Results of Magnetical Observations, 1875-76. [May 8, 



Assuming the mean inclination = 84° 50' ~N. daring the period when 

 the horizontal force was observed as above at Winter Quarters Obser- 

 vatory, the total force = 12* 559. 



At Winter Quarters Observatory the mean values of P or coefficient 

 of magnetic distribution for the unifilar magnetometer were at dis- 

 tances 1*3 to 1*6 feet -4- "0515 from the observations in October, 

 November, December, and 4- '0270 during the last three months. 

 With a mean temperature of + 25°, log 7r 2 h = 1*656981.

In computing the horizontal from the total force the values of the 

 inclination have been taken from those observed about the tine of the 

 force observations.
