It appears, therefore that the drop increases in size accord^ 
ing as the radius of the sphere increases from which the drop 
falls ; and further that the difference of drop-size brought 
about by this cause alone may easily amount to half the lar- 
gest drop-size. For dispensers of medicine this fact is as im- 
portant as that pointed out in I ; where it was shown that the
