SERIES V. 



The Splash of a Drop, followed in detail by Instantaneous Illumination — 



continued. 



The Size of Drop and Height of Fall are the same as before, but the hollow shell 

 (see figs. 4 and 5 of the previous Series) does not succeed in opening, but is left as a 

 bubble on the surface. This explains the formation of bubbles when big raindrops fall 

 into a pool of water.
