The law of gases tells us that if the temperature be unaltered the pressure varies inversely as the volume, and consequently the internal pressure in the cube would in that case be increased eightfold.

Robert Stawell Ball
This deliverance or salvation is to be attained by following the eightfold path, namely, right knowledge, aspiration, speech, conduct, means of livelihood, endeavor, mindfulness and meditation.
"Buddhism and Buddhists in China"
Lewis Hodus
That eightfold increase of proportion enabled the resistance of the conductor of electricity from the generator to the burner to be increased eightfold, without any increase of percentage of loss of energy in that conductor, or decrease of percentage of development of heat in the burner; and thus enabled the area of the cross-section of that conductor to be reduced eightfold, and thus to be made with one-eighth of the amount of copper or other metal, which would be required if the reduction of diameter of the burner from one-thirty- second to one-sixty-fourth of an inch had not been made.
