 DEAR SIR WILLIAM THOMSON, 



I had intended coming to the Society, in order to make a further 

 communication with regard to the magnetic and other properties of 

 liquid oxygen, but I am confined to the Laboratory, owing to diffi- 

 culties with regard to the progress of such investigation. In the 

 meantime it may interest the Fellows to know that I have examined 

 the properties of liquid ozone in the magnetic field, and find it also 

 highly attracted. 



I hope to make a detailed communication very soon to the 

 Society. 



Yours faithfully, 



JAMES DEWAR.
