Debt on a penal bond, of which profert is made in the declaration. The defendants craved oyer of the bond, and it was granted. -They then craved oyer of the condition ofthe bond, but this was denied by the Court below.

Fie was denied information to which the law entitled him, and without which it was not to be expected that he could make his defence.

The judgment is reversed’, and the proceedings subsequent to the demand of oyer of the condition of the bond are set aside, with costs. Cause remande.d for further proceedings.
