to loosely cemented and irregular samples; it is also one of the best available 

 methods with which the porosity of small fragments or drill cuttings can be 

 obtained. Displacement is a more rapid procedure than submergence, and ir- 

 regular samples can be measured, but high porosity samples have a tendency to 

 absorb enough mercury to reduce materially the pore space for subsequent pore-
