Now, as this furnishes us with one odd History more, very agreeable to what
I before hinted, so I doubt not, but were men diligent observers, they
might meet with multitudes of the same kind, both in the Earth and in the
Water, and in the Air, on Trees, Plants, and other Vegetables, all places
and things being, as it were, _animarum plena_. And I have often, with
wonder and pleasure, in the Spring and Summer time, look’d close to, and
diligently on, common Garden mould, and in a very small parcel of it, found
such multitudes and diversities of little _reptiles_, some in husks, others
onely creepers, many wing’d, and ready for the Air; divers husks or
habitations left behind empty. Now, if the Earth of our cold Climate be so
fertile of animate bodies, what may we think of the fat Earth of hotter
Climates? Certainly, the Sun may there, by its activity, cause as great a
parcel of Earth to fly on wings in the Air, as it does of Water in steams
and vapours. And what swarms must we suppose to be sent out of those
plentifull inundations of water which are poured down by the sluces of Rain
in such vast quantities? So that we need not much wonder at those
innumerable clouds of Locusts with which _Africa_, and other hot countries
are so pestred, since in those places are found all the convenient causes
of their production, namely, genitors, or Parents, concurrent receptacles
or matrixes, and a sufficient degree of natural heat and moisture.
I was going to annex a little draught of the Figure of those Nuts sent out
of _Devonshire_, but chancing to examine Mr. _Parkinson_’s Herbal for
something else, and particularly about Galls and Oak-apples, I found among
no less then 24. several kinds of excrescencies of the Oak, which I doubt
not, but upon examination, will be all found to be the _matrixes_ of so
many several kinds of Insects; I having observ’d many of them my self to be
so, among 24. several kinds, I say, I found one described and Figur’d
directly like that which I had by me, the _Scheme_ is there to be seen, the
description, because but short, I have here adjoin’d _Theatri Botanici
trib. 16. Chap. 2. There groweth at the roots of old Oaks in the
Spring-time, and sometimes also in the very heat of Summer, a peculiar kind
of Mushrom or Excrescence, call’d _Uva Quercina_, swelling out of the
Earth, many growing one close unto another, of the fashion of a Grape, and
therefore took the name, the _Oak-Grape_, and is of a Purplish colour on
the outside, and white within like Milk, and in the end of Summer becometh
hard and woody._ Whether this be the very same kind, I cannot affirm, but
both the Picture and Description come very neer to that I have, but that he
seems not to take notice of the hollowness or Worm, for which ’tis most
observable. And therefore ’tis very likely, if men did but take notice,
they might find very many differing Species of these Nuts, _Ovaries_, or
_Matrixes_, and all of them to have much the same designation and office.
