[To THE EDITOR OF THE "SPECTATOR...3

Wallace's argument against the infinity of the universe may be met by reminding hint that not all celestial bodies are luminous. We know this in the case of the dark companions to the variable stars, as well as in the case of our planetary system. It may well be that the non-luminous bodies are as numerous as the luminous. This would account for the more distant telescopic stars appearing rarer to us, as the greater the distance, the greater the mass of intermediate

non-luminous matter.—I am, Sir, &c., R. H. GAMLEN. New Place, Welwyn, Herts.
