Five samples, procured from the market and prepared according to the indigenous method, when exhausted with water gave in the filtrate only faint brown coloration with sulphuretted hydrogen. It is thus evident that these were all free from corrosive sublimate.
v1.c22.s3.3
Dutt, we are afraid, derived much of his information on chemical subjects from hearsay. By "subliming the black sulphide of mercury with common salt," we got, as we expected, merely cinnabar. The sodium chloride was simply left behind. It is to be regretted that the new edition of Dutt's valuable work, which claims to be "revised," reproduces all the glaring errors of the first.
