th,
hair of animals, and other such things mix'd together; I thought it
probable, that they may by a kind of fermentation, produce those
_hollow greenish or reddish strokes in sight lower than the wall_ (or
within the surface)[59] which, as they in some measure resembled the
leprous scabs on the human body, were named the _Leprosy in a house_.
For bodies of different natures, very easily effervesce upon being
blended together. Wherefore we may reasonably suppose that this
moisture or mouldiness, gradually coming forth and spreading on the
walls, might prove very prejudicial to the inhabitants, by its
stinking and unwholesome smell, without having recourse to any
contagious quality in it. And somewhat analogous to this is pretty
frequently observable in our own houses; where, when the walls are
plaistered with bad mortar, the calcarious and nitrose salts sweat out
upon their surface, of a colour almost as white as snow. The power of
inspecting their houses was invested in the priests; who, when they
observed this foulness, gave orders first to have the walls of the
house scraped all around; and afterwards, if it continued to break
out, to pull down the house, and carry the materials out of the city
into an unclean place.

I am well aware, that all this is related, as if God himself had
struck the house with this plague. But it is well known, that that way
of speaking is not uncommon in the jewish history; as in unexpected
evils and dreadful calamities, which are sometimes said to be done by
the hand of God, tho' they may be produced by natural causes. Nor can
I be easily induced to believe, with some divines, that God, who
commanded his people to be always free from every sort of
uncleanness, would vouchsafe to work a miracle, in order to inflict
this most filthy punishment on any person. Thus much is indubitable,
that the precepts of the mosaic law were constituted particularly, to
avert the people from idolatry and false religion, and at the same
time to keep them clear of all uncleanness.[60] To this end conspired
the prohibition of eating blood, carrion, or animals that died
spontaneously, swines flesh, and that of several other creatures.[61]
For all these meats yield a gross nutriment, which is improper and
prejudicial in diseases of the skin.
