EBRICCATUM, a term ufed by Paracelfus to exprefs the par- tial ldfs, or deprivation of reaSon, as it happens during drunkenneSs, but with the addition of -the epithet ceelejle it fignifies, with the fame author, a much more exalted State, aYort of divine enthufiafm, or infpiration, fuch as the Sybils ofoldboafted of, and, among the moderns, the French pro- phets, and fome other religious feels have pretended to. Paracelfus himfelf pretended, at times, to be be under fome fuch influence, but his mad fits feemed to have very little of inspiration in them. EBR1LLADE, in the manege, a check of the bridle, which the horfeman gives to the horfe by a jerk of one rein, when he refufes to turn.

Guillet. -EBRIZIUS Color, a term ufed, by fome of the oW writers, to exprefs a very fine yellow. The word feems originally to

rum obryzum, or fine gold, of which this Ehrizius expreffed the colour. 'EBSEMECH, in chemiftry, a word ufed by Langius, and

fome other authors, for quickfilver. EBULLITION of the Blood, Ebullitio Sanguinis, in medicine, a term ufed by fome of the old writers, to exprefs what they fuppofed to be the occafion of the motion of the heart, which they attributed to a fort of Ebullition of the blood contained there. Dr. Lower was the firft who wrote againft this ifyftem, and proved not only that this Ebullition would be inef- fectual to the end propofed by it, as it would be as great an obftacle to its fyftole, as they expected it to prove an afliftance to its diaftole ; but that the heart evidently owed all its mo- tions to its fibres and nerves, the motion of it being in all things conformable to that of other mufcles, and no more unintelligible than theirs. The whole motion of the heart indeed is its fyftole, for the diaftole is no other than its refti- tution. There is a neceflary commerce between the heart and brain, but both ultimately depend upon the ftomach, as the conftant purveyor and furnilher of the matter both of blood and fpirits. Phil. Tranf. N°. 45. All the blood in the body pafles thro' the heart thirteen times in an hour ; and the florid colour of the arterial blood, which Jias been fuppofed by the arguers for the ebullitio Sanguinis to proceed from fuch another principle, the accenfion, as they call it, in the heart, arifes from the admixture of air with 4t in the lungs. The change of chyle into blood is an- other thing which has greatly perplexed thefe writers, and of which they have given as erroneous accounts as of the reft. It is certain, that nothing pafles from the fpleen through the yas breve into the ftomach, but that the ferment of the fto- mach proceeds immediately from the blood itfelf ; the fepara- lion of the chyle is performed in the inteftines, and to facili- tate its pafTage, it is diluted and refined by the juice of the cancreas Secreted intp the duodenum^ This chyle is, by the (Suppl. yoj.

r'oflile ivory, and the bones of other animals, are frequently found bury'd at great depths in the earth, and are found to have preserved their fubftance, texture, and colour in different degrees, according to the nature of the matter they happen to have lain among. Sometimes they are firm and folid, and fcarce altered in colour, and fometimes more or lefs hardened, and tinged to different colours by the different matter they have Iain among.

Of this kind was the Spotted foflile ivory of the antients, which was in all refpects the fame with our rough turquoifes of many places, which are no other than the teeth and bones of animals accidentally lodged in the way of particles of cop- per. Thefe are tinged more or lefs perfectly with a green or blue colour from thefe particles, and are often found of their native whitifh caft in the greater part of their fubftance, and only ftreaked and fpotted with Small variegations of a deep blue, which, by the aififtance of a proper degree of heat, is' diflodged from thefe particular places, and diffufed through the whole fubftance, tinging the whole with a fine pale blue. T he antients have not been perfeaiyunderftood in theirdefcrip- tion of this foflile ; for the Greeks, exprefling its variegations by the word yAh.w\, which is ufually translated black, Pliny- copies them in that SenSe, and from him all the world have declared the variegated foflile ivory of the antients, to be black and white. Theophraftus however is the firft who ex- prefles the colours of this fubftance by the word p&ixiij, and the fame author, Soon after exprefling the male Sapphires, or thofe of a deeper blue, by the fame word ; it is evident he could not mean by it any other than a deep blue, and plainly that what they called their variegated foflile ivory, was no othej; than the rough turquoife. They Seem however not to have" known the art of diffufing the colour through this fubftance by fire, and So converting it into a fine turquoife; but what they called callais was a turquoife of another kind, the bo- tryoide copper ore, now ufually called alfo by the name of that gem.
