 CHINI'S Experiments were published in Gilbert's Annalen 

 der PhysiJc, in 1813 ; see also Annals of Philosophy, ii. 390, 

 where PLAYFAIE gives an account of the success of these 

 experiments in the hands of M. CAEPE. In Ann. of Phil., 

 iv. 228, they are, however, denied by other authors.

 paper Sir William Snow Harris has arrived at the conclusion 

 that magnetism induced by the sun's rays does not occur in a 

 vacuum. " The influence of the sun's rays," says the author, 

 " on a magnet oscillating in air, is to reduce more rapidly the
