218 Aftronomy and Geography. 
parpofe, was obliged to return, without haying accomplithed 
the objet of his miffion.. This circumftance, was,. u1 part, 
owing to the jealoufy of the Ruffians and other, European 
Powers; and befides, the French had then left two friends, 
men of confiderable intelligence, viz. the Vizier Halil Pa- 
cha, who: eftablifhed a {chool for artillery and engineering, 
and caufed the beft French works. on thefe fubjeéts. to be 
tranflated into the Turkith language, but who was beheaded at 
Fenedos ;, and the Vice-Admiral Captain Bey, who. poflefled 
a great miany afironomical and, nautical. infiruments, and 
‘who caufed Cit. de Lalande’s, abridgement of his afironomy, 
* to be tranilated into the Turkith language, but who was alfo 
decapitated in O&ober 1787. Cit. Beauchamp, however, 
was more fortunate, as he arrived on the 26th of June 1797 
at ‘Trebifonde ; and, without any impediment, was, enabled 
to determine the exact, pofition ofa great many points of 
the Black Sea. He found the latitude of Sinope ta be 42° 2’, 
inftead of 41 as it is laid down even in the beft maps ; fo 
that the very uncertain breadth of this fea, between Cape 
Karadaé and Cape Indgé, which was reckoned to be 63 
French leagues, appears to, be no more than thirty-feven 
leagues. The longitude of Trebifonde he found to be 
57° 16° 15”. According to a Turkifh map of the Black 
Sea, printed at Conftantinople in the year of the Hegira 11 355 
that is 1724 of the Chriftian era, there is an error of half, & 
degree of longitude in the pofition of this city ;, and in the 
map, of the Ruflian empire, publithed in 1776 by Trefcot 
and Schmid, thiserror extends to.a degree and ahalf. The 
calculation of the Jefuit P. de Beze_ is totally falfe, and too 
great by 72 degrees. Wemay, therefore, form fome idea of 
the fiate of geography in Turkey, and of the important fer- 
‘age of forty-eight. The latter is better known under the name of Le-. 
‘brun, and who for fome time held the office of minifter for foreign af- 
“fairs. His firft occupation, however, was that of an aftronomer; for’ 
he affsfled Caffini LEI. and IV. in the Obfervatory at Paris till the year 
3775, and mftruéicd im aftronemy his brother Achilles, who, died at 
Conftantinople in 1787, at the age of twenty-eight.
