Rowland, after Maxwell’s determinations, equal to 28,800 millions, 
, Weber's value would be 31,074 mi illions. I give "below under

calculated with the latter.

measurement of a force which amuunts to only sp3o0 © 
of the earth’s magnetism, since in two of the series the observed 
values fall between those corresponding to the different measured 
values of Weber’s constant. '
