Attached is page 247-248 of Henry Raper's The Practice of Navigation and Nautical Astronomy, from 1840, describing how to utilize Jupiter's satellites. And what to expect when it comes to accuracy. In the 1906 edition there is added a sentence "The first satellite is preferable to the others on account of the greater rapidity of its motion".
