M. Sttuve’s Observations on Double Stars. 
m 
7^. y Dolphin. R. Asc. 20^ 88'. N. DecL 15° ^9^. 
4!th-5th and 5th-6th Mag. 
The difference of R. Asc. is — and the angle of posi- 
tion 4° 42' N. Free. ; the distance 12".54, and the difference of 
declination + 1".08. There seems to be no reason to suppose 
along with Sir W* Herschel that one of these stars has a proper 
motion. 
78. f 1, Little Horse. R. Asc. 20^ 5(y. N. Decl. 8° 36'. 
5th and 7th Mag. 
The difference in R. Asc. in 1819 is -f- 0".746 ; the angle of 
position 10° 15' N. Foil. ; and hence the distance is 11'*'.85. Sir 
W. Herschel found the distance 0".8795 and the angle of posi- 
tion 6° N. Foil. 
74. § Little Horse. R. Asc. 21^ 6'. N. Decl. 9" IT. 
The small star is very difficult to be seen, and M. Struve has 
not yet been able to see it with his meridian telescope. He es- 
timates the angle of position to be about 40° N. Foil. Sir W. 
Herschel found it to be 12° N. Foil, in 1781. It has therefore 
undergone a great change. 
75. Cepheus* R. Asc. 21^ 26'. N. Decl. 69° 46'. 
8d and 9th Mag. 
In 1818 and 1819 the difference of R. Asc. was 2''''. 409 ; 
and the angle of position in 1820 was 20° 6' S. Free. Hence the 
distance will be 18".81. The angle of position given by Sir W. 
Herschel is 5° less than that of M. Struve. 
76. fc. Cepheus. R. Asc. 21*^ 49'. N. Decl. 55° 44'. 
6th and 11th Mag. 
Sir W. Herschel observed that this star was composed of two 
equal ones, at a distance of 21".05, with an angle of position of 
77° 48' S. Free. M. Struve observed this star very often in 1819, 
but has never succeeded in discovering its companion. He saw 
--a star of the 11th magnitude, but it was distant 7". 49 in time 
from the other.
