These Lectures will be divided into four Parts, of which the First is now ready; the others are in course of publication, and the whole will be completed in two volumes.
Outline of Part I.—“ On the Organic Constituents of Plants. ”—Lecture I. Elementary substances of which plants subsist. II. and III. Compound substances which minister to the growth of plants. IV. Sources from which plants immediately derive their elementary constituents. V. How the food enters into the circulation of plants—general structure of plants. VI. Into what substances the food is changed in the interior of plants—substances of which plants chiefly consist. VII. Chemical changes by which the substances of which plants chiefly consist are formed from those on which they live. VIII. How the supply of food for plants is kept up in the general vegetation of the globe.
Outline of Part II.—“ On the Inorganic Constituents of Plants—the Origin, Classification, and Chemical Constitution of Soils—General and Special Relations of Geology to Agriculture—Origin, Constitution, Analyses, and Methods of Improving Soils in different Districts and under unlike conditions. —Lecture IX. Kind and proportion of inorganic matter contained in plants. X. Properties of the inorganic compounds which exist in vegetable substances, or which promote their growth. XI. Of the nature, origin, and classification of soils—Structure of the earth’s crust—Classification and general characters of the stratified rocks—Agricultural capabilities of the soils derived from them. XII. Granite and trap rocks, and the soils derived from them—Superficial accumulations. XIII. On the exact chemical constitution, the analysis, and the physical properties of soils.
