Dear Colleagues, 
I am looking for two papers published in Vidya – The Journal of Gujarat University
Solomon, Esther A.: “Aviddhakarṇa: a forgotten Naiyāyika”, Vidya – The Journal of Gujarat University 13,1 (1970) 18–40.
Solomon, Esther A.: “A further note on Aviddhakarṇa”, Vidya – The Journal of Gujarat University 14,2 (1971) 19–24.
Perhaps someone has them? I'd greatly appreciate your help. 
Best regards, 
Piotr Balcerowicz
