SULPHUR 



(Sulphur = S) 



The sulphur ordinarily used in the laboratory is of 

 two kinds, roll sulphur and flowers of sulphur. The 

 difference is merely a physical one and- is due to the 

 method by which each is prepared from the element 

 as it is found in nature. 



Occurrence. Sulphur is found both in the free state 

 and in combination with other elements, though com- 

 mercial sulphur is prepared chiefly from sulphur in 

 the free state. It is found very widely distributed, 

 being usually associated with volcanic regions. The 

 largest deposits occur in Sicily, Texas, and Louisiana, 

 with Japan, Mexico, and California adding to the 

 world's supply. In Yellowstone Park it is found in 

 sulphur springs. It is also found in many vegetables 

 and in the yolk of eggs, and it forms no inconsiderable

 being present in the body of a man of ordinary 

 size. Sicily formerly held first rank in the amount 

 of sulphur annually given to the markets of our coun-

 element throughout that region and to the cheapness
