Series II exhibits the splash of a drop of milk '502 centim. in 

 diameter, falling from a height of 43 centims. into water. All the 

 characteristics of the last splash are here more strongly marked. The 

 hollow is deeper and wider, the drop descending farther below the 

 surface before it is completely covered. Rays, whose origin will be 

 explained hereafter, are shot out symmetrically from the centre. Their 

 number seemed to vary a good deal, and I have made no attempt to 

 select drawings which are in agreement in this respect. It will be 

 understood that these rays contain little or none of the liquid of the 

 drop, which remains collected together at the centre. 



The drop, after being completely covered and lost to sight (figs. 3 

 and 4), emerges as before (figs. 5 and 6), but the energy of the impact, 

 instead of being expended in raising the same amount of liquid to a 

 greater height, is now spent in lifting a much thicker adherent column 

 to about the same height. 



There was sometimes noticed, as is seen in fig. 9, a tendency in the 

 water to flow up past the milk, which, still comparatively unmixed 

 with water, forms the top of the emergent column. 



The greater relative thickness of this column prevents it splitting, 

 and figs. 10 and 11 show it descending below the surface to form the 

 hollow of fig. 12, up the sides of which an annular film of milk is 

 carried (figs. 12 and 13), having been detached from the central mass,
