Mn ROTHMAN-S OBSERVATIONS OF HALLEVS COMET. 499 



Two observations have been excluded: one because the Stars entry 

 was marked somewhat too late; the other, because the telescope received 

 a shght blow during the observation which may have displaced it. 

 Both of these on being reduced agree well, but I have thought it 

 safer to reject them. '^
