CHINI’S Experiments were published in Gilbert’s Annalen

where PLAYFAIR gives an account of the success of these 
experiments in the hands of M. Carpr. In Ann. of Phil.,

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
