General Mean. 



69 24-11 



Each of the numbers, both in Captain Johnson's and Major 

 Sabine's observations, is a mean of the readings of the two ends 

 of the needle. In the azimuths and 180° each niunber is also 

 a mean of two distinct observations, between which the needle 

 was raised from its support.s, and lowered afresh. At all the 

 other azimuths one such observation by each of the observers 

 was considered sufficient. The total number of readings is 224 

 by each observer.
