none at all. Then the Empress asked them, in what part of their bodies that little blood did reside? They answered, in a small vein, which in lobsters went through the middle of their tails, but in crea-fishes was found in their backs: as for other sorts of fishes, some, said they, had only blood about their gills, and others in some other places of their bodies; but they had not as yet observed any whose veins did spread all over their bodies. The Empress wondering that there could be living animals without blood, to be better satisfied, desired the Worm-men to inform her, whether they had observed blood in all sorts of worms? They answered, that, as much as they could perceive, some had blood, and some not; a moth, said they, had no blood at all, and a louse had, but like a lobster, a little vein along her back: Also nits, snails, and maggots, as well as those that are generated out of cheese and fruits, as those that are produced out of flesh, had no blood: But, replied the Empress, if those mentioned creatures have no blood, how is it possible they can live? for it is commonly said, that the life of an animal consists in the blood, which is the seat of the animal spirits.

etc.

But, said she, have you ever observed animal creatures that are neither flesh, nor fish, but of an intermediate degree between both? Truly, answered both the Fish- and Worm-men, we have observed several animal creatures that live both in water, and on the earth, indifferently, and if any, certainly those may be said to be of such a mixed nature, that is, partly flesh, and partly fish: But how is it possible, replied the Empress, that they should live both in water, and on the earth, since those animals that live by the respiration of air, cannot live within water; and those that live in water, cannot live by the respiration of air, as experience doth sufficiently witness. They answered her Majesty, that as there were different sorts of creatures, so they had also different ways of respirations; for respiration, said they, is nothing else but a composition and division of parts, and the motions of nature being infinitely various, it is impossible that all creatures should have the like motions; wherefore it was not necessary, that all animal creatures should be bound to live either by the air, or by water only, but according as nature had ordered it convenient to their species.

The Empress seemed very well satisfied with their answer, and desired to be further informed, whether all animal creatures did continue their species by a successive propagation of particulars, and whether in every species the offsprings did always resemble their generator or producer, both in their interior and exterior figures? They answered, her Majesty, that some species or sorts of creatures, were kept up by a successive propagation of an offspring that was like the producer, but some were not. Of the first rank, said they, are all those animals that are of different sexes, besides several others; but of the second rank are for the most part those we call insects, whose production proceeds from such causes as have no conformity or likeness with their produced effects; as for example, maggots bred out of cheese, and several others generated out of earth, water, and the like. But said the Empress, there is some likeness between maggots and cheese, for cheese has no blood, nor maggots neither; besides, they have almost the same taste which cheese has. This proves nothing, answered they; for maggots have a visible, local, progressive motion, which cheese hath not. The Empress replied, that when all the cheese was turned into maggots, it might be said to have local, progressive motion.
