Show SHUT OUT WATER AND DUST Nature Has Provided for the Hermet-ical Hermet-ical Closing of Nostrils of Seal and Camel. Most of us w hen we go In for diving have the very unpleasant experience of getting our nostrils full of water. Nature did not design man to be a diving animal, otherwise she would have been us clever with his nose as she has been with seal's, London Tit-Bits Tit-Bits sajs. The seal i.s, without doubt, the cleverest clev-erest diver in the animal world, and his nose Is a very Ingenious contrivance contriv-ance Indeed. Kach nostril is provided w ith muse'es which close It herinetlcal ly at the owner's will. And the shape el' the nose is such tl'.at when the nos-nils nos-nils are closed not a drop of water can enter. With seals the closing of the nostrils at the moment of diving has become an automatic process. This is wonderful enough, but we can : ee a Mill more remarkable appll-i appll-i ii t inn of Ihe same principle in an ani mal as far removed from the seal as c.'ia'k Is from cheese. The seal Is a wntor .iiiilmal. The other owner of trapdoor nostrils Is the camel, an h habitant of the dries, parts of the world, the waterless sandy deserts. Now. why should Ihe camel require such an apparatus? He Is not 1 1 cabled with water, but he Is troubled trou-bled with dusl ; not the dust that we see In this country, but the tierce, blinding duststorms of the desert. These are so violent flint tiny particles par-ticles are driven Into the works of even the most finely made w atch, w hich becomes at once dogger, and useless If the camel had not nostrils which were rfeelly dust-tight lie (ould never emliiie the dreadful sand and I dut storms. |
