Mayen ledsages ai' et "Pas-caert van Jan Mayen Eylant". 

 I den benyttede Udgave mangler desværre et Blad. paa 

 hvilket Beskrivelsen af Øens Nordside skulde være at linde. 

 En noget forkortet Oversættelse af denne Beskrivelse til 

 Tysk, som Professor Buijs Ballot i Utrecht har liavt den 

 Godhed at sende mig, slutter imidlertid med den Bemerk- 

 ning, at Beskrivelsen af Nordsiden mangler. Forøvrigt 

 beskrives i dette gamle Verk ( fstkysten helt fra Nordostkap 

 sydover og Vestkysten fra Sydkap nordover indtil Nordvest- 

 kap. Kartet, der aabenbart er det som ligger til Grund 

 for alle de senere Karter over Jan Mayen, forekommer 

 mig i sine Hovedtræk at være lige saa godt som disse. 



2. C. G. Zorgdragers alte und neue Gronlandische 

 Fischerei und Wallfischfang. . . . ausgefertiget dnrch Abra- 

 ham Moubach. Leipzig 1723. For Jan Mayens 'Vedkom- 

 mende har jeg i dette Verk ikke fundet noget mere end i 

 det foregaaende, der aabenbart er Kilden. 



3. An Account of the Arctic Regions. . . . by W. 

 Scoresby Jun. F. R. S. E. Edinburgh 1820. Til Grund 

 for Scoresby 's Kart ligger Zorgdragers. der aabenbart igjen 

 har til Kilde det gamle Kart i "Zee-spiegel". Hele Øens 

 Beliggenhed er rectiticeret af Scoresby, men i Detaljerne . 

 er det gamle Kart fremdeles det paalideligste.

 of a voyage. in 1856. in the schooner-yacht "Foani." to- 

 Iceland, Jan Mayen. & Spitzbergen. By Lord Dufferin.

Det Kart. som ledsager Vogfs Beskrivelse, er en 

 Copi af Scoresby's Kart. Det indeholder en Del Forbe- 

 dringer, men er paa den anden Side. navnlig i hydrografisk 

 Henseende, mindre fuldstændigt og correct end de ældre 

 Karter. Derimod have de Billeder af Partier af Jan 

 Mayen, der ledsage Vogfs Verk. været mig af overordentlig 

 stor Nytte, og for deres store Paalidelighed kan jeg inde- 

 staa. Endog mindre Træk i Landskabet har jeg efter disse 

 Billeder kunnet identificere. 



Til Grund for Constructionen af vort Kart er lagt 

 Scoresby's. Efter de af os foretagne Pejlinger og andre 

 Vinkelmaalinger har Gapt. Willé gjort et Udkast til Kystens 

 Form. og anbragt derved de hydrografiske Detaljer fra vore 

 Iagttagelser, saa langt de rak. og fra Scoresby. Efter det 

 Material, som stod til min Raadighed, heri indbefattet en 

 Række Skitser af Hr. Schiertz. vor Tegner. Professor Sårs 

 Og mig selv. har jeg forsogt at atkegge yderlige hydrografiske 

 Detaljer, dels elter "Zeespiegel". idet jeg fandt. at Beskri- 

 velsen og Kartet i dette var rigtigere end i de senere Verker. 

 dels ved Hjelp af Skitserne. elter hvilke' jeg kunde bestemme 

 noget sikrere enkelte Partiers indbyrdes Beliggenhed. navnlig 

 i Forbindelse med de verticale Dimensioner. Situationen

aimexed a "Pas-caert van .Tan Mayen Eylant." In the 

 edition I have constilted. the leaf on which an account of 

 the north coast of the island might have been looked for, 

 is unfortunately missing. A somewhat abridged translation 

 of this work into German, which Professor Buijs Ballot of 

 1'trecht had the kindness to send me. closes, ' however, with 

 the remark. that no account has been given of the north 

 side. For the rest. in this old volume the east coast is 

 described from Gape North-East soutlrwards. and the west 

 coast, from Cape South northwards to Cape North- West. 

 The map, which is manifestly that on which all later maps 

 of Jan Mayen are based, would appear in its main features 

 to be quite as correct as any of these. 



2. — C. G. Zorgdragers alte und neue Gronlandische 

 Fischerei und Wallfischfang. . . . ausgefertiget durch Abra- 

 ham Moubach. Leipzig 1723. As regards Jan Mayen. I 

 found nothing in this work that is not contained in the 

 foregoing, whence the author has evidently drawn his in- 

 formation. 



3. — An Account of the Arctic Regions . . . by 

 W. Scoresby Jun. F. R. S. E. Edinburgh 1820. Scoresby's 

 map is based on Zorgdrager's, which in turn is evidently 

 derived from the old map in the -Zee-spiegel.'' The position 

 of the island has. indeed, been rectified by Scoresby ; but in 

 all details the old map is still the most trustworthy.

The map annexed to Vogfs account of the Island is 

 a coj>y of Scoresby 's. It is. indeed. in some respects more 

 correct. but in others. more particularly as regar.ds the 

 hydrographical details. less complete and trustworthy than 

 the earlier maps. On the other hand, the views of the 

 Island accompanying Vogts work have rendered me the 

 greatest service: and for their accuracy. which is remark- 

 able. I can personally vouch. Even minor features of the 

 scenery, I have been able to identify from these excellent 

 illustrations.

 Wille has figured the contours of the coast. and sef down.

 hydrographical details. partly since I lind the account and

 of those given in later works on Jan Mayen, aud partly 

 with a view- to determine, by means of the sketches. with 

 greater accuracy the relative position of divers parts of
