"Il s'agit de la fabrication de l'oxyde de mercure préparé \*per se\*, c'est-à-dire sans addition d'aucun corps étranger." \*Ibid\*, p. 154 - [Previous: v1.c20.11](https://indike.org/pramana/ins.science.ray-1902.v1.c20.11) - [Next: v1.c21.1](https://indike.org/pramana/ins.science.ray-1902.v1.c21.1) - [Up: v1.c20](https://indike.org/pramana/ins.science.ray-1902.v1.c20) ## Cites (1) - [Rasārṇava](https://indike.org/pramana/in.med.rasa.siddha.rasarnava) — Sanskrit --- Source: [https://indike.org/pramana/ins.science.ray-1902.v1.c20.12](https://indike.org/pramana/ins.science.ray-1902.v1.c20.12) · Pramāṇa
