of gt. and the ordinates the corresponding weights, there is 
no apparent asymptote parallel to the axis of X. The curve 
presents however in its course two secondary maxima and 
minima. 
Secondary Maxima. Secondary Minima. 
(1) gt. = .450 gt. = .433 
Although at these minima the drops are less than at the 
immediately succeeding rates, yet the quantity of liquid pass- 
ed in a given time is, at every rate of dropping, greater than 
the quantity passed at a slower rate in the same time. The 
decrease of rate more than counterbalances the temporary in- 
crease in the drop size. This is seen on comparing the num- 
bers of column III with one another. They are found to de- 
crease continuously, though by no means uniformly, as the 
rate of dropping decreases. 
The second maximum (at gt —. 500 and gt—. 517) is ill re- 
markable connexion with the rate at which a series of drops 
may be converted into a continuous stream. At the rates of 
dropping from gt. — .2>?>2> to gt—.§Y7 inclusive the drops may 
be converted into a permanent stream by pouring a little of 
the liquid upon the sphere as the drops are falling from it. 
A stream is thus established which remains for any length of 
time if it be protected from all currents of air and vibration 
At the rate gt — . 519 the stream maybe established by the 
same means for a few seconds (about 30”) ; but the continu- 
ous part inevitably begins to palpitate, becoming alternately 
longer and shorter, thinner and thicker, until at length it 
draws up and is converted into drops. At the immediately 
succeeding slower rates of dropping, the same effect follows, 
but in each case in a shorter time. So that the slowest rate 
of dropping which may be converted into permanent running 
coincides with that rate which gives the second maximum size 
of drops (gt= .500 and .517) . The appearance of a drop-con- 
vertible stream is peculiar, the narrowing which it undergoes
