ON THE ELECTRICAL PROPERTIES OF PURE SULPHUR. 
Note added April 1 , 1895. 
Experiments made March and April, 1894. 
A possible explanation of the very divergent values of K, as exhibited by different 
modifications of sulphur, may be sought in the corresponding variations of density. 
To test this point, an examination was made of the density of the sulphur 
employed in the experiments for K by weighing. The accuracy of the determination 
of density extends to the third figure at least. 
The following table will show that the variation of specific inductive capacity is 
not to be explained by supposing that it is merely proportional to density.

the Forms of Sulphur.
