揣觸（古文[耑*ㄆ]同初委反謂測度前人也江南行此音又音都果反揣量也試也北人行此音案論意字冝作㨊初委反㨊摸也通俗文捫摸曰㨊是也）。

Conjecture and touch (揣觸: in ancient script written as [耑*ㄆ]; fanqie 初委 [chū + wěi = chuǐ], meaning to measure or fathom others; this pronunciation is used in Jiangnan; another pronunciation is fanqie 都果 [dū + guǒ = duǒ], meaning to measure or to test; northerners use this pronunciation; examining the treatise's meaning, the character should properly be 㨊, fanqie 初委 [chū + wěi = chuǐ]; 㨊 means to feel or grope; the Tongsu wen says: 'To grope and feel is called 㨊', which is this).
