Take lead of the weight of 30 palas and rub it with the milky juice of *Calotropis gig.* and calcine it till its weight is reduced to a karsha : this residue, even if it be calcined a thousand times, will not undergo further decay (*i. e.* diminution in weight). Metallurgists call this residue derived from lead Chapala.*
