THE addition of a sixth satellite to the system of Jupiter marks another triumph in Prof. Perrine's employment of the modified Crossley reflector. As mentioned in a note published in “Our Astronomical Column” last week, Prof. Perrine first suspected the existence of the newly discovered body from observations made during December, 1904, but it was not until January 4 that a further observation confirmed his suspicion, and enabled him to open the new year with the announcement of this important discovery.
