9. "Rasa-ratna-samuchchaya" (treatise on mercury and metals) is a comprehensive work of the fourteenth century. It embodies practically the whole chemical, mineralogical, and metallurgical knowledge of the Hindus developed through the ages. Like the "Brihat Samhita" (sixth century A.D.) by Varaha-mihira, it is a scientific encyclopædia. It is specially remarkable for its section on the laboratory, directions for experiments, and description of apparatus.
