This array of names 5 will show the exceeding degree of uncertainty which 
hangs about the supposed magnetic results; and, notwithstanding the ela- 
borate experiments of Riess and Moser*, it does not appear safe, as they 
require of us ‘‘ to reject totally a discovery which for seventeen years has at 
different times disturbed science.”
