A term of life is set to every man, Which is but short, and pass it no one can.
_Generation_.] The last of these vegetal faculties is generation, which begets another by means of seed, like unto itself, to the perpetual preservation of the species. To this faculty they ascribe three subordinate operations:—the first to turn nourishment into seed, &c. _Life and Death concomitants of the Vegetal Faculties_.] Necessary concomitants or affections of this vegetal faculty are life and his privation, death. To the preservation of life the natural heat is most requisite, though siccity and humidity, and those first qualities, be not excluded. This heat is likewise in plants, as appears by their increasing, fructifying, &c., though not so easily perceived. In all bodies it must have radical [981]moisture to preserve it, that it be not consumed; to which preservation our clime, country, temperature, and the good or bad use of those six non-natural things avail much. For as this natural heat and moisture decays, so doth our life itself; and if not prevented before by some violent accident, or interrupted through our own default, is in the end dried up by old age, and extinguished by death for want of matter, as a lamp for defect of oil to maintain it.
