(Antiq. Hindu Med.) There is no necessity for looking upon hīrákasa as a hybrid term, seeing that it occurs in the present work in which Mahommedan influence is nowhere traceable. - [Previous: v2.c32.s8.t1.15](https://indike.org/pramana/ins.science.ray-1902.v2.c32.s8.t1.15) - [Next: v2.c32.s8.t1.17](https://indike.org/pramana/ins.science.ray-1902.v2.c32.s8.t1.17) - [Up: v2.c32.s8.t1](https://indike.org/pramana/ins.science.ray-1902.v2.c32.s8.t1) --- Source: [https://indike.org/pramana/ins.science.ray-1902.v2.c32.s8.t1.16](https://indike.org/pramana/ins.science.ray-1902.v2.c32.s8.t1.16) · Pramāṇa
