When this star was observed in Blackman-street, in 1824, 
and again at this place in January of the present year, I re- 
garded it as a new double star, and registered the observa- 
tions of it as such ; a comparison however of the results with 
the measures of f Cancri, leaves no room to doubt that the 
two stars are identical. Our former measures were Position 
68° 17' sf; Distance 6 ". 241 ; Epoch 1822.14. Observations 
however which immediately follow, show that the larger 
star is itself double ; hence some suspicion as to the accuracy 
of these and of former measures will naturally arise.

Measures of AB. 
The eye-pieces adapted to the micrometer hitherto used 
with this instrument being inadequate to communicate to the 
telescope sufficient magnifying power to enable me to pro- 
cure measures of this interesting close double star, I applied 
the micrometer of the Five-feet Equatorial,* which I had for- 
tunately brought with me from England : the powers thus 
obtained are 92, 157 > 181, 327, 413, 513 and 787. As to the 
* To effect this change of micrometers, an alteration of the eye-tubes became 
necessary; on this , as on every other occasion, Mons r . Gambey supplied my wants 
so expeditiously, and at the same time so completely, that during my abode here, I 
scarcely felt the loss of Mr. Troughton. The advantage of having a first-rate 
Artist, resident within striking distance of our observatory, is almost incalculable.
