the unhappy instance of the same kind of contagion, which happened at the session in the Old Baily in May 1750, see Dr. Pringle’s excellent work, intitled, _Observations on the Diseases of the Army in Camp and in Garison_[144]. XCVI. _A Description of the Plan of_ Peking, _the Capital of_ China; _sent to the Royal Society by Father_ Gaubil, è Societate Jesu. _Translated from the_ French. KING CHE. THE COURT. [Read June 1, 1758.] IN this plan are the inclosures of walls, which form as it were three cities. [Kong tching, Tse kin.] The first is the imperial palace, or imperial city. It is called _Kong tching_ or _Tse kin_. The numbers 11, 17, 21, 24, mark the great gates of this inclosure. [Hoang tching.] The second inclosure is _Hoang tching_. The numbers 3, 18, 30, 86, mark four great gates of this inclosure. [King tching.] The third inclosure is _King tching_, or Royal City. The numbers 235, 1, 99, 146, 173, 183, 188, 109, 211, mark nine gates of this inclosure. At the four angles east and west of the north and south walls is a large pavillion in the form of a fortress. It is a kind of arsenal or magazine of arrows, bows, guns, bucklers, cuirasses, pikes, small cannon, _&c._ Observe the angle made by the inclosure _Hoang tching_ on the south of the gate Nº. 84, to the north of Nº. 260. The inclosure extends to the east, then to the south, and continues to the east, passing by Nº. 3. [Illustration: _Philos. Trans. Vol. L._ TAB. XXIV. _p. 704_. _J. Mynde sc._ ] [Illustration: _Philos. Trans. Vol. L._ TAB. XXV. _p. 704_. _J. Mynde sc._] 1. is the great gate _Hien men_. As you go on to the north, 2, 143, 214, are three gates of a great court with magnificent walls. Thro’ the gate 3 you enter into a court, where is the _Tay miao_ Nº. 7. There are reposited the tablets of the ancestors of the reigning emperor, and of the illustrious subjects deceased, who have served the dynasty. This _miao_ or palace is a vast one, and well kept. At regular times the emperor, princes, and great men, go thither to perform ceremonies. Nº. 9 is the _Che tsi tan_, where are performed, at regular times, the ceremonies to the ancients, who have taught the art of agriculture. This palace is a very beautiful one. 4, 5, 6, are the gates of a court, where the _reguli_ and princes go frequently to receive the emperor’s orders. There are halls for their reception. The mandarins give them tea to drink, and mark their names in a register. When upon the fixed days they cannot attend, they are required to give notice of it. It is in this court, that the tributary princes, or their envoys, do homage, and receive the presents of the emperor; which presents are considered as rewards.
