 There being at this time a great want of ephemerides of any tolerable exact- 

 ness, several of our astronomers were persuaded to undertake the calculation of 

 one for this present year, which they have done from tables of their own, whose 

 numbers, by many years observation, have been found to answer with great 

 preciseness to the celestial motions, the moon only excepted ; whose motion, 

 by reason of her manifold inequalities, not being yet reduced to the nicety of 

 the rest of the planets, it was thought needless to do any more than reduce her 

 tychonic place in Argol, to our meridian, and compute the true latitudes. The 

 several persons concerned have promised a continuation thereof for some years 

 to come, which will make it valuable to all lovers of astronomy. 



Account of a Journey of the Emperor of China into the Eastern Tartary, 

 Anno l682. By Father Ferbiest, Missionary to Pehin. N° 180, p. 39. 



The Emperor of China made a journey into the Eastern Tartary in the 

 beginning of this year l682, after having quelled a revolt, by the death of three 

 rebellious kings, formed in some provinces of the empire : one of these princes 

 was strangled in the province of which he had made himself master : the second, 

 being brought to Pekin, with the principal heads of his faction, was cut to 

 pieces in the sight of the whole court : the most considerable Mandarines act- 

 ing with their own hands in this sad execution, to revenge upon this rebel the 

 death of their relations, whom he had caused to be cruelly murdered. The 

 third, who was the most considerable, and indeed the head of the revolt, had» 

 by a voluntary death, prevented his deserved punishment, and so put an end to 

 .a war, which had lasted for 7 years. 



Peace having been settled, by the re-establishing in the empire, and all the. 

 provinces, the peaceable enjoyment of their ancient liberties, the emperor de- 

 parted the 23d of March, to go into the province of Leao-tum, the country of 

 his ancestors, with a design of visiting their sepulchres, and, after honouring 

 them with the usual ceremonies, of prosecuting his journey into the Eastern 

 Tartary, a journey of about 1 100 miles from Pekin. 



The Emperor took with him his eldest son, a young prince of lO years of age, 

 who already had been declared heir of the empire. The three principal queens 

 went also this journey, each in her gilded chariot ; as also the principal kings 

 which compose this empire, accompanied by all the grandees of the court, 

 and the most considerable Mandarines of all the orders ; who having all a great
