Applying the Rule hi. to these areas, and 
making the common distance between them 
= r = 5 feet, the solid contents between the 
first horizontal section and the keel is found to 
beS-j-2P-|-3Q x = : 871.0 feet.

tions 12 and 1

Total contents of the volume immersed 
between the first and thirty-fourth 
vertical section - 119384.0 
Let this volume be represented by the letter V. 
By the preceding computations, the line PQ 
= b was found = 27.32, and the volume 
immersed by the vessel's inclination, or A = 
118509. From these determinations, the line 
ET is inferred; for, according to the general 
theorem, 
as V : A : : b : ET or 
119384 18509 27.32 4.23 
wherefore ET = 4.23. 
* The rules here employed for measuring the volume displaced, 
cannot be applied to the irregular parts of the vessel, adjacent to< 
the head and stern, without constructing and measuring the or-
