fourth of the whole-Kind ^ the firft three giving Motion and Agitation 

 to the Body, the fourth Generation and Increafe to fucceeding Ages. 



Now from, thefe principal Members, like Branches from a well-grown 

 Tree, do fpring other Members, which doth them Service : As from 

 the Brain fpring Sinews, whofe Office is feeling, from the Heart-Arte- 

 ries, whofe Office is Sprightlinefs and Livelihood ^ from the Liver- Veins, 

 whofe Office is Warmth and Strength ; and from the Stones the Seed- 

 Velfels, whofe Office is Procreation and Increafe. Now foralrnuchas 

 from thefe do likewife proceed a world of other Members, as Tendons y 

 Lig^memsy Lungs, Spleens, Guts, and fuch like-, all which, inafmuch as 

 the Knowledge of them doth more properly belong to the Office of the 

 Chirurgion, than to the Phyfician, f though moft necelTary to both; I am 

 here to advertife every ftudious Reader, that when he iliall have occafion 

 to meddle with any Member about a Horfe, that he turn to the fecond 

 Book of this Volumn, which treateth only of Chyrurgery, and there he 

 ihall not only find every Member and Lineament in a Horfe, but alio the 

 true Anatomy fo lively demonftrated, that there fliall be nothing want- 

 mg to the perfecting of his Underftanding. And thus much in this Place 

 of Members. 



C H A. p. VL Of Powers, and how a Horfe^s Body is governed by them. 



Powers which by fbme are called f^rtues, or principal Faculties, 

 and do govern and controul both the Body of Man and Beaft, and 

 have the fifth place in this Work, are in Number three, that is, the Power 

 Animal, the Power nral, and the Power Natural. T'he Power Animd, is a 

 \^irtue incident to the Brain, which through the Sinews coming like little 

 Conduit-pipes from the Brain, difh-ibuteth feeling and moving to all the 

 Parts of the Body. The Power Vital is a Virtue belonging to the Heart, 

 which doth give" Life and Spirit to all the Body,by means of the Arteries ^ 

 which proceeding from the Heart, which is the chief Fountain of natu- 

 ral Heat, carry in their little Channels over the whole Body, that Air 

 and fpiritual Blood which makes it full of Lightnefs and Alacrity. The 

 Power Natural is a Virtue belonging to the Liver, which gives Nouriih- 

 ment unto all the Bodv, and to every Part thereof, by means of the 

 V^eins, which do likewife proceed from the Liver, like greater Conduits, 

 carrying the Blood from the Liver, which is the Fountain of Blood, into 

 every pare of the Body. Befides, the Power Natural containeth four other 

 Virtues, that is, the Virtue AttraEilve, which draweth Food, Meat to 

 fuftain the Body •, the Virtue Retentive, by which it retaineth and keepeth 

 the Food received ; the Virtue Digeflive, whereby it conco£leth and di- 

 gefleth the fame *, and Laflly, the Virtue Expulfive, by which it expell- 

 eth Excrements and Superfluities. Thus thefe Powers or Virtues being 

 of no lefs validity than you perceive by this Difcourle, it is the Part and 



Duty
