Show t 1 the tho visible globe odthe of the eun sun ie is times larger than the e earth jtb says prof R A proctor in i laganne Ma ganne within tie the euri ouri iw face so seeni he continue continues

while no astronomer doubts f 1 that thase other elements which have 0 lotsis not M ts yet been detected in the sun are really present in his saw WAS now have we any evidence as to the way in which the mighty mass of the sun is disposed within that 9 1 surface which what we 0 term his volume though in reali ty one can hardly eay say what hie his 0 volume is seeing that there areber are per bione

are ars three lines on which we can seek for an answer to these qu es lione we find that the visible surface of the sun run behaves idalain in aman ner utterly inconsistent alike with I 1 the idea that this surface is near the real surface of an a interior globe and with the idea that the visible surface ii part of a mighty vesicle or bubble the pot spot zone zones are car ried riad around at different rates ac lt C cording to their distance from the equatorial solar region regions not to follow faye and othere others in niceties 2 3 1 0 of o calculation far from justified by the evidence we have I 1 may say that the equatorial zone gains about bout one rotation in seven on the pot zones or roughly iome mile miles in days bay say miles per day such a Telo velocity city as this close 1 to ten mile miles a minute could not possibly po sibly exist in a cloud laden region auch such as the visible of the cun sun undoubtedly ia is and ad aa as affecting region regions exceeding the whole surface of the earth thousand of times unless the cloud C t laden region waa was far away from the region of the sun and there fore from the friction ea effects of the true colar iolar rotation the real mai mass of the un sun however distributed can only rotate aa as one tho the visible cloud surface has many rate rates of rotation therefore must be an enor mou distance between the two secondly
