No one knows who devised the cross-references in William Hawkins’ 1795 Treatise of the Pleas of the Crown, but he was either very wry or very cynical:

Cattle see Clergy.
Chastity see Homicide.
Coin see High Treason.
Convicts see Clergy.
Death see Appeal.
Election see Bribery.
Fear see Robbery.
Footway see Nuisance.
Honour see Constable.
Incapacity see Officers.
King see Treason.
Knaves see Words.
Letters see Libel.
London see Outlawry.
Shop see Burglary.
Threats see Words.
Westminster Hall see Contempt and Lie.

“A plain, unlettered man is led to suspect that the writer of the volume and the writer of the index are playing at cross purposes,” noted the Monthly Magazine. Perhaps they were.
