Hence we may learn, how it is that nature, in our bodies, converts vegetable into animal fubftances ; and it is verv remarkable, that not a grain of fixed fait can be procured from this putrijied mats.

Putrefaction of water. It is faid to be the peculiar quality of the Thames water, that it will (link and yet be wholefome ; and after this will recover itfelf again. Many failors have been obliged to drink it {linking, fo that they held their nofes while they poured it down their throats, yet no ficknefs en- fued from it. It generates a fort of fpirit alio in this {linking ftate, which will take fire at the approach of a lighted candle as if fpirit of wine were touched by the fame.
PUTTOCKS, or VuTTOCK-Jhrsuds, in a fhip, are fmall fhrouds which go from the fhrouds of the main-maft, fore-malt, and mizen-maft, to the top-mall fhrouds ; and if there be any top-gallant-mafls, there are pultoek s to go from the top-mail fhrouds into tbefe. TheCe puttoeh are at the bottom feized to a ftaff, or to fome rope which is feized to a plate of iron, or to a dead-man's eye, to which the lanniards of the fore-maft fhrouds do come.

PYCNI, mow, in the antient mufic, was ufed for fuch founds or chords of a tetrachord as might enter the fpiffum, or vrvxvw.
Thefc were the hypatae a , the parypatas b , and the lichani % of the feveral tetrachords. The hypata were called barypyeni, fiufvuvxHH the parypatce mefopyeni, tumvuxmr, and the lichani exypyeni, Qtrnmaf. becaufe the firft were the loweft notes; the fecond, the middle notes; and the third, the higheft of the fpiffum J . Such chords as could never enter the fpiffum were called apyeni, u.kvkw. [ a [/waroa&is. b vafimctTouSas- c 7Wj£««i&«. d Wallis's Append, ad Ptolem. Harm. p. 165.] Hence in the Greek fcale or diagram % containing eighteen chords, there were five barypyeni, as many mefopyeni, and an equal number of oxypyeni, together with three apyeni. The apyeni and barypyeni were ftabiles or fixed chords ; but the me- fopyeni and oxypyeni were moveable, or mobiles b . [ a See Diagram. b IVallis ityd. p. 165, 166.]

PYGARGITES, in natural hiftory, a name given by Pliny and fome other of the old writers to the eagle-ftone, when it was variegated with white, in the manner of the tail of the eagle called pygargus.
Some have called this Hone pygarus, and others have applied the name to a ftone very different from the ac'tites, and only refcmbling the colour of the eagle. From hence it has hap- pened, that two very different flones have been confounded together ; but the virtues of both being merely ideal and ima- ginary, the world is not greatly the worfe for the want of the neceffary diflin£tions.
PYGARGUS, a fpecies of eagle, called alfo by fome authors albicilla, and ilianularia.
It is a large and fierce bird, of the fize of a common turkey. Its beak is yellow, and covered with a yellow membrane at its bafe. It has large hazel-coloured eyes. Its feet are yellow, and its claws extremely ft rang and fharp. The head is white, and there are no feathers, but fome fine hairs between the eyes and noltrils. The upper part of the neck is of a reddifh brown, and the rump black : all the body befides this is of an obfeure rufl colour, and its wings are partly black, partly grey. Its tail is long, and the upper half of it is white, and the reft black. It is from this white part that it has its name albicilla.
Authors who have written on this fubjed feem not all agreed to call the fame bird by this name. The pygargus of Aklro- vand feems different from this, and the pygargus prior of Bel- lonius feems no other than the male of that kind of hawk called in EngHfh the hen-barrier. Willughbfs QrnithoL p. 31 Pygargus acctpiter, in zoology, a name by which many au thors have called the fubbuteo, a bird of the hawk kind ; the male of which is called in Englifh the hen-harrier, and the fe- male the ringtail.

PYLORUS (Cycl.) — Kcrki ing gives us an account from his own knowledge of the entire ftoppage of this part, by a Dutch (li- ver accidentally fwallowed, the confequenre of which was the death of the patient in a few days. On the. other hand, he mentions an inftance of another, perfon's fwallowjng a copper coin, which without any other effect than violent naufeas and ficknefs, was, at the end of about a month, difcharged by- purges ; but fo corroded by the juices of the ftcmach, that it was fcarce to be known, all the letters and marks being eaten down to the fame common furface on both fides.

PYRAMIDAUS (Cycl.)— Pvramidaif.s abdominis. Thefe are called fuccenturiati by Fallopius ; they are fituated on the lower part of the recti, and feem only a portion or appendix of it. They are partly inclofed within the vagina of the recti, running clofe by each other along the linea alba, to which they are fixed at different diftances by oblique tendinous indentations, the uppermoft of which was fometimes very long. When thefe mufcles are wanting, the lower extremities of the recti are always thicker than ufual: often there is only one found, and fometimes, tho' rarely, three. lVmjkw\ Anat. p. 1 (•> 8.

PYRETHRUM [Cycl)— Pyrethrum, in the materia medica, a root of which the druggtfls fell us indifcriminately two kinds ; the one the root of a corymbiferous plant, called by authors pyrethrum flore BeUidis, or the daily-flowered pellitory of Spain ; the other, the pyrethrum umhellfierum, or umbelliferous pelli- tory : and it is a difpute among the learned, which of the two is the genuine and proper kind. The description left us of it by Diofcorides, as it is differently written, fervino- as well to prove the one fo as" the other.
The roots of the daify-flowcred pellitory are what we moft frequently meet with. They are of three or four inches lon<r, of the thicknefs of one's little finger, greyifh and wrinkled without, and whitifh within, and of an acrid and burning tafte. Thofe of the umbelliferous pellitory are of the fame length, but fomewhat thinner, of a hrownifh grey without, and white within, and are furnilhed with a fort of beard at top, fomewhat like the roots of the mcum. It is of an acrid tafte, and much refembles the other in its virtues. They are both ufed in the tooth-ach, and are prefcribed by fome in dff- eafes of the head and nerves, and are found to be diuretic and violently fudorific, but they are very feldom given.
PYRGUS, among the Romans, a dice-box of the fhape of a medius, open above, and having a great many fhelves or partitions within it ; fo that when the dice were thrown into it out of the frittillum, they were thereby over- turned many times before they could reach the bottom, in which there was an opening for them to fail through upon the table.
