The height of spirit of wine was exactly in the inverse 

 ratio of the distance of the plates. When the line of con- 

 tact of the {)lates was parallel to the surface of the water, 

 the fluid contained between them bent inwards as the plates 

 were raised, half way between the line of contact and the 

 surface. This curvature may be considered as the vertex of 

 a hyperbola, and the circumstance will be explained. The 

 force of attraction of a drop of spirit was observed more ac- 

 curately than that of the oil ; the inclination of the plates 

 beingis'.at 18^ inches, the elevation was 45', at Oj, 1°46', 

 at 4j, 6°, at 2^, 15°, the inclination being 10', the distance 

 18^, the elevation was 1" 30', at g~, 3" 30', at 4', 14°.
