THE PROPERTIES OF MATTER--IMPENETRABILITY.
In the present state of our knowledge it seems to be universally agreed, that we cannot properly commence even popular discussions on astronomy, mechanics, and chemistry, or on the imponderables, heat, light, electricity, and magnetism, without a definition of the general term "matter;" which is an expression applied by philosophers to every species of substance capable of occupying space, and, therefore, to everything which can be seen and felt.
The sun, the moon, the earth, and other planets, rocks, earths, metals, glass, wool, oils, water, alcohol, air, steam, and hosts of things, both great and small, all solids, liquids and gases, are included under the comprehensive term _matter_.
Such a numerous and varied collection of bodies must necessarily have certain qualities, peculiarities, or properties; and hence we come in the first place to consider "The general powers or properties of matter."
Thus, if we place a block of wood or stone in any position, we cannot take another substance and put it in the space filled by the wood or stone, until the latter be removed.

Chapter 2 of The Boy's Playbook of Science by John Henry Pepper holds 94 sentences, grouped into 19 reading sections of at most 5 sentences.

Every word can be tapped for its pronunciation and dictionary entry.

What does chapter 2 of The Boy's Playbook of Science contain?

Chapter 2 holds 94 sentences of The Boy's Playbook of Science, unabridged, divided into 19 reading sections.

This page carries chapter 2 of The Boy's Playbook of Science by John Henry Pepper exactly as it stands in the source edition, without abridgement. It runs to 94 sentences, grouped into 19 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 2 of The Boy's Playbook of Science?

Work through the 19 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 19 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 2 be read aloud to me?

Yes — every sentence and every individual word in chapter 2 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
