As the results of our experiments we have found that, working on ordinary plans in the wet way, we can recover an amount of gold, which is equal to, if not in all cases greater than, the quantity which the \*jamakwala\* can obtain by his expensive and protracted methods. - [Previous: v1.c18.s8.8](https://indike.org/pramana/ins.science.ray-1902.v1.c18.s8.8) - [Next: v1.c18.s8.10](https://indike.org/pramana/ins.science.ray-1902.v1.c18.s8.10) - [Up: v1.c18.s8](https://indike.org/pramana/ins.science.ray-1902.v1.c18.s8) --- Source: [https://indike.org/pramana/ins.science.ray-1902.v1.c18.s8.9](https://indike.org/pramana/ins.science.ray-1902.v1.c18.s8.9) · Pramāṇa
