This star therefore ought to be narrowly watched, as it 
should seem that the two component stars are mutually 
approaching to their perihelion, or at least to their situation 
of maximum angular velocity. (H.)

When this star was measured, I was not aware that obser- 
vations of it by Mr. Herschel and myself had been commu- 
nicated to the Royal Society. Our joint result was, 
Position 29 0 2 6' sf; Distance 6". 881 ; Epoch 1823.31.
