Parallel. We have already adverted to the then young Struve's 
_ Measurement of the same remarkable star, and to the effect which 
it had on the direction of his energies: this, however, was but a 
Single and isolated result, and it was not until some years ater 
Ramely, in 1819, that the record of measured angles of
