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! the shape of the whale was so big, that its circumference went beyond the magnifying quality of the glass; whether the error proceeded from the glass, or from a wrong position of the whale against the reflection of light, I cannot certainly tell. The Empress seeing the insufficiency of those magnifying-glasses, that they were not able to enlarge all sorts of objects, asked the Bear-men, whether they could not make glasses of a contrary nature to those they had showed her, to wit, such as instead of enlarging or magnifying the shape or figure of an object, could contract it beneath its natural proportion: Which, in obedience to her Majesty’s commands, they did; and viewing through one of the best of them, a huge and mighty whale appeared no bigger than a sprat; nay, through some no bigger than a vinegar-eel; and through their ordinary ones, an elephant seemed no bigger than a flea; a camel no bigger than a louse; and an ostrich no bigger than a mite. To relate all their optic observations through the several sorts of their glasses, would be a tedious work, and tire even the most patient reader, wherefore I’ll pass them by; only this was very remarkable and worthy to be taken notice of, that notwithstanding their great skill, industry and ingenuity in experimental philosophy, they could yet by no means contrive such glasses, by the help of which they could spy out a vacuum, with all its dimensions, nor immaterial substances, non-beings, and mixed-beings, or such as are between something and nothing; which they were very much troubled at, hoping that yet, in time, by long study and practice, they might perhaps attain to it.
The Bird- and Bear-men being dismissed, the Empress called both the Syrens or Fish-men, and the Worm-men, to deliver their observations which they had made, both within the seas, and the earth. First, she enquired of the Fish-men whence the saltness of the sea did proceed? To which they answered, that there was a volatile salt in those parts of the earth, which as a bosom contain the waters of the sea, which salt being imbibed by the sea, became fixed; and this imbibing motion was that they called the ebbing and flowing of the sea; for, said they, the rising and swelling of the water, is caused by those parts of the volatile salt as are not so easily imbibed, which striving to ascend above the water, bear it up with such a motion, as man, or some other animal creature, in a violent exercise uses to take breath.
