It will be seen that the residt of direct exposure to the air a lapid loss of 'sulphide' sidphnr. At the end of fourteen to twenty-three days no 'sulphide' sulphur remained except ill the case of .sam|)le (f), and a trace in sample (b). The |ioint to be emphasized from the foregoing results is that :/mif can- sliutdd hr exercised in xturin;/ liver of sulphur, f sulplnirettcd liyilrogen, decompositinii has ])roceeded .so far that nul|)liide' sulphur remains.
