QUID, What, in the Schools, is iifed to denote the de- 

 finition of a thing.

The name is derived hence, that it is by the eflence of a

 not another. When upon feeing, or hearing, the name of a 

 thing, with whofe nature, &c. we are unacquainted, we aflc. 

 Quid ejl? What is it ? we mean no more by the interrogation, 

 but that we defire to have its nature and eflence explained by 

 a definition. Whence quiddity is ufually defined the eflence 

 known orexprefTed in a definition. 



And hence what is efiential to a thing is faid to be quid- 

 ditive ; as quidditive knowledge, &c.

 four grand patriarchates of Conilantinople, Alexandria, 

 Antioch, and Jerufalem ; prefents a geographical defcrip- 

 tion of each diocefe, and of the epifcopal cities, and then 

 gives a particular account of the origin and eftablidiment of 

 the churches, their extent, their jurifdiftion, their rights, 

 their prerogatives, the fucceflion and order of their bifhops, 

 their political government, the changes which they have un- 

 dergone," &c. As the author did not live to finifh his work, 

 it was publifhed with additions, in the year 1740, under the ' 

 title of " Michaelis le Quien Oriens Cliriltianus, in quatuor 

 Patriarchatus digeilus, qua exhibentur Ecclefias, Patriarchae, 

 csterique Prefules Orientis," &c. in 3 vols. fol. Moreri.

 tenfe contemplation, endeavoured to arrive at a tranquillity of 

 mind entirely free from every degree of tumult and pertur- 

 bation. Thefe Quietifts, in conformity to an ancient opinion 

 of their principal dotlors, (who imagined that there was a 

 celeitial light concealed in the deepeft retirements of the 

 mind,) ufed to fit every day, during a certain fpace of time, 

 in a folitary corner, with their eyes eagerly and immoveably 

 fixed upon the middle region of the belly, or navel ; and 

 boatted, that, while they remained in this pofture, they 

 found, in effeft, a divine light beaming forth from the foul, 

 which diffufcd through their hearts inexprefiible fenfations of 

 pleafure and delight. To fuch as inquired what kind of light 

 this was, they replied, by way of illuilration, that it was 

 the glory of God, the fame celeftial radiance tliat furrounded
