racters that distinguish it from inorganic matter—Its decomposition—State in 
which the mineral substances exist in it—Its simplest forms—Its sources—Equivo¬ 
cal generation, ........ 13-27 
II. Of organism and life.—Organised bodies—Their distinguishing characters— 
The organic force—Vital stimuli—Their mode of action—Distinguished from other 
stimuli—Not all equally necessary to the infant and adult—Nor to all animals 
alike—Death—Its cause—Decay and renovation of the organic material—The 
cause—Sources of the new matter, and renovation of the organic force, . 27-45

Functions of animals; their classification—Organic attraction—Animal excitability 
—Its laws—Exhaustion attended with material change—Effect of Exercise—Re¬ 
action; its laws—Stimuli; their mode of action—Medicinal agents; their classifica¬ 
tion, and mode of action—Brunonian theory, and theory of the contra-stimulists—

IV. 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 
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
