[1] THERE is a certain sacrifice of very ancient institution, which the chief magistrate or archon performs always in the common-hall, and every private person in his own house. ’Tis called the driving out of bulimy; for they whip out of doors some one of their servants with a bunch of willow rods, repeating these words, Get out of doors, bulimy; and enter riches and health. Therefore in my year there was a great concourse of people present at the sacrifice; and, after all the rights and ceremonies of the sacrifice were over, when we had seated ourselves again at the table, there was an enquiry made first of all into the signification of the word bulimy, then into the meaning of the words which are repeated when the servant is turned out of doors. But the principal dispute was concerning the nature of it, and all its circumstances. First, as for the word bulimy, it was agreed upon by all to denote a great and public famine, especially among us who use the Aeolic dialect, putting π for β. For it was not called by the ancients βούλιμος but πούλιμος, that is, πολὺς λιμὸς , much hunger. We concluded that it was not the same with the disease called Bubrostis, by an argument fetched out of Metrodorus’s Ionics. For the said Metrodorus informs us that the Smyrnaeans, who were once Aeolians, sacrificed to Bubrostis a black bull cut into pieces with the skin on, and so burnt it. Now, forasmuch as every species of hunger resembles a disease, but more particularly bulimy, which is occasioned by an unnatural disposition of the body, these two differ as riches and poverty, health and sickness. But as the word nauseate ( ναυτιπαν) first took its name from men who were stomach-sick in a ship, and afterwards custom prevailed so far that the word was applied to all persons that were any way in like sort affected; so the word bulimy, rising at first from hence, was at last extended to a more large and comprehensive signification. What has been hitherto said was a general club of the opinions of all those who were at table.

[2] But after we began to enquire after the cause of this disease, the first thing that puzzled us was to find out the reason why bulimy seizes upon those that travel in the snow. As Brutus, one time marching from Dyrrachium to Apollonia in a deep snow, was endangered of his life by bulimy, whilst none of those that carried the provisions for the army followed him; just when the man was ready to faint and die, some of his soldiers were forced to run to the walls of the enemies’ city, and beg a piece of bread of the sentinels, by the eating of which he was presently refreshed; for which cause, after Brutus had made himself master of the city, he treated all the inhabitants very mercifully. Asses and horses are frequently troubled with bulimy, especially when they are loaden with dry figs and apples; and, which is yet more strange, of all things that are eaten, bread chiefly refreshes not only men but beasts; so that, by taking a little quantity of bread, they regain their strength and go forward on their journey.

[3] After all were silent, I (who had observed that dull fellows and those of a less piercing judgment were satisfied with and did acquiesce in the reasons the ancients gave for bulimy, but to men of ingenuity and industry they only pointed out the way to a more clear discovery of the truth of the business) mentioned Aristotle’s opinion, who says, that extreme cold without causes extreme heat and consumption within; which, if it fall into the legs, makes them lazy and heavy, but if it come to the fountain of motion and respiration, occasions faintings and weakness. When I had said that, some of the company opposed it, others held with me, as was natural.

[4] At length says Soclarus: I like the beginning of this reason very well, for the bodies of travellers in a great snow must of necessity be surrounded and condensed with cold; but that from the heat within there should arise such a consumption as invades the principle of respiration, I can no way imagine. I rather think, says he, that abundance of heat penned up in the body consumes the nourishment, and that failing, the fire as it were goes out. Here it comes to pass, that men troubled with this bulimy, when they are ready to starve with hunger, if they eat never so little meat, are presently refreshed. The reason is, because meat digested is like fuel for the heat to feed upon.

[5] But Cleomenes the physician would have the word λιμός (which signifies hunger) to be added to the making up of the word βούλιμος without any reason at all; as πίνειν, to drink, has crept into καταπίνειν, to swallow; and κύπτειν, to incline, into άνακύπτειν to raise the head. Nor is bulimy, as it seems, a kind of hunger, but a fault in the stomach, which concurring with heat causes a faintness. Therefore as things that have a good smell recall the spirits of those that are faint, so bread affects those that are almost overcome with a bulimy; not that they have any need of food (for the least piece of it restores them their strength), but the bread calls back their vigor and languishing spirits. Now that bulimy is not hunger but a faintness, is manifest from all laboring beasts, which are seized with it very often through the smell of dry figs and apples; for a smell does not cause any want of food, but rather a pain and agitation in the stomach.

[6] These things seemed to be reasonably well urged; and yet we thought that much might be said in the defence of the contrary opinion, and that it was possible enough to maintain that bulimy ariseth not from condensation but rarefication of the stomach. For the spirit which flows from the snow is nothing but the sharp point and finest scale of the congealed substance, endued with a virtue of cutting and dividing not only the flesh, but also silver and brazen vessels; for we see that these are not able to keep in the snow, for it dissolves and evaporates, and glazes over the outmost superficies of the vessels with a thin dew, not unlike to ice, which this spirit leaves as it secretly passes through the pores. Therefore this piercing spirit, like a flame, seizing upon those that travel in the snow, seems to burn their outsides, and like fire to enter and penetrate the flesh. Hence it is that the flesh is more rarefied, and the heat is extinguished by the cold spirit that lies upon the superficies of the body; therefore the body evaporates a dewy thin sweat, which melts away and decays the strength. Now if a man should sit still at such a time, there would not much heat fly out of his body. But when the motion of the body doth quickly heat the nourishment, and that heat bursts through the thin skin, there must necessarily be a great loss of strength. Now we know by experience, that cold hath a virtue not only to condense but also to loosen bodies; for in extreme cold winters pieces of lead are found to sweat. And when we see that bulimy happens where there is no hunger, we may conclude that at that time the body is rather in a fluid than condensed state. The reason that bodies are rarefied in winter is because of the subtility of the spirit; especially when the moving and tiring of the body excites the heat, which, as soon as it is subtilized and agitated, flies apace, and spreads itself through the whole body. Lastly, it is very possible that apples and dry figs exhale some such thing as this, which rarefies and attenuates the heat of the beasts; for different things have a natural tendency as well to weaken as to refresh different creatures.
