The first isolated nebula which was observed and recognized 

 by the telescope as wholly starless and as an object of special 

 nature was the nebula near v Andromedee, which, like that 

 last mentioned, is also visible to the naked eye. Simon Marina 

 (Mayer of Gunzenhausen, in Franconia), originally a musician, 

 and subsequently Court mathematician of one of the Mar- 

 graves of Colmbach, the same person who saw the satellites 

 of Jupiter nine days earlier than Galileo, 7 has also the merit

 voured to refer the difference in the days of discovery (29th 

 of December, 1609, and 7th of January, 1610,) to a differ- 

 ence in the calendar, maintained that he had seen the satel- 

 lites of Jupiter one day earlier than Marius, and even allowed 

 himself to be so far carried away by his indignation at " the 

 falsehood of the heretical impostor of Gutzenhausen " ("luaia 

 del impostor e erctico Guntzenhusano") as to declare his belief 

 k% that very probably the heretic, Simon Marius, never observed 

 the Medicean planets," (" che molto probabilmente il eretico, 

 Simon Mario, non ha osservato giammaii Pianeti Medicei")

 237; and Nelli, Vita e Commercio letterario di Galilei, 1793, 

 vol. i. pp. 240-246. The "heretic" had nevertheless 

 expressed himself very pacifically and modestly in reference 

 to the extent of merit due to his discovery. " I simply 

 affirm," says Simon Marius, in the preface to the Mundus 

 Jouialis, "La3c sidera (Brandenburgica) a nullo mortalium 

 mihi ulla ratione commonstrata, sed propria iiidaginc sub 

 ipsissimum fere tempus, vel aliquanto citius quo Galila3us in
