The properties common to organic and inorganic bodies.—1. Electricity; its sources generally. Electric fishes. Electric phenomena in frogs. Electricity in the human body. 2. Development of heat.—In man. In warm-blooded animals. At different ages. Effects of external cold on warm-blooded animals,—hybernation. Cause of hybernation. Effects of external heat. Development of caloric in cold¬ blooded Vertebrata. In invertebrate animals. Sources of animal heat. In respira¬ tion. In organic processes. In nervous influence. 3. Development of light in animals.—Phosphorescence of the sea. Luminous insects. Development of light in the higher animals and in man, . ..... 66-96 SPECIAL PHYSIOLOGY. BOOK I. GENERAL ANATOMY. SECTION I—Of histogeny, or the formation and development of the tissues. Component proximate principles of the tissues.—Contain the same organic elements. The group of fibrin, albumen and casein represented by protein. Fibrin, dried and solid; albumen in solution and coagulated; casein, gelatin; fatty matter, . 97-105 Chap. I.—Histogeny—the- formation and development on the animal tissues.— Schleiden’s observations on the newly formed tissues of plants. Their origin in gum or fecula. Homogeneous fluid of the ovule gives rise to minute granules. Cytohlasts.—These constitute the nuclei which coagulate and give origin to cells. Young cells projecting from older ones. All tissues developed from nucleated cells. Cartilages at first consist entirely of cells with rounded granular nuclei. Cell developed in a structureless substance or cytoblastema. Arrangement of tissues according to their mode of development. Of special tissues. Epithelium. Pigment cells. Nails. Feathers. Crystalline lens. Cartilage and bone. Teeth. Cellular tissue. Tendinous tissue. Elastic tissue. Muscles. Nerves. Schwann’s general
