About This Book

This work presents a systematic, observational study of plant structure and function, describing the internal organization of seeds, roots, stems, leaves, flowers, fruits, and seeds as revealed by close inspection and a microscope. It maps tissues and organs, explains the movement of sap and air, and analyses the generation and distribution of plant fluids and substances such as milks, oils, and salts. Additional lectures examine leaf and flower anatomy, coloration, tastes, and soluble salts, and the text includes comparative tables and explanatory notes to support a mechanical and physiological account of vegetation.

ANATOMY.

PART II.

AVING before given the Anatomy of Trunks; I shall next proceed to see, what Use may be made thereof; and principally, to explicate the manner of their Vegetation. In doing which, that former Method, which I used in shewing the manner of the Growth of Roots, I shall not exactly follow. For so, in regard the Organical Parts of the Root and Trunk are the same, and consequently their Nutrition and Conformation are effected in the same way; I should hereby be obliged to a nauseous and unprofitable repetition of many things already said. The Explication therefore of all those Particulars, which more especially belong to the Trunk, or are more Apparent therein, and not spoken of, or not so fully, in the former Books, will be my present Task. The chief Heads whereof, shall be these Seven following, viz.
FIRST, the Motion and Course of the Sap.
SECONDLY, The Motion and Course of the Aer.
THIRDLY, The Structure of the Parts.
FOURTHLY, The Generation of Liquors.
FIFTHLY, The Figuration of Trunks.
SIXTHLY, The Motion of Trunks.
SEVENTHLY, And lastly the Nature of Trunks as variously fitted for Mechanical Use.
