papers have more of the stamp of a genius. He has strong opinions on most subjects, and like most Irishmen, he is not afraid of a controversy. If Tait made a move and was not immediately successful, he was apt to retire resolved to have nothing further to do with it; not so Thomson; if baffled, he returns to the attack again and again. On social matters he has strong conservative opinions; at a club meeting after the regular meeting of the Royal Society of Edinburgh he was asked: "Sir William! what do you think?

This course of lectures, twenty in all, treated of the wave-theory of light, principally with the outstanding difficulties of the theory, and they partook largely of the nature of conferences.

He was also a member of the Commission which solved the problem of harnessing Niagara.
