 the sun during the eclipse, and to compare the photographs with others of the

The above figure represents the results of the recent observations at Sobral. The lines drawn represent 

 in direction and magnitude the resultant shifts observed in the apparent positions of seven stars in the neigh- 

 bourhood of the sun. Lines drawn from the origin to the crosses represent the shifts calculated from 

 ranstein's theory. The observed shifts are in every case greater than the calculated ones — on the average 

 by about 14 per cent. The positions of the stars are not shown in the diagram. 



same field taken with the same lenses in England some months previously. 

 This eclipse was exceptionally favourable owing to the number of bright stars 

 in the neighbourhood of the sun. In the case of the Sobral expedition it was 

 possible to supply a further test by waiting until the sun had moved sufficiently
