Wedge-shaped bricks were used to make these curves, and after they were laid in position their inner surfaces were carefully rubbed smooth; indeed, much more care seems to have been taken over the drains than with some of the buildings above ground. - [Previous: c5.51](https://indike.org/pramana/ins.epigraphy.mackay-1935.c5.51) - [Next: c5.53](https://indike.org/pramana/ins.epigraphy.mackay-1935.c5.53) - [Up: c5](https://indike.org/pramana/ins.epigraphy.mackay-1935.c5) --- Source: [https://indike.org/pramana/ins.epigraphy.mackay-1935.c5.52](https://indike.org/pramana/ins.epigraphy.mackay-1935.c5.52) · Pramāṇa
