In this memoir he cUfTents from the opinions of 

 MelTrs Engel and Vaugondy ; and defends the fyftem 

 of the Ruffian geographers in the following manner. 

 Monlieur Maraldi, after comparing the obfervations 

 of the fatellites of Jupiter, taken at Kamtchatka by 

 KraffilnikofF, with the tables, has determined the lon- 

 gitude of Ochotfk, Bolcheresk, and the port of St. Peter 

 and Paul from the firft meridian of Paris as follows : 



* Longitude of Ochotfk 9 23 30 



of Bolcherefic to 17 17 

 of the Port 10 25 5 

 Latitude of Ochotfk 59° 22', of Bolcherefk 52" 55', of 

 the Port 53° i'. 



The 



* KraffilnikofF compared his obfervations with correfponding ones 

 taken at Peterlburg, which gave refults as follow : 



From comparing an obfervation of an eclipfe of the firft fatcllite, 

 taken at Ochotfk the 17 th of January, 1743, with an obfervation of an 

 eclipfe of the fame fatellite taken at Peterlburg on the 15th of January 

 in the fame year, the difference of longitude between Peterfburg and 

 Ochotfk appeared to be 7''. 31' 29"; from a comparifon of two other 

 fimilar obfervations the difference of longitude was 7''. 313, a mean 

 of which is 7''. 31' 34 , being the true difference between the meridians 

 of Peterfburg and Ochotfk according to thefe obfervations. By adding 

 the difference of the longitude between Peterfburg and Paris, which is 

 i''. 52' 25", we have the longitude of Ochotfk from Paris 9^. 23' 59', 

 which differs 29' only from the refult of Monf. Maraldi. Nov. Comm.
