They answered, that each of them was a perfect eye, by reason they perceived that each was covered with a transparent cornea, containing a liquor within them, which resembled the watery or glassy humour of the eye. To which the Empress replied, that they might be glassy pearls, and yet not eyes; and that perhaps their microscopes did not truly inform them. But they smilingly answered her Majesty, that she did not know the virtue of those microscopes; for they never delude, but rectify and inform the senses; nay, the world, said they, would be but blind without them, as it has been in former ages before those microscopes were invented.

After this, they took a charcoal, and viewing it with one of their best microscopes, discovered in it an infinite multitude of pores, some bigger, some less; so close and thick, that they left but very little space betwixt them to be filled with a solid body; and to give her Imperial Majesty a better assurance thereof, they counted in a line of them an inch long, no less than 2,700 pores; from which observation they drew this following conclusion, to wit, that this multitude of pores was the cause of the blackness of the coal; for, said they, a body that has so many pores, from each of which no light is reflected, must necessarily look black, since black is nothing else but a privation of light, or a want of reflection. But the Empress replied, that if all colours were made by reflection of light, and that black was as much a colour as any other colour; then certainly they contradicted themselves in saying that black was made by want of reflection.

However, not to interrupt your microscopical inspections, said she, let us see how vegetables appear through your glasses; whereupon they took a nettle, and by the virtue of the microscope, discovered that underneath the points of the nettle there were certain little bags or bladders, containing a poisonous liquor, and when the points had made way into the interior parts of the skin, they like syringe-pipes served to convey that same liquor into them. To which observation the Empress replied, that if there were such poison in nettles, then certainly in eating of them, they would hurt us inwardly, as much as they do outwardly? But they answered, that it belonged to physicians more than to experimental philosophers, to give reasons hereof; for they only made microscopical inspections, and related the figures of the natural parts of creatures according to the representation of their glasses.

Lastly, they showed the Empress a flea, and a louse; which creatures through the microscope appeared so terrible to her sight, that they had almost put her into a swoon; the description of all their parts would be very tedious to relate, and therefore I’ll forbear it at this present. The Empress, after the view of those strangely-shaped creatures, pitied much those that are molested with them, especially poor beggars, which although they have nothing to live on themselves, are yet necessitated to maintain and feed of their own flesh and blood, a company of such terrible creatures called lice; who, instead of thanks, do reward them with pains, and torment them for giving them nourishment and food. But after the Empress had seen the shapes of these monstrous creatures, she desired to know, whether their microscopes could hinder their biting, or at least show some means how to avoid them? To which they answered, that such arts were mechanical and below the noble study of microscopical observations. Then the Empress asked them, whether they had not such sorts of glasses that could enlarge and magnify the shapes of great bodies as well as they had done of little ones? Whereupon they took one of their best and largest microscopes, and endeavoured to view a whale through it; but alas!
