and, therefore, I think the bill, so far as the discovery is con-
cerned, cannot be maintained, and that the demurrer must be
ruled good.

In strictness, the allowing a demurrer to the whole bill, puts
it out of court, and no subsequent proceeding can be taken in
the cause; yet there are cases in which the court has afterwards

opportunity of amending it, if they think proper.

It is, thereupon, this 12th day of November, in the year 1847,
adjudged and ordered, that the demurrer to the discovery of the
defendant's title, sought by this bill, be, and the same is, hereby,
ruled good, and that the defendants recover from the plaintiffs
their costs to be taxed by the Register; but this bill is retained
with liberty to amend, as the plaintiffs may be advised.

[No appeal was taken from this order.]

bear from the repetition of the acts which impeded the enjoyments of the
rights and the discharge of the duties on the part of the professors. HELD—

That an injunction of this description cannot be regarded as going beyond the
