LX GEELMUYDEN. ASTRONOMICAL OBSERV. [\ORW. POL. EXP. No. 6.] 



the particulars of the determination of the longitude of this place; but in a 

 letter from Professor SCHIAPARELLI he is kindly informed that according to a 

 private letter from a member of the expedition of H. R. H. the DUKE OF THE 

 ABRUZZI, which had an excellent equipment of instruments, Lieut. GAGNI had 

 made a new determination of the longitude of Cape Flora and found a displace- 

 ment of 10' towards the east, which is not of importance in this connection. 

 The duke having left Arkhangel only 9 days before reaching Cape Flora, it 

 is very likely that a good determination could be made by means of the 

 chronometers. 



The two Charts, 



showing the track of the ship and of the sledge expedition, are constructed 

 on the stereographical projection. The scale indicated on the charts is valid 

 for latitude 81 11', but the difference for other latitudes is nearly insensible. 

 The magnetic declination, which is indicated by arrows in some places where 

 they could be inserted without inconvenience, is mostly taken from the observa- 

 tions by compass on the ice, but some values have also been furnished by 

 Mr. STEEN from observations in the magnetic observatory. 



The writer is under obligation to Professor H. H. TURNER of Oxford 

 who has had the great kindness to read a proof of this Introduction. 



In conclusion the writer cannot withhold an expression of admiration for 

 the activity and ability with which the men of the From have under most 

 trying circumstances and in a great measure with instruments and by methods 

 lying far outside their practice in former life collected so many important 

 scientific results.
