Famiharised by daily imtimacy with any recognised fact or phenomena, however grand its discovery, the mind ceases to wonder. We lose the power, or rather the habit of appre- ciating it in its early grandeur, forgetful of the mtellect that has been employed in developing it, and it takes its place in a prominent position in the great temple of science, to support the superstructure of yet more recent discoveries.
