《明史·列传·卷四十八》
郎中林厚提出应禁止无理狡猾的诉讼、告发，以及选择理刑官、处理重犯务必凭赃物证据等四项建议，都因魏源的意见得以施行。
郎中林厚言禁刁讼、告讦及择理刑官、勘重囚务凭赃具四事，皆以源议得施行。
Lin Hou, a director of the Ministry of Justice, made four suggestions: frivolous and false lawsuits and denunciations should be forbidden, the selection of judicial officials should be conducted carefully, serious criminals should be dealt with according to evidence rather than confessions, and some judicial officials should be sent to local governments to supervise judicial work. All the suggestions were implemented thanks to Wei Yuan’s efforts.
