I have been trying unsuccessfully to locate on archive.org a pdf of 

Bhāsarvajña’s Nyāyasāra, edited with autocommentary Nyāyabhūṣaṇa and editor's commentary, by Yogindrananda Svami. Varanasi 1968.

I’d be grateful if someone could share it, in particular the section on anumāna.

All best wishes,

Elisa
