The relation exhibited in this table supports the supposition 
that the size of the drop varies inversely as some function of 
the figure bounded below by a circular horizontal tangent 
plane of coifttant diameter, (less than that of the sphere), la- 
terally, by a cylinder of vertical axis' standing on the tangent 
plane and cutting the sphere, and above by the convex sur- 
face of the sphere. Fig. IV. 
As the diameter of the sphere still further diminishes, the 
size of the drop is limited by the possible size of its base : un- 
till finally the sphere is completely included in the drop. 
It would be interesting, but it would take us too far to 
consider the various cases of liquids dropping from cones ed- 
ges, solid angles, cylinders, rings &c. We must content our- 
selves, in this direction with the fact that the size of a drop is 
greater the more nearly plane is the surface from which the 
dropping takes place. If it were possible for a drop to fall 
from a concave surface we would anticipate a still further in- 
crease in its size. 
The relation between drop-size and curvature may be more 
strikingly shown by arranging the spheres one above the other 
in the order of magnitude Fig. Y. Each sphere receives the 
drops from the higher one. The quantity of water which 
drops in a given time, is the same for each sphere. Hence in 
every case the number of drops is inversely as their size, So
