a ton) of 1117.6 tons: the volume between the sections 11 and 
g, is found, by the Riile 11. to be = 2592 6, displacing 741 tons 
of water: the volume between the sections 12 and 11 will 
therefore displace a weight ==3 77 tons.

If any one of the adjustments determining the stability of 
a vessel should be altered, the several other conditions on 
which that power depends, will most commonly experience 
corresponding changes, the effects of which it is not easy to 
estimate, without some reference to the theory of stability. If 
the weight of the Cuflhells and contents should be diminished 
751 tons ; or rather if another vessel, constructed in all respects 
like the Cuffnells, should be loaded by 751 tons less weight, the 
following changes will take place, by which the stability is 
principally affected ; one of which is additive to, and the others 
subtractive from, the stability of the vessel. 
1st. The section of the water will be nearer to the keel by 4 
feet ; so to coincide with the horizontal section 10 instead 
/ 
of 12. 
The centre of gravity of the displaced volume will be nearer to 
the keel than before by 2.19 feet.
