SECOND LESSON. Recapitulate the last lesson, and then proceed to furnish the idea of a verb.

Having obtained a list of nouns once more from the children, which may be written upon the black-board, or on their own slates, the Teacher should ask them what they have seen the things they have named do, as boys run; girls sew; clocks strike. The columns may thus be formed with spaces (or lines) between them, separating the nouns from the verbs, the words nouns and verbs being written at the top. The children's vocabulary may in this way be well nigh exhausted. One child may be called upon to read his column of nouns or name-words, and afterwards another his column of words denoting actions. It may be well to teach them to distinguish between the words which are the names of things and places, and the words denoting action, before the terms nouns and verbs are given, it being sometimes difficult to know whether a wrong answer is given from confounding the terms, which is an error of memory, or from mistaking principles by an error of the understanding. Life is imparted into a class or gallery by constituting the remainder judges of the performances of one-while one is reading his list of nouns, let any be told to express their dissent by holding up their hands, and whoever is wrong will have an opportunity of being corrected. The children will now perceive that one column points out agents or actors and the other actions or things done ; the former in grammar being called nouns, the latter verbs. Now require examples under the new names.

HYDRO-CARBONS.

There are two chief compounds of Carbon and Hydrogen, on the presence of which coal-gas depends for its illuminating power. They are the heavy and light carburetted Hydrogen.

Heavy CARBURETTED HYDROGEN. - Symbol C,H,: Procured from the action of 2 or 3 measures of Sulphuric Acid vpon one of Alcohol. Apply heat when the mixture becomes dark and the gas is rapidly given off. Thus : Before Decomposition .... HO, SO, + C, H, O, (Alcohol)

HO, SO2 + C, H, 2 HO
After Docomposition.. HO, SO, + 2 HO + C,HA

or

It will be observed that the effect of the Sulphuric Acid is to draw off the water from the Alcohol.

Properties.—Very combustible, invisible and colorless, does not support combustion. While burning, produces Carbonic Acid (CO,) and water (HO) the Oxygen of the air combining with its Carbon and its Hydrogen. Exp. I. Ignite a jar of the gas and shew how it is that coal-gas obtains its brightness. Exp. 2. A strong jar having three quarters of Oxygen and one quarter of the gas, gives a loud explosion, when fired. Care must be observed in the experiment. Exp. 3. Observe its singular action when burned with Chlorine. Fill a jar with Chlorine and this gas equally over water. They will rapidly unite and form an oily substance on the surface of the water. From this circumstance it obtains its more usual name of Olefiant Gas. Exp. 4. If the Chlorine be mixed with the Olefiant Gas in the ratio of two to one and ignited, the Chlorine will unite with the Hydrogen and the presence of the liberated Carbon will be observed in a thick smoky flame.

The presence of Carbon and Hydrogen may be demonstrated easily in ordinary combustible substanı:es. The Hydrogen may be seen by the dew deposited in a glass tube held over a flame. The Carbon may be shewn by the black mark upon a plate held over it.

Light CARBURETTED HYDROGEN.-Symbol CH2 Called also marsh gas or will-o-the-wisp and fire-damp, being naturally produced from decaying vegetable matter and in coal mines. Procured artificially by subjecting to strong heat equal parts of crystallized acetate of soda and caustic patass with half as much powderered quicklime. Its illuminating power not so great as in the last gas, but it detonates powerfully when mixed with ten times its measure of air or twice of Oxygen,
