The trustees had quarrelled with the director, or the funds had given out, or the director had been shot at the head of his division, — one of those accidents had happened which will happen even in observatories which have fifteen-inch equatorials; and so the equatorial here had been left as useless as a cannon whose metal has been strained or its reputation stained in an experiment.

But a great official observatory, such as Greenwich Observatory or the Observatory at Paris, also has _transit_ instruments, or telescopes smaller than the equatorials and without the same facility of movement, but which, by a number of exquisite refinements, are more adapted to accurate measurements.

Owing to their relative fixity of position these instruments can be constructed to record the _positions_ of stars with much greater accuracy than is possible to the more general and flexible mounting of equatorials.

This instrument cannot be turned about towards every part of the sky, like the equatorials we have recently been considering.
