To be master of the sea, is an abridgment of a monarchy. Cicero, writing to Atticus of Pompey his preparation against Caesar, saith, Consilium Pompeii plane Themistocleum est; putat enim, qui mari potitur, eum rerum potiri. And, without doubt, Pompey had tired out Caesar, if upon vain confidence, he had not left that way. We see the great effects of battles bv sea. The battle of Actium, decided the empire of the world. The battle of Lepanto, arrested the greatness of the Turk. There be many examples, where sea-fights have been final to the war; but this is when princes or states have set up their rest, upon the battles. But thus much is certain, that he that commands the sea, is at great liberty, and may take as much, and as little, of the war as he will. Whereas those that be strongest by land, are many times nevertheless in great straits. Surely, at this day, with us of Europe, the vantage of strength at sea (which is one of the principal dowries of this kingdom of Great Britain) is great; both because most of the kingdoms of Europe, are not merely inland, but girt with the sea most part of their compass; and because the wealth of both Indies seems in great part, but an accessory to the command of the seas. |
~Indirect Titration.~--The action of permanganate of potash upon a ferrous solution is one of oxidation, hence it is evident that if any other oxidising agent is present it will count as permanganate. In such a case the titration can be used (indirectly) to estimate the quantity of such oxidising agent, by determining how much less of the permanganate is used. For example, suppose that 1 gram of iron dissolved in sulphuric acid requires 100 c.c. of standard permanganate to fully oxidise it, but that the same amount of iron only requires 35.6 c.c. of the same standard permanganate if it has been previously heated with 0.5 gram of black oxide of manganese. Here it is evident that 0.5 gram of black oxide does the work of 64.4 c.c.[4] of the permanganate solution, and that these quantities are equivalent; moreover, if 64.4 c.c. correspond with 0.5 gram, then 100 c.c. correspond with 0.7764 which is the standard. On theoretical grounds, and by a method of calculation which will be explained further on (under the heading "Calculations from Formulæ"), it can be found that if the standard for iron is 1 gram, that for the black oxide will be 0.7764 gram. |

It will be seen how much we owe to patient investigators. The results are, indeed, bewildering. They make us acquainted with a people the very existence of whom was not known a few years back. Though the whole life of those ancient races seemed hopelessly lost in the night of time, the gloom is irradiated by the light of modern science, which lays before our astonished vision the remains of arts and industries of the primitive tribes that occupied Europe during the morning-time of human life. | ||
