Definition
Lurgulary is a historical legal term denoting the act of casting any corrupt or poisonous substance into a water supply or body of water. The term describes a form of deliberate contamination — a willful act rather than accidental pollution — and carried criminal implications in the legal traditions from which it derives.

Why It Matters in Research
Lurgulary is a term of limited practical circulation, appearing almost exclusively in older criminal law compilations and historical treatises. Researchers encountering the word in historical materials should treat it as a period-specific label for what modern law would address under environmental protection statutes, criminal poisoning laws, or public nuisance doctrine. The term does not survive in any recognized modern legal usage, and no current statutory or common law framework employs it.
The single consistent source for this definition is Wharton — almost certainly Francis Wharton's criminal law treatises of the nineteenth century, which were widely cited by compilers of legal dictionaries in that era. Both editions of Black's Law Dictionary reproduce the same one-line definition verbatim, signaling that the term was transmitted through the dictionary tradition rather than through active judicial or legislative use. Researchers should not expect to find case law using this term as an operative legal category. Its presence in a historical document is more a marker of the source's reliance on Wharton than evidence of a living legal concept.
For research purposes, lurgulary connects to a cluster of historical offenses concerned with the corruption of common resources — wells, rivers, and waterways — which were matters of serious communal concern in pre-industrial legal systems. Modern equivalents are dispersed across multiple bodies of law: criminal statutes addressing poisoning or contamination of public water supplies, environmental law governing discharge of pollutants, and common law public nuisance claims.

Historical Dictionary Support
Both Black's Law Dictionary (1st and 2nd editions) define lurgulary identically: "Casting any corrupt or poisonous thing into the water. Wharton." The citation to Wharton is the sole attributed source in both editions, and neither dictionary elaborates on the term's origin, its jurisdictional home, or its procedural context. This pattern — a single sentence definition sourced entirely to one treatise writer — suggests the editors included it as a term of historical or comparative interest rather than as a word in active legal circulation at the time of publication.
The absence of the term from later editions and from competing historical dictionaries such as Bouvier's reinforces the impression that lurgulary occupied the margins of formal legal vocabulary even in the nineteenth century. No independent judicial definition has been identified. Researchers should treat both dictionary entries as derivative of Wharton and should consult Wharton's criminal law treatises directly if the term's original context matters to their inquiry.

Jurisdictional Note
No jurisdiction has been identified that used lurgulary as a statutory or common law term of art in reported decisions. The term appears to be a doctrinal curiosity absorbed into American legal dictionaries from English or general criminal law scholarship rather than a term operative in any specific court system.
