16. The comet was rediscovered on August 18, 1903, by 

 Aitken at Mt. Hamilton, and was observed by him until January 

 14, 1904, a period of 149 days, during which the comet tra- 

 versed 60 degrees of its orbit. The comet was faint and small, 

 irregular in outline, and with but feeble condensation. Its 

 greatest diameter did not exceed three minutes of arc and at 

 the time of its discovery its brightness about equalled that of a 

 14th magnitude star. Later it faded greatly and became a diffi- 

 cult object to measure. During the whole of this period it was 

 invisible except with the aid of the largest telescopes. 



The following table gives the references to all observations, 

 published up to the end of April, 1904.
