By Sir Oliver Lodge,* [This elementary paper has for its object the eliciting of anopinion, not the communication of a result.] THE two constants which regulate the properties andbehaviour of the aether so far as known, whetherthe phenomenon studied be electric, magnetic, or optical,are simplv and fundamentally defined thus, in terms ofactual mechanical force : — F = £ and ¥ = fjur- These definitions are independent of any system of units(t-. e. are true in all), so the dimensions of an electric chargeare e = ly/(KF) and of a magnetic pole m=lv/(fiF). We may also write magnetic moment ml—fiAI, A being-area and I being dejdt ; or we may equally well writem/e = fiv; which happens to be of the same dimensions as thecoefficient of electrical resistance.
