23 En constant Eejl af 10" i Hojderne vil forandre den beregnede Bredde saa meget som 10."02 og den beregnede Lamgde saa meget som 0.'52. Resultatet bliver saaledes for Ankerpladsen paa 0stsiden A constant error of 10" in the altitudes will change the computed latitude as much as 10. "02, and the com- puted longitude as much as 0.'52. Hence, the result for our anchorage off the east coast is — (f = 70° 58' 4."5 + 11."4 A = 8 24 43. 7 ± 41. 0 = O'* 33™ 38.‘9 ± 2.'73 W. Greenwich. og for Fuglebergets Top |J and for the summit of the Eugleberg — Bredde (Latitude) 70° 59' 55" ± 11."4 Ltengde (Longitude) 8 27 22 + 41. 0 z= 0h 33™ 49.'5 ± 2.‘73 W. Greenwich. Scoresby’s Kart1, paa hvilket Fugleberget let kan identiliceres, lsegger dette 1.'6 nordligere og 31' (10 Kvart- mil) ostligere end min Bestemmelse. Scoresby’s Observa- tioner gjordes den 3die og 4de August 1817. I 1878 fandt den hollandske Expedition med Skonnerten “Willem Barendsz”, at Jan Mayen ligger vestligere end paa Scoresby's Kart. Efter min Bestemmelse er 0en aflagt paa det af Capt. Wille og mig over samme udarbejdede nye Kart, der folger senere i denne Generalheretning.2 1 An Account of the Arctic regions. - Ogsaa publiceret i Petermann’s Mittheilungen f. 1878 Taf. 13 og i den nye Udgave af Stieler’s Hand-Atlas. Scoresby’s Map,1 on which the Eugleberg. may be easily found, places that mountain 1.'6 north and 31' (10 miles) east of my determination. Scoreby’s observations were taken 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 than it does on Scoresby’s map. Eor the new map of Jan Mayen constructed by Capt. Wille and myself, — to be subsequently published in the General Report, - — the posi- tion of the island was laid down from my own determination of latitude and longitude. 1 An Account' of the Arctic Regions. - This Map has already appeared in Petcnnann’s Mittheilungen for 1878, PI, 13, and in the new Edition of Stieler's Hand-Atlas.
