P. 91.—“Gallic Confession.” This was essentially Calvinistic in its import, as were also the system of government and method of discipline adopted. They were, however, modified somewhat, to suit a church—not like that at Geneva, in union with the state, but antagonistic to it. “Bourbons.” This line of kings in France began with Henry IV. Six of his descendants in direct line occupied the throne after him. The Louises XIII., XIV., XV., XVI., XVIII., and Charles X. The last representative of this line was the Count de Chambord, who died in 1883. There is a younger branch known as the Orleans branch. “Guises,” gheez.

P. 169.—The formula (N₂O₂) shows that two atoms of nitrogen have united with two atoms of oxygen to form a molecule of nitrogen di-oxide. The formula Cu (NO₃)₂ shows that one atom of copper has united with two molecules, each composed of one atom of nitrogen and three atoms of oxygen, to form one molecule of cupric nitrate. In like manner Fe₂ (NO₃)₆ indicates that two atoms of iron have united with six molecules, each composed of one atom of nitrogen and three atoms of oxygen, to form one molecule of ferric nitrate. P. 173.—“Refractive power” of water. When a ray of light strikes the surface of a new medium, a portion of it is turned out of its original course or refracted. This gives rise to some well-known effects. When any object is placed in water and viewed obliquely it looks to be nearer the surface than it is, because the light in passing from the denser medium takes a direction more inclined to the horizontal, and an object always appears directly in line with the ray of light entering the eye.
