But the last such work to which reference should be made here is the Vyavahāraratna⁴⁹ written by Bhānunātha⁵⁰ in Mithilā in 1872. This tradition, like that of genethlialogy, is still very much alive. - [Previous: c8.65](https://indike.org/pramana/ins.science.pingree-1981.c8.65) - [Next: c8.67](https://indike.org/pramana/ins.science.pingree-1981.c8.67) - [Up: c8](https://indike.org/pramana/ins.science.pingree-1981.c8) --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c8.66](https://indike.org/pramana/ins.science.pingree-1981.c8.66) · Pramāṇa
