 siderable changes in respect to figure, yet it appeared strong enough 

 to last another revolution, by which means more favourable oppor- 

 tunities may offer to obtain the number of hours (if any) in addi- 

 tion to the first observed 27 days of its revolution. It appears from 

 a drawing of the positions of this spot, and another large one that 

 accompanied it, whose declination was about 19 degrees South, that 

 in their daily progress across the sun's disc they moved in slightly 

 parallel curved lines from East to West, and went off nearly at the 

 same time ; therefore they will probably appear on the sun's eastern 

 limb at noon of the 9th of July. Since the 27th of May, consider- 

 able variations and alterations have taken place in the positions and 

 number of the solar spots ; some have entirely disappeared, while 

 new ones have appeared on other parts of the sun's disc.
