fcbe equator towards the poles, and from the poles towards 

 the equator. By their movemtnls and combinations they 

 produce all the phaenomena of electricity, galvanism, and 

 magntfisni. 



" When they are rapidly caught by friction machines, as 

 they are called ; and when the movement given to them 

 does not allow them time enough to separate from edjch 

 other, they show themselves in the stale of mixture ; they 

 produce the phasnomena qf ordinary or mixed electricity. 



" When they are caught by the Galvanic apparatus they 

 are separated from each other ; each is projected towards 

 one of the two extremities of the apparatus. They then 

 produce all the phaenomena of galvanism. They prodiu:e, 

 among other phaenomena, their own reduction into per- 

 ceptible gases when we receive them in a vessel full of 

 water, where, by the effect of the pressure of the liquid, 

 they are constrained to condense : the oxygenated fluid re- 

 sumes the state of oxygen gas; the hydrogenated fluid re- 

 sumes that of hydrogen gas. As in friction machines the 

 two fluids are always confounded, the condensation of these 

 two fluids by the pressure of water produces a mixture of 

 oxygen and hydrogen gases. 



" All living beings are electrical apparatuses, in the inte- 

 rior of which sometimes the phaenomena of mixed electricity 

 take place, sometimes the phoeuomena of doubled electri- 

 city, or galvanism. 



*' When the two electrical fluids, abandoned to their na- 

 tural course, meet with bodies which have an equal affinity 

 for one and the other, they give to these bodies, by pene- 

 trating incessantly into them, the magnetical constitution. It 

 is in this manner they produce, by the help of these bodies, 

 all tlie phaenomena of magnetism. 



" The oxygenated fluid is the principle of acid composi- 

 tions ; the hydrogenated fluid is the principle of alkaline 

 compositions. Those two fluids, by penetrating and press- 

 ing continually into the heart of the sea, arc partly com- 

 bined with aqueous molecules ; and thus form on the one 

 hand muriatic acid, and on the other hand soda. 'I'hese 

 two compositions are also combined by ihf- ctl'ect of tlie
