341. (4) Those things that are evil uses are effected by the operation of influx from hell, wherever there are such things as correspond thereto. The things that correspond to evil uses, that is, to hurtful plants and noxious animals, are cadaverous, putrid, excrementitious, stercoraceous, rancid, and urinous matters; consequently, in places where these are, such herbs and such animalcules spring forth as are mentioned above; and in the torrid zone, like things of larger size, as serpents, basilisks, crocodiles, scorpions, rats, and so forth. Every one knows that swamps, stagnant ponds, dung, fetid bogs, are full of such things; also that noxious insects fill the atmosphere in clouds, and noxious vermin walk the earth in armies, and consume its herbs to the very roots. I once observed in my garden, that in the space of a half yard, nearly all the dust was turned into minute insects, for when it was stirred with a stick, they rose in clouds. That cadaverous and putrid matters are in accord with these noxious and useless little things, and that the two are homogeneous, is evident from mere observation; and it is still more clearly seen from the cause, which is, that like stenches and fumes exist in the hells, where such little things are likewise to be seen. Those hells are therefore named accordingly; some are called cadaverous, some stercoraceous, some urinous, and so on. But all these hells are covered over, that those vapors may not escape from them. For when they are opened a very little, which happens when novitiate devils enter, they excite vomiting and cause headache, and such as are also poisonous induce fainting. The very dust there is also of the same nature, wherefore it is there called damned dust. From this it is evident that there are such noxious insects wherever there are such stenches, because the two correspond.
