![FEBRUARY 17, 1858. PHYSIOLOGICAL TISSUES. Falsity of the view that tissues and fibres are made up of globules (elementary granules)—The investment theory (Umhullungstheorie)—Equivocal [spontane* ous] generation of cells—The law of continuous development. General classification of the tissues—The three categories of General Histology— Special tissues—Organs and systems, or apparatuses. The Epithelial Tissues—Squamous, cylindrical, and transitional epithelium— Epidermis and rete Malpighii—Nails, and their diseases—Crystalline len3— Pigment—Gland-cells. The Connective Tissues—The theories of Schwann, Henle, and Reichert—My theory—Connective tissue as intercellular substance—Cartilage (hyaline, fibro- and reticular)—Mucous tissue—Adipose tissue—Anastomosis of cells ; juice- conveying system of tubes or canals. In my first lecture, gentlemen, I laid before you the general points to be noted with regard to the nature and origin of cells and their constituents. Allow me now to preface our further considerations with a review of the animal tissues in general, and this both in their physio- logical and pathological relations. The most important obstacles which, until quite recently, existed in this quarter, were by no means chiefly of a pathological nature. I am convinced that pathological conditions would have been mastered with far less difficulty if it had not, until quite lately, been utterly impossible to give a simple and comprehensive sketch of the physiological tissues.
