2.36

[(餐-食)-又+臭]物（昌呪反考聲云敗惡氣也說文云禽走而知其跡者犬也自者古鼻也從自從犬或從反作殠經文從死作臰非也竝無此字）。

Putrid thing ([(餐-食)-又+臭]物: [the upper character is] chang + zhou fan. The Kaosheng says: spoiled, foul vapor. The Shuowen jiezi says: a hound is what knows tracks when beasts flee; zi (自) is the ancient character for nose; it takes zi and dog (犬). Some write it with fan as 殠. The sūtra text writes it with death (死) as 臰, which is incorrect; that character does not exist at all).
