Hence in none of these cases is the drop size of one li- 
quid through another equal to the drop size of the second 
through the first. We get the general law that. That if a li- 
quid X has a larger drop she than the liquid Y in the liquid 
Z then the liquid Z has a larger drop size in X than it has in 
Y. Further if a, liquid X has a larger drop size than a liquid 
Y in air; then the drop size of X through Y is larger than the 
drop size or Y through X. Further if the drop size of X be 
greater than the drop size of Y and the drop size of Y greater 
than the drop sizes of Z, then the ratio between the drop 
sizes of X in any mixture of Y and Z and the drop size of 
that mixture of Y and Z through X Is greatest when the ratio 
between Y and Z is unity. 
Further comparing the drop -sizes of Table XVIII with one 
another or all with B w wc get :
