is but a fine pailage, or ftraining of the Juice of the Tree, throughthe |

Ariftotle giveth the caufe vainly, Why the Feathers of Birds are of more | 
lively colours than the Hairs of Beafts; for no Beafthath any fine Azure, or 
Carnation, or Green Hair. He faith it is, becaufe Birds aremore inthe 
Beams of the Sun than Beafts, butithatis manifeftly untrue ; for Cattleare | 
morein the Sun than Birds, thatlive commonly inthe Woods, or infome | 
Covert. Thetrue caufe is,that the excrementitious moifture of living Crea- |

The Clarifying of Liquors by Adhefion, is an inward Percolation, and is | 
effeGed, when fome cleaving Body is mixed and agitated withthe Liquors ; 
whereby the groffer part of the Liquor fticks to that cleaving Body; and fo} 
the finer parts are freed from the groffer. So the Aporhecaries clarifie theit | 
Syrups by Whites of Eggs, beaten withthe Juices which they would clarifie; | 
which whites of Eggs, gather all the dregs and grofler parts of the Juice to} 
them; and after the Syrup being fet onthe fire, the whites of Eggsthem-} 
felves harden, and aretaken forth. So Ippocraf is clarified by mixing with | 
which they call Hippocrates Sleeve ; andthe cleaving Nature of the Milk,dray- {

the paflage they ftickuponthe Woollen-bag. __ 4 ee
