Preliminary experiments having shown that the size of a 
drop is greatly affected by the rate at which the dropping 
takes place, that is, by the time occupied by the drop in its 
formation, the following experiments were performed to estab- 
lish the connexion between the two. 
It may be here remarked that, with some liquids, a conti- 
nuous stream of liquid by no means implies a faster delivery 
of it than may be achieved by a succession of drops. On the 
contrary, just as by walking more rapid progress may be made 
than by running, so may dropping deliver more liquid than 
passes in a stream. A uniformly rapid series of drops may 
be converted into a stream and reconverted into drops under 
certain restrictions, at pleasure. We shall return to this fact 
in the sequel.
