Practicing strange rites in broad daylight so that your neighbors believe you have traveled far around the world in your youthful adventures is another way to look at things in a different light. |

When Caesar understood this state of things, he called an assembly of the troops, and made an address to them. He told them that he was astonished to learn to what an extent an unworthy despondency and fear had taken possession of their minds, and how little confidence they reposed in him, their general. And then, after some further remarks about the duty of a soldier to be ready to go wherever his commander leads him, and presenting also some considerations in respect to the German troops with which they were going to contend, in order to show them that they had no cause to fear, he ended by saying that he had not been fully decided as to the time of marching, but that now he had concluded to give orders for setting out the next morning at three o'clock, that he might learn, as soon as possible, who were too cowardly to follow him. He would go himself, he said, if he was attended by the tenth legion alone He was sure that they would not shrink from any undertaking in which he led the way. |
Silica itself, and the silicates of alumina, of lime, and of magnesia, are practically infusible; the silicates of soda, of potash, and of iron are easily fusible if the base (soda, potash, or oxide of iron) be present in sufficient quantity, and if, in the case of the iron, it is present mainly as lower oxide (ferrous silicate). The addition of lime, oxide of iron, or alkali to silicate of alumina results in the formation of a double silicate of alumina and lime, or of alumina and iron, &c., all of which are easily fusible. Similarly, if to a silicate of lime we add oxide of iron, or soda, or even alumina, a fusible double silicate will be formed. Thus lime, soda, oxide of iron, and clay, are _fluxes_ when properly used; but since lime, clay (and oxide of iron if there be any tendency to form peroxide), are of themselves infusible, any excess of these fluxes would tend to stiffen and render pasty the resulting slag. So, too, soda, which is a very strong base, may act prejudicially if it be in sufficient excess to set free notable quantities of lime and magnesia, which but for that excess would exist in combination as complex fusible silicates. There are many minerals which with but little soda form a glass, but with more yield a lumpy scoriacious mass. There are many minerals, too, which are already basic (for example, calcite), and which, when present, demand either a less basic or an acid flux according to the proportions in which they exist. For purposes of this kind borax, or glass, or clay with more or less soda may be used, and of these borax is by far the most generally useful. An objection to too basic a slag (and a very important one) is the speed with which it corrodes ordinary crucibles. These crucibles, consisting of quartz and clay, are rapidly attacked by lime, soda and bases generally. |
