Some verity it may also have in it self, as truly declaring the corruptive constitution in the present sap and nutrimental juice of the Tree; and may consequently discover the disposition of that year, according to the plenty or kinds of these productions. For if the putrifying juices of bodies bring forth plenty of Flies and Maggots, they give forth testimony of common corruption, and declare that the Elements are full of the seeds of putrifaction, as the great number of Caterpillars, Gnats, and ordinary Insects do also declare. If they run into Spiders, they give signs of higher putrifaction, as plenty of Vipers and Scorpions are confessed to do; the putrifying Materials producing Animals of higher mischiefs, according to the advance and higher strain of corruption. 3. Whether all Plants have seed, were more easily determinable, if we could conclude concerning Harts-tongue, Fern, the Caterpillaries, Lunaria, and some others. But whether those little dusty particles, upon the lower side of the leaves, be seeds and seminal parts; or rather, as it is commonly conceived, excremental separations, we have not as yet been able to determine by any germination or univocal production from them when they have been sowed on purpose: but having set the roots of Harts tongue in a garden, a year or two after there came up three or four of the same Plants, about two yards distance from the first. Thus much we observe, that they seem to renew yearly, and come not fully out till the Plant be in his vigour: and by the help of Magnifying Glasses we find these dusty Atoms to be round at first, and fully representing seeds, out of which at last proceed little Mites almost invisible; so that such as are old stand open, as being emptied of some bodies formerly included; which though discernable in Harts-tongue, is more notoriously discoverable in some differencies of Brake or Fern. But exquisite Microscopes and Magnifying Glasses have at last cleared this doubt, whereby also long ago the noble _Fredericus Cæsius_ beheld the dusts of Polypody as bigg as Pepper corns; and as _Johannes Faber_ testifieth, made draughts on Paper of such kind of seeds, as bigg as his Glasses represented them: and set down such Plants under the Classis of _Herbæ Tergifætæ_, as may be observed in his notable Botanical Tables.
