 From Observations by Lieutenant ARMITAGE with Lloyd-Creak Circle No. 143. 



It is satisfactory corroboration of the method of reduction that the result of the observation made by 

 Mr. BERNACCHI, January 31, when the ship's head was S. 71 W., is in close agreement with the result of 

 the observation by Lieutenant ARMITAGE, February 1, in nearly the same latitude and longitude, when 

 the ship's head was S. 55" E.

INCLINATION RESULTS. 



From Observations made by Mr. BERNACCHI and Lieutenant ARMITAGE on board the " Discovery " at Sea, 



in the Antarctic, February and March, 1904. 



The instruments used were : 



By Mr. BERNACCHI, Fox Circle No. 29. 

 Lieutenant Armitage, Lloyd-Creak Circle No. 143. 



The instrumental differences were ascertained by comparison of instruments at the Ice Station, McMurdo 

 Sound (see Section IX.). 



The "Discovery" was swung for deviation of the compass, February 21, 1904, in latitude 74 26' S., 

 longitude 165 30' E. The resulting coefficients of the deviation were as follows, the notation being that 

 of the ' Admiralty Manual of Deviation of the Compass ' : 



A. 

 



B. 



- 2 48' 



C. 



-3 or 



D. 

 



E. 

 



The remarkable difference between these results and those obtained in the year 1902 (see Section IX.), 

 in approximately the same locality, indicates that the magnetic conditions at the compass position in the
