Early in 1855 he conducted large-scale experiments at Javel in a factory lent him for the purpose, where he produced sufficient to show at the French Exhibition of 1855.
The volume actually weighed was 163 c.c. Subsequently large-scale operations with the same apparatus as had been used for the principal gases gave an almost identical result (19.940) for argon prepared with oxygen.
He has left dated notes and drawings made at most of the stations we have named, besides a set of six large-scale maps drawn minutely with his own hand, and including nearly the whole territory of the Maremma, Tuscany and Umbria between the Apennines and the Tyrrhene Sea.
Taken together, this makes the financial consequences of large-scale war untenable.
Yet tons of caustic soda are fused daily in chemical works in iron pots without thereby suffering contamination, which seems to show that (clean) iron, like gold and silver, is attacked only by the joint action of fused alkali and air, the influence of the latter being of course minimized in large-scale operations.
On large-scale maps it is necessary to show two coast-lines, one for the highest, the other for the lowest tide; but in small-scale maps a single line is usually wider than is required to Coast- represent the whole breadth of the inter-tidal zone.
If NATO is responsible for the bulk of the world's military spending and NATO no longer has the stomach for full-on war with modern states, then large-scale war seems less likely.
In 1967, Colin Clark estimated that the minimum space necessary to feed a person was 27 square kilometers, a then-optimistic figure that had not been proven in commercial practice or even large-scale experiment.
