it was also proved that in the specimens studied, the magnetic 

 force and the induction were proportional for forces between 5*0 

 ai<d 0*9 C.G.S. units. 



Since 1 the publication of the above results I have (through the 

 good offices of Professor Threlfall), received from Mr. C. S. 

 Wilkinson of the New South Wales Geological Survey, specimens 

 of a number of Australian basalts. The same apparatus was used. 

 r J he liquids were tested by means of some of the specimens 

 previously studied and were found to be unaltered. The experi- 

 ments were made by Messrs. J. W. Pickles, and W. E. Harrison, 

 students in the Physical Laboratory of the Royal College of 

 Science, London. The following table contains the results. The 

 susceptibilities are expressed in C.G.S. units.
