Lead thus prepared is a gritty powder of a greyish red colour. Chemically it is an impure carbonate of lead. Its properties are said to be similar to those of tin. It is seldom used internally except as a component of compound medicines containing a number of other metals. A probe made of lead is preferred for applying collyria to the eyelids. - [Previous: c4.s13.3](https://indike.org/pramana/ins.science.dutt-1877.c4.s13.3) - [Next: c4.s13.5](https://indike.org/pramana/ins.science.dutt-1877.c4.s13.5) - [Up: c4.s13](https://indike.org/pramana/ins.science.dutt-1877.c4.s13) --- Source: [https://indike.org/pramana/ins.science.dutt-1877.c4.s13.4](https://indike.org/pramana/ins.science.dutt-1877.c4.s13.4) · Pramāṇa
