Then the Empress commanded her Anatomists to dissect such kinds of Creatures as are called Monsters. But they answered her Majesty, That it would be but an unprofitable and useless work, and hinder their better imployments; for when we dissect dead Animals, said they, it is for no other end, but to observe what defects and distempers they had, that we may cure the like in living ones, so that all our care and industry concerns onely the preservation of Mankind; but we hope your Majesty will not preserve Monsters, which are most commonly destroyed, except it be for novelty: Neither will the dissection of Monsters prevent the errors of Nature's irregular actions; for by dissecting some, we cannot prevent the production of others; so that our pains and labour will be to no purpose, unless to satisfie the vain curiosities of inquisitive men. The Empress replied, That such dissections would be very beneficial to Experimental Philosophers. If Experimental Philosophers, answer'd they, do spend their time in such useless Inspections, they waste it in vain, and have nothing but their labour for their pains. Lastly, her Majesty had some Conferences with the Galenick Physicians about several Diseases, and amongst the rest, desired to know the cause and nature of Apoplexies, and the spotted Plague. They answered, That a deadly Apoplexy was a dead palsie of the Brain, and the spotted Plague was a Gangrene of the Vital parts: and as the Gangrene of outward parts did strike inwardly; so the Gangrene of inward parts, did break forth outwardly: which is the cause, said they, that as soon as the spots appear, death follows; for then it is an infallible sign, that the body is throughout infected with a Gangrene, which is a spreading evil; but some Gangrenes do spread more suddenly than others, and of all sorts of Gangrenes, the Plaguy- Gangrene is the most infectious; for other Gangrenes infect but the next adjoining parts of one particular body, and having killed that same Creature, go no further, but cease; when as, the Gangrene of the Plague, infects not onely the adjoining parts of one particular Creature, but also those that are distant; that is, one particular body infects another, and so breeds a Universal Contagion. But the Empress being very desirous to know in what manner the Plague was propagated, and became so contagious, asked, Whether it went actually out of one body into another? To which they answered, That it was a great dispute amongst the Learned of their Profession, Whether it came by a division and composition of parts; that is, by expiration and inspiration; or whether it was caused by imitation: some Experimental Philosophers, said they, will make us believe, that by the help of their Microscopes, they have observed the Plague to be a body of little Flies like Atoms, which go out of one body into another, through the sensitive passages; but the most experienced and wisest of our society, have
