By the seventh day the young snakes turn dark; in a fortnight (or twenty days, according to another account) the teeth come out. The poison is formed in the fangs (दंष्ट्रासु) in three weeks, and becomes deadly in the twenty-fifth night. In six months \*Nâgas\* shed the skin (कञ्चुक). - [Previous: c8.t4.1](https://indike.org/pramana/ins.science.seal-1915.c8.t4.1) - [Next: c8.t4.3](https://indike.org/pramana/ins.science.seal-1915.c8.t4.3) - [Up: c8.t4](https://indike.org/pramana/ins.science.seal-1915.c8.t4) --- Source: [https://indike.org/pramana/ins.science.seal-1915.c8.t4.2](https://indike.org/pramana/ins.science.seal-1915.c8.t4.2) · Pramāṇa
