cous Liquor of the Joints is fecern'd^ as alfo fomecous Li- 

 other Liquors, which do not require any Combina- ^^P"* O'^'^^s 

 tions ; as the Ljmpha or watry Humour, which may -J^^^^^' ^^, 

 be feparated any where. /\nd all thefe different parated,
