       thofe kinds of crftfaceous creatures, efpecially about their bellies,
       feem'd of three kinds ; the head F feem'd cover'd with a kind of fealy
       ibell, the thorax with two fmooth fhells, or Rings, G G, and the belly
       with eight knobb'd ones. I could not certainly find whether it had
       there laft fhells any wings, but I fufFed the contrary ; for I have
not found
       any wing'd Infe&t with eight leggs, two of thofe leggs being always
       verted into wings, and, for the moff part, thofe that have but fix,
         This creature, though I could never meet with more then one of
       them, and fo could not make fo many examinations of it as otherwife
       would,ldid notwithftanding,by reafon of the great curiofity that appear'd
       to me in its fbapedelineate it, to {hew thatin all likelihood, Nature
       crouded together into this very minute Infe&, as many, and as
       contrivances, as into the body of a very large Crab, which exceeds
it in
       bulk,perhaps,fome Millions of times ; for as to all the apparent partstthere
       is a greater rather then a lefs multiplicity of partseach legg has
as many
       parts, and as many joints as a Crabs, naykand as many hairs or brifles;
       the like may be in all the other vifible parts ; and 'tis very likely~that
       internal curiosities are not lefs excellent: It being a general rule
in Na-
       ture's proceedings, that where The begins to difplay any excellency,
       the fubje&t be further fearch'd into, it will manifeft, that there
is not lefs
       curiofity in thofe parts which our fingle eye cannot reach, then in
       which are more obvious.
           Obferv. L I I. Of the fmall Silver-colour'd Book-worm.
        A S among greater Animals there are many that are fcaled, both for
        FA  ornament and defence, fo are there not wanting fuch alfo among
        lefler bodies of Infeffs, whereof this little creature gives us an
        It is a fmall white Silver-fhining Worm or Moth,which I found much
        verfant among Books and Papers, and is fuppos'd to be that which
        rodes and eats holes through the leaves and covers; it appears to
        naked eye, afimall gliftering Pearl-colour'd Moth,which upon the
        ing of Books and Papers in the Summer, is often obferv'd very nimbly
        fcud, and pack away to fome lurking cranney, where it may the better
        proteCt it felf from any appearing dangers. Its head appears bigg
        blunt, and its body tapers from it towads the tail, fmaller and Imaller,be-
        ing fhap'd almoft like a Carret.
          This the AMicrofcopicalappearance will more plainly manifeft,which
       hibits,inthe third Figure of the 33.schemes, a conical body, divided
       fourteen feveral partitions,being the appearance of fo many feveral
       or fields that cover the whole body, every of thefe fhells are again
       ver'd or tiled over with a multitude of thin transparent fcales, which,
       from the multiplicity of their reflefting furfacesmake the whole Animal
       appear of a perfect Pearl-colour.
