He put on the air of a subordinate who obeys without reasoning.
This time he obeys.
And this is fulfilled when he obeys the commands of law and the true order; when he tends his cattle and fields, in contrast with the lawless and predatory nomad (Dahae); when he wars on all harmful and evil creatures, and on the devilworshippers; when he keeps free from pollution the pure creations of Ahuramazdauire foremost, but also earth and water; and, above all, when he practises the Good and True in thought, word and work.
But if the epithet is intended to designate an animal that takes an interest in its rider so far as a beast can, that in some way understands his intentions, or shares them in a subordinate fashion, that obeys from a sort of submissive or halffellow-feeling' with his master, like the horse or elephant, then I say that the camel is by no means docile - very much the contrary.
The equation of energy is dQ=dE+pdv, (17) expressing that the total energy dQ is used partly in increasing the internal energy of the gas, and partly in expanding the gas against the pressure p. If we take p = RNT/v from equation (14) and substitute for E from equation (16), this last equation becomes dQ 2 (n +3)RNdT +RNTdv (18) which may be taken as the general equation of calorimetry, for a gas which accurately obeys equation (14).
