| The solid, yellow, easily fusible and combustible substance well known by the name of sulphur, is an element in almost the pure state. It occurs fairly widely distributed in nature in the form of elongated octahedral crystals of a honey-yellow colour. The occurrence of sulphur is especially connected with volcanic phenomena. The whole consumption of sulphur in Europe has for a long time been supplied by Sicily. At the present day large quantities of free sulphur are also obtained from compounds of sulphur which are exceedingly abundant in nature. |
