which descends to be torn again, this time centrally, into a vortex 

 ring. 



On increasing the height of fall to 1 metre and retaining the same 

 size of drop, no great change in the nature of the splash takes place, 

 but the emergent column is rather higher and thinner, and shows a 

 tendency to split into drops. It does not, however, succeed in doing 

 so, and a well-defined vortex is produced as before. But on letting 

 fall into water a drop of twice the volume ('625 centim. in diameter) 

 from the height of 133 centims. the splash of Series III is obtained, 

 which is beginning to assume quite a different character. 



Seeies III.
