Him has left the sphere at an earlier stage, and has more nearly the configuration 

 observable in a rough splash. In Series XVI., of which tigs. I, 2, and 3 are reproduced 

 in Plate 3, the height of fall was 100 centims., and the change was still more 

 marked. No air is taken down by this splash. 



In order to avoid the necessity of a somewhat inconveniently great height of fall, 

 which would have l>een imposed by the further use of water as the liquid, we 

 employed Alexandra oil for watching below the surface the beginning of the process 

 by which the sphere takes down air hi its wake. Thus Series XVI I., Sheet 5, here 

 reproduced in the text, shows the splash of a polished nickdled-steel sphere

> The photographs (unt,,i innately not the reproductions here given) Mh of this and of our previous 

 paper illustrate incidentally the great rapidity with which fine jets undergo division into drops, which, 

 however, as Lord RAYUicfH has explained (' Roy. Soc. Proc.,' vol. 29, 1879, p. 86, oh the Capillary 

 Phenomena of Jets), need cans* no surprise, since the time of complete segmentation will vary inversely 

 us the 3 2 power of the diameter if viscosity does not hinder.
