star, distant only about nineteen minutes of arc from the 
place of the nebula, was also variable. Ilis observations of 
the brightness of this star were as follow : — • 
•March 19. = 
10'4 magnitude 
October 18. = 
10T 
November 15. = 
9*9 
December 26. = 
9-6 - 
•January 23. = 
9-2 
These numbers show an apparently progressive increase 
of brightness ; but it is not improbable that a minimum 
occurred during the summer months, at which time no 
observations could be made, owing to the star’s proximity to 
the sun ; and therefore the actual range of variation may 
have been greater than that indicated by these observations. 
This star is No. 705, Zone + 19°, of Professor Argelan tier’s 
Bonner Sternverzeichniss , where its magnitude is stated to 
be 9'4. Its approximate mean place for 1860 - 0 is 
R.A. 4h. 18m. 40s. Declination north, 19° 28 /, 9. 
According to Professor Argelander’s system of nomencla- 
ture this variable will be called U Tauri. 
Mr. Baxendell also communicated the following observa- 
tions of the variable star near the edge of the nebula 
(T Tauri) 
1862. — March 19. T =. 10'8 magnitude. 
October 18. below 12‘5 
November 15. = 12'6 
„ 16. = 12-6 
December 26. = 12-7 
= 12T 
1863. — January 23.
