From this table is deduced the following Table III, which 
shows gt in seconds and the corresponding drop-weights in 
grammes ; the latter being the mean of the results in Table 
II. gt is got by dividing the time lapses of Table II by the 
number of drops.

From Table III, to which Table I may be joined as a con- 
tinuation, it at once appears that, on the whole, for oil, 
within the above limits, the weight or size of a drop dimi- 
nishes as its grow r th-time increases. Further it seems that 
between the rates gt. = .57 a minimum occurs : that is, in- 
stead of there being a continuous diminution in the weight as 
the growth time increases, there is at first a diminution, then 
an increase and finally a continuous diminution : so that 
%> 
drops of the rate gt. — .51 have the same size as those of the 
rate gt. — .64. In order to establish more precisely the posi- 
tion of this minimum and the general relation between rate 
and size, a more minute division of the time must be made 
and the table must be more extended. From this short Table 
however may be gathered how extremely sensitive the size of 
the drop is in regard to the time wdiich it takes to form.
