needed here and to some of them at last least consent could not now be obtained stars stare recorded by photography the number of tars stars recorded on a plate depends anol no only on the region of the heavens to which the tele telescope la Is directed but on the length of exposure at the bonn observatory atory a map of the northern heavens was made showing every star visible in a small telescope ot of about three inches aperture it we rail call the number of stars shown on this map unity the photographs with an eleven inch telescope show that in twenty seconds three and a half times as many stars are recorded in six minutes fifteen and a half halt times as many and in forty minutes seventy three times as a many by increasing tho the exposure more stars are visible but the increase c r ca se Is not indefinitely great so tar far as these observations go they show either that the number of stars Is hot lot infinite or that the light of stars Is absorbed in space
