Michael Faraday, his Life and Works, 169 
baillif’s experiment, which I had witnessed at the time, He 
accepted my reclamation in the most amicable manner, and at 
once, with his usual good faith, recognized the priority of Mr. 
, Lebaillif with regard to bismuth and antimony 
In the numerous researches which Faraday devoted (from 
1845 to 1855) to diamagnetism and at the same time to mag 
netism, there are some important points which I must indicate, 
He discovered the remarkable influence exerted upon this kind 
of properties by the molecular constitution ‘of bodies,.and es- 
pecially by crystallization. He showed, for example, that a 
crystallized lamina of bismuth or antimony can place itself 
to the direction of its cleavage. He endeavored to ee 
the force which comes into play in facts of this order, which 
taken b oxygen in the composition of page, cag he at- 
tempted to explain, by the magnetic a igs of gas CO’ 
bined with variations of temperature, the phenomenon of the 
diurnal variations of the magnetic needle which he traced over 
all parts of the surtace of the globe. It is impossible for us 
Hot to regret a little the considerable time which he devoted to 
ti 
that it is not in the action of the atmosphere, but mu 
investigation, especially as it appears to us. vay eae
