persons, with their instruments, would have occu-

called Antechamber and King's Chamber—then,
of course, not walled in (or the walls would have
obstructed the view along the gallery). These
persons themselves would not obstruct the view,

Or they might be close to the mouth of the gallery
at its sides, without obstructing the view.
But now, notice that if the place they thus

the region in or near which all the observations of
the heavenly host in culmination had been made)

stationed at certain special points on this horizontal
top, to observe certain important horizontal lines,
viz. the lines directed to the cardinal points and to
points midway between these. An observer who
