As the first glimpse of a new star is caught bj the eye of
the astronomer while directing his vision to a different point
of spa«e, and disappears when steadfastly gazed at, only to
have its position and figure ultimately ascertained by the em-
ployment of more penetrative powers, so the fiist scintillations
