[47] In making this suggestion, the author is well aware that
Ephemerides of the four chief asteroids have been given annually in the
Greenwich Nautical Almanac; but for the object proposed they are utterly
useless. Will any astronomer contend that these Ephemerides are true to
ten seconds of arc? If not, they are useless for the purpose suggested
above, and the theory wants revision. And it is evident that any
objection against its practicability, founded on the uncertainty of the
number of the asteroids themselves, as has already been urged in answer
to this suggestion, is an evidence that the objector weighed the subject
in the scales of his imagination only.
