foresaid humour according, and the inner heate euen working with the heate of the Sunne, in the aire, neither humour, and putteth out the watry humour into leaues, and the fattie humour into fruit. Also Aristotle saieth, that men in olde time meaned, that fruite and leaues are all in one kind, and they said that leaues be not, but by cause of fruite, and they be not diuers in maner, but by more di∣gestion or lesse of watrye and rawe hu∣mour: for watry humour and thinne is soone drawen by heate of the Sunne, and turneth into leaues: and the humour that is more fattie and digest tourneth into matter of fruite.
Also Aristotle saith, that though some trées be full of prickes, that commeth not of the intention of kinde, that ge∣dereth the substaunce of the trée: but it hapneth of thinnesse of the trée, whereby ther colde humour, that is but little sod, and issuing out by ye thinnesse of ye trée, is gathered into a pricke or a thorne by heate of the Sunne, and is great by the stalke or stocke, and sharpe at the e••••s: for subtill humour, that is the humour materiall of thornes and prickes, passeth from the tree some and some, and stret∣cheth in length and in sharpnesse, and so doe all such trées, that be with parts sha∣pen in manner of a top. Also generally all trées be gréene without, and white within: for the matter of the inner parts draweth to white coulour, and the vtter parts draw to greene coulour. For the matter that is drawen inwarde, and is driuen outwarde into the barks, is somwhat digested & turned into gréene, for gréene is the middle colour betweene red, that commeth of the action and wor∣king of the perfect and complete heate: & betwéene white, that commeth of im∣perfect.
Also Aristotle saith, that trées be di∣uers in figure & shape: for some stretch vpward, and some downward, and some aside, and some holde the meane: & those that haue small and thinne humour in their pith, the which humour is moued and drawen vpward by heate, be shaped or haue the forme of light of fire, that moueth in common vertue of fire.
And such that haue in their pith thicke vertue of humour and watrye, growe downeward and be small: and so those parts moue downward by their owne heauinesse; and be great and lowe by the ground. In those that haue meane hu∣mour and are temperate betwéene thicke and thin, some moue vpward, & is cause of mouing vp of the trée, and some moue downward, & is cause of greatnesse ther∣of: and so as that humour is more or lesse digested in the roote and in the pith, the trée is more or lesse in figure & shape, for the first digestion is néedefull in the roote to the growing of the trée, and the second digestion is néedefull in the pith, for perfection, riping, dilatation, and con∣seruation. This double digestion, suffi∣ceth the perfection of trées and of herbs, and the third is found onely in beastes, as Aristotle saith, and as Albumasar expoundeth.
Also trées be diuers in boughes, & in leaues, as the humour is more or lesse: and as strength of heat is more or lesse: for if the heate be strong with much hu∣mour, then spring manye boughes and leaues, and againward: and if the hu∣mour be small and thin, and able to bée wasted and foredryed, than the boughes doe wither and the leaues fall, & the trée abideth all bare without any leaues: & the contrarye falleth in the contrarye cause.
Also Aristotle saith, that not alonely shornes and prickes in trées, be shapen in manner of topwise, but also the shape is found in fruit and in leaues: for if the wayes in a trée be first wide and large, and full thin in the beginning of the hu∣mour, and afterward be made narrowe by coldnesse and drinesse: then the fruit and leaues be great and large in the ne∣ther ende, and small and sharpe in the o∣ner ende, and that is for drawing of the more light part of the humour to the o∣uer ende by strength of heate, and put∣ting of the heauie humour towarde the nether ende. But full ofte it happeneth, that fruite and leaues be sharpe in the endes, and shapen in manner of a toppe, when by the vertue of heats and by the thin and small humour the ouer part is
