 *Coulomb on the law of the magnetic and 



electric forces. A. P. 1785. 



Finds, that they vary as the squares of the distances in- 

 versely. A needle is urged by a constant force in the direc- 

 tion of the quiescent position. 



Coulomb's seventh memoir. A. P. 1789. 455. 

 Roz. XLIII. 247. 



Particular consideration of the separation of a magnet. 



Coulomb on the ft)rces of needles. M. Inst. 

 III. 176. Ph.M.XI. 18.3. 



When the form is similar, the force is as the weight. 

 Coulomb supposes the existence of two magnetic fluids, 

 which are only displaced in each molecule.
