been used together. The interval between them is a full magnitude, and it was in fact underestimated in steps. l h e step in these three estimates is about twice as large as in the others. This difference will however not affect the re- sults by formula 11.
If the number of steps in these and the former ob- servations of the Nova appear larger than what high authori- ties have recommended, it is well to observe that according to Table 11:
Thus the average step here employed is about one half of Schonfeld's step and somewhat less than one half of Argelander's. Bot these observers not unfrequently used half-steps, which taken as the unit measure would make their records similar to those published here. By warning against more than 4 steps they meant to say that an inter- val estimated in steps should be less than half a magnitude.
