Remarks, 
chiefly to illustrate some of the 
Observations. 
By the observations of November, &c. it 
seems probable it had not obtained its full 
brightness before December io, although 
possibly much later. 
The increase towards July 27 was so 
slight that I had much hesitation in adopt- 
ing it as a full brightness ; if omitted, the 
interval will be 91 days. See Phil Trans. 
- 1 797 - 
r The full brightness in May is doubtful 
to only about 6 days ; the observations 
A regular succession of observations 
were made between July and October 25. 
The last observation made, was on De- 
The full brightness lasted a fortnight. 
r The observation of July 14, is doubtful 
•i to a few days, to which perhaps the excess 
(_ may be attributed. 
r A regular succession of observations 
\ were made between September and the 
< middle of November. This last determi- 
4 nation was deduced after the first part of 
V^this Paper was finished.
