En ctmstant Fejl af 10" i Eøjderne vil forandre den 

 beregnede Bredde saa meget som 10. "02 og den beregnede 

 Længde saa meget som 0.'52. Resultatet bliver saaledes 

 for Ankerpladsen paa Østsiden 



A constant error of l ( >" in the altitudes will change 

 the computed latitude as mach as 10."02, and the com- 

 puted longitude .-is much as 0/52. Hence, the result for 

 our anchorage off the east coast is — 



(f = 70" 58' 4. .". r 11. "4 



X = 8 24 .43. 7 + 41. = 0* 33™ 38.'9 ± 2.*73 W. Greenwich. 



og for Fuglebergets Top 



and for the summit of the Fugleberg — 



Bredde (Latihide) 70° 59' 55" ± 11. "4 



Længde (Longitude) 8 27 22 ± 41. = 0' 33* 49.'5 ± 2.'73 W. Greenwich. 



Scoresby's Kart 1 , paa hvilket Fugleberget let kan 

 identificeres, lægger dette 1/6 nordligere og 31' (10 Kvart- 

 mil) østligere end min Bestemmelse. Scoreshv\ Ohserva- 

 tioner gjordes den 3die og 4de August 1817. I 1878 

 fandt den hollandske Expedition med Skonnerten "Willem 

 Barendsz '. at .Tan Mayen ligger vestligere end paa Scoresl>v's 

 Kart, Etter min Bestemmelse er Øen aflagt paa det af 

 ('apt. Wille og mig over samme udarbejdede nye Kart. 

 der følger senere i denne Generalberetning. 2 



Scoresbys Map, 1 6n which the Fugleberg may be 

 easily found, places that mountain 1/6 north and oL' il 1 ' 

 miles) east of my détermination. Scoreby's observatjons 

 were tåken on the 3rd and 4th of August 1817. In 1878, 

 the Dutch Expedition. with the schooner -'Willem Barendsz," 

 found the Island of Jan Mayen to lie farther west thau 

 it does on Scoresby^ map. Fur tlie new map of Jan 

 Mayen constructed by ('apt. Wille and myself, — to he 

 subsequently published in the-General Report, 2 — the posi- 

 tion of the island was laid down from my own détermination 

 of latitude and longitude.
