    CONTENTS. & CHAPTER I. ELEMENTS AND COMPOUNDS. Imponderable bodies. Ponderable bodies. The different states in which matter can exist. Exercises on the weight of gases. Some substances &in exist in each of these states. Exercises. All substances either simple or compound. Distinction between simple and compound substances. One of the objects of chemistry. Into how many classes the elements are divided. Tables of the elements. Other facts re- specting them. The elements capable of uniting together. Experi- mental exercises on the combination of two elementary bodies. Directions to teachers and the self-instructed Page 1 CHAPTER II. THE CONDITIONS NECESSAET POE COMBINATION. EXEECISES ON THE COMBINATION OP A COMPOUND WITH AN ADDITIONAL AMOUNT OP ONE OP ITS ELEMENTS. EXEECISES ON THE COM- BINATION OP TWO COMPOUND SUBSTANCES. IN WHAT WAY COMBINATION BEACHES ITS LIMIT. All chemical experiments either synthetical or analytical, or a com- bination of the two. The force which causes substances to unite contrasted with the other natural forces. Difference between a mere mixture of substances and a chemical compound. Chemical combina- tion attended with an evolution of heat, and frequently of light, attended sometimes with changes in colour and form. All the elements do not unite with equal facility. The temperature at which combination takes place varies with the different substances. Beau- tiful application, by Sir H. Davy, of the fact, that substances require a certain temperature for their combination. Evolution of heat and light regarded as a sign of destruction by the generality of persons ; the reason of this erroneous idea. All solid substances emit light when heated beyond a certain degree. Principle upon which all practical
