The comparifon of the following refults, deduced
from correfponding observations * of the eclipfes of Jupiter’s
Satellites taken at Bolcherelk at the port of Peter
and Paul by KraffilnikofF, and at Pekin by the Jefuit mif-
fionaries, will ftiew from their near agreement the care
and attention which muft have been given to the.observations
; and from hence there is reafon to fuppofe, that
the fufpicions o f , inaccuracy imputed to KraffilnikofF
are ill founded.

In the-fame manner the longitude-of Bolcherelk appears from the correfponding
obfervations taken at that place and at Peterfburg to be
ioh. 20'- 22" differing from Mr. Maraldi about 2' 5". Nov. Com. p. 469.
But the longitude of-the port o f St. Peter and Paul, eftimated in the
fame manner from correfponding obfervations, differs from the longitude
as computed by Monf. Maraldi no more than 20 féconds, p. 469.
