A Moon Suit isn't a Mars Suit isn't a Venus Suit isn't a Triton Suit isn't a.... Carry it on from there. Number Three was insulated against a frigid but relatively non-corrosive atmosphere.
Then somebody found a new use for gold by inventing a process by which it could be hardened and tempered, assuming a wonderful toughness and elasticity without losing its non-corrosive property, and in this form it rapidly took the place of steel. In the mean time every effort was made to bolster up credit. Endless were the attempts to find a substitute for gold.
The absolute freedom of all moving parts of the spraying mechanism should be one of the tester's first assurances. To facilitate this, it is customary to construct the parts, with the exception of the springs, of brass or some other non-corrosive metal. The spraying cone must be thoroughly clean in every channel, to insure a well-distributed stream of water.
Spectacle frames of non-corrosive white metal, not steel, are the proper sort. To clean your guns you must supply plenty of oil, and then some more.
