Show Variety of Particles Gathered by the Eye Pew people have never experienced the puln rjj- discomfort that comes of getting dust panicles or other foreign bodies in the eyes. Few, It is safe to say, realize the true source of some of these irritating obstructions, Tell the average "riei'SOli' It is possible pos-sible to collect fn the eyes the dust of a falling star and you will probably be disbelieved. Yet microscopic examination ex-amination has shown this to be a fact. When a meteor reaches our atmosphere atmos-phere It discharges lieavy vapors, which condense into myriads of minute mi-nute particles, any one of which n.ay lodge in the eye that is gazing sky-' ward. Volcanic eruption may cause discomfort dis-comfort In u similar fashion. Lava flowing from an active crater gives off clouds of vapor containing microscopic particles that make their way round the world In the upper air currents, ultimately to fall in showers upon the earth, where wide-open eyes may easily collect them. Again, the great deserts contribute largely to the number of foreign bodies gathered in this way. Sandstorms Sand-storms do not cease from troubling immediately im-mediately they subside. Their particles are borne by the winds the world over, many of them finding lodgment in our eyes, as the microscope has repeatedly repeated-ly proved. Pollen from the big pine forests of Canada may affect us In like manner, while an evn more strange, though not less potent, cause of this special form of irritation is the scales of butterflies' but-terflies' wings, shed as a rule during the first flights after emerging from the pupa. The sources and variety of things gathered In the eyes during a normal lifetime are, In fact, amazing and form an astounding commentary on the disintegrating forces unceasingly at work in the universe. |
