An Heart which drives the Torrent through its Veins:
Muscles to move its Limbs aright: a Brain,
And Nerves, dispos'd for Pleasure, and for Pain:
Eyes to distinguish; Sense, whereby to know,
What's good, or bad, is, or is not, its Foe.
They too are pain'd with Love:—address the Fair,
And with their Rivals wage destructive War.
Delight in Blood, and solitary stray:
Others together herd, by Nature tame,
Nor Life destroy to feed their vital Flame.

Compass, they only related half the Number that they believed they had seen.
Now, from the Greatness of the Numbers mentioned, it is inferred, that in a full Drop of Water, there will be 8,280,000 of these Animalcula, which if their Smallness comes to be compared, a Grain of Sand, broken into 8,000,000 Parts, would exceed the Smallness of one of these Infects,
These Observations of Mr. Lewenhoeck's, were not only confirm'd by the famous Mr. Hook, but were likewise improved by him: He tells us, that after he had discovered vast Multitudes of those Animalcula, describ'd by Mr. Lewenhoeck, he made ufe of other Lights and Glasses, and magnify'd them to a very considerable Bigness; and that amongst them he discovered many other Sorts much smaller than those he first saw; some of which were so very minute that Millions of Millions of them might be contained in one Drop of Water."
