Halaman 61 - Small variations from this value are of no significance, although the small value pertaining to the high pressure and temperature may indicate some variation in this direction. A complete investigation of this characteristic of the gas would include many more determinations than these which are recorded, but it is not the purpose of the writer at this time to fix numerical values for extreme conditions. Enough is given to establish the fact that the exponent has a value markedly below the ratio of...

Halaman 9 - Substances resembling petroleum are produced by the decomposition of animal remains. 5. Fraas observed exudations of petroleum from a coral reef on the shores of the Red Sea, where it could only be of animal origin. In summing up the evidence as to origin, Hofer expresses the belief that petroleum is of animal origin and has been formed without the action of excessive heat, and observes that it is found in all strata in which animal remains have been discovered. He considers that the oil is the primary,...

These engines are considered more hazardous than stationary engines having separate underground storage tanks, and should not be used as a substitute for stationary engines. Where used, their hazards should be recognized by the inspection department...
