 It may be regretted that St. Raymond did not have recourse to the original documents themselves, of which a large number must have been at his disposal.The summaries ("summaria") that precede the chapters are the work of the canonists, and may assist in the elucidation of the text.The "partes decisae" are sometimes of like use, but never when these parts were designedly omitted from a desire to extinguish their legal force or because they contain decisions irreconcilable with the actual text of the law.
