v1.c11.t12.1

“Make two iron crucibles each 12 digits in length, the one with a narrow orifice containing sulphur is inserted into the other holding mercury ; below the mercury is placed water [in a separate vessel]. The mercury and the sulphur should be carefully moistened in garlic juice, which has been filtered through a cloth. The apparatus is now lodged in an earthen pot and another placed over it, the rims being luted with cloth previously smeared with earth * * now cow-dung fire is urged. After continuing heating for three days the apparatus is taken out." [This description, in almost identical recension, occurs in R. R. S. under the name of जारणयन्त्रम्. The language is faulty and the meaning not very clear.]
