The 118th Article. Of Tremblings.

TRemblings have two severall causes: one is, that there come sometimes too few spirits from the brain into the nerves; the other, that there come sometimes too many, so that the lit∣tle passages of the muscles cannot be duly shut, which as hath been said in the eleventh Article, ought to be shut to determine the motion of the members; the chiefe cause of it appears to be in Sadness, and fearfulness; as also when a man shakes with cold; for these Passions, as well as the cold of the aire, may so thicken the blood, that it may not furnish the brain with spirits enough, to send any into the nerves; the other cause appears often in those who ardently desire any thing, and in those who are moved with wrath, as also in those who are drunk, for these

two Passions, as well as Wine, sometimes make so many spirits go into the brain, that they can∣not regularly be conveyed from thence into the muscles.
