window, one thing of which was a large Tree, whofe trunk and top } 
. could plainly difcover, as Icould alfo the parts of my window, and my. 
“” hand and fingers, if I held it between the Window and the Obje@; a 
{mall cravat of nineteen of which, as they appear'd inthe bigger Mag- 
“nifying-glais to reflect the Image of the two windows of my Chamber, 
~ are delineated in the third Figure of the 23. Scheme. WG 
Fourthly, that thefe rows were fo difpos'd, that there was no quarter 
vifible from his head that there was not fome of thefe Hemijpheres directed 
_againft ; fothat a Fly may be sa 8 faid to have am eye every way, and to 
be really circumfpe@. And it was further obfervable, that that way where 
the trunk of his body did hinder his profpecét backward, thefe protube- 
vances were elevated, as it were, above the plain of his fhouldersand 
back, fo that he was able to fee backwards alfo over his back. 
__«. Fifthly, in living Flies, [have obferv'd, that when any {mall mote or 
duft,which flies up and down the air, chances to light upon any part of 
thefe knobs, asit is fure to tick firmly to it and not fall, though throug}, 
the Aficrofcope it appears likea large {tone or ftick (which one would ad- 
mire,efpecially fince it is no ways probable that there‘is any wet or ea? 
nous matter upon thefe Hemi/pheres,but I hope I fhall render the reafon in 
another place) fothe Fly prefently makes ule of his two fore-feet in ftead 
of ey tas with which, as with two Brooms or Brufhes, they being 
all beftuck with Brifles, he often fweeps or brufhes off what ever hinders 
the profpect of any of his Hemifpheres, and then, to free his | from 
that dirt,he rubs them one again{ft another,the pointed Brifles or Tenters 
of which looking both one way, the rubbing of them to and fro one 
againft another, does cleanfe them in the fame manner as I have obferv'd 
thofe that Card Wool, to cleanfe their Cards, by placing their Cards, fo 
asthe teeth of both look the fame way,and then rubbing them one againft 
another. In the very fame manner do they brufh and cleanfe their bodies 
and wings, as! fhall by and by thew; other creatures have other contti- 
vances for the cleanfing and cleering their eyes. 
Sixthly, that the number of the Pearls or Hemifpheres in the clufters 
of this Fly, wasneer 14000. which I judged by numbering certain rows 
_ of them feveral ways, and cafting up the whole content , scones 
each clufter to contain about feven thoufand Pearls, three thou fan 
of which were ofa cize, and confequently the rows not fo thick, and 
the foure thoufand I accounted to be the number of the fmaller Pearls 
next the feet and probofcis. Other Animals I obferv’d to have yeta 
greater number, as the Dragon-Fly or Adderbolt > And others to havea 
a Jefs company, as an Ant, &c. and feveral other {mall Flies and 
_ Seventhly.that the order of thefe eies or Hemifpheres was altogether cuti- 
ous and admirable,they being plac’d inall kind of Flies,and aerza/ animals, 
in a moft curious and regular ordination of triangular rows, in whichor- 
der they are rang’d the neereft together that poflibly they can, and con- 
fequently leave the leaft pits or trenches between them. But in Shrimps, 
| Granfihes, Lobfiers, and fuch kinds of Cruflaceous water Animale;thave
