SECTION VI. 



INCLINATION, TOTAL FORCE, AND DECLINATION RESULTS DURING SOUTH-EASTERN SLEDGE JOURNEY, 



NOVEMBER, 1903. 



Observations for Inclination and Total Force were made by Mr. BEHNACCHI with Dip Circle No. 27. 



The Ice Station, McMurdo Sound, was used as a base station, and observations for Inclination and to 

 determine the Constant A, for reducing Total Force observations, were made here on November 8 as 

 follows : 



The results of these observations give the value of Constant A = log" 1 1-55706, which has been used in 

 reducing the Total Force observations. 



The observations for Inclination have been corrected for instrumental differences (see Section III.).
