3. When a person is charged with a crime, he is sometimes induced to make confessions by the flattery of hope, or the torture of fear. When such confessions are made in consequence of promises or threats by a person in authority, they cannot be received in evidence. In England a distinction has been made between temporal and spiritual inducements; confessions made under the former are not receivable in evidence, while the latter may be admitted.

INDUCEMENT, pleading. The statement of matter which is introductory to the principal subject of the declaration or plea, &c., but which is necessary to explain and elucidate it; such matter as is not introductory to or necessary to elucidate the substance or gist of the declaration or plea, &c. nor is collaterally applicable to it, not being inducement but surplusage. Inducement or conveyance, which. are synonymous terms, is in the nature of a preamble to an act of assembly, and leads to the Principal subject of the declaration or plea, &c. the same as that does to the purview or providing clause of the act. For instance, in an action for a nuisance to property in the possession of the plaintiff, the circumstance of his being possessed of the property should be stated as inducement, or byway of introduction to the mention of the nuisance.
