MR. RUMKER'S OBSERVATIONS 



Remark. — During the total eclipse (May 21, 1826,) the darkness was so com- 

 plete, that occultations of stars of the eighth magnitude behind the eclipsed 

 moon could conveniently be observed. I observed only one, as follows : 



Immersion -. 12 34 38 



Emersion 12 48 41 



The position of this star is about • r r* i i q ar 



Aristarchus was towards the latter part of the eclipse as brilliant as a star of 

 the first magnitude. In the beginning I found nothing particular about him.
