GENERAL ARRANGEMENT OF THE EXHALANTS.

I. Origin, Course and Termination.

Different hypotheses respecting these vessels.—What observation shows us concerning them. 69

II. Division of the Exhalants.

They can be referred to three classes.—Table of these classes and their division. 71

III. Difference of the Exhalations. 73

ARTICLE SECOND.

PROPERTIES, FUNCTIONS AND DEVELOPMENT OF THE EXHALANT SYSTEM.

I. Properties.

We are ignorant of those of texture.—The organic are very evident in it. 74

Characters of the Vital Properties.—They vary in each system.—Consequences as it regards functions. ib.

II. Of Natural Exhalations.

They are all derived from the vital properties.—They vary consequently like these properties.—Proofs.—Of sympathetic exhalations. 75

III. Of Preternatural Exhalations.

Sanguineous exhalation.—Hemorrhage of the excrementitious exhalants.—Hemorrhage from the skin.—Hemorrhages from the mucous surfaces.—They take place by exhalation.—Proofs.—Experiments.—Of active and passive hemorrhages.—Differences between hemorrhages by rupture and by exhalation, between those of the capillaries and those of the great vessels. 78

Hemorrhages of the recrementitious exhalants.—Hemorrhages of the serous surfaces.—Observations concerning dead bodies.—Cellular hemorrhages.—Other hemorrhages of the exhalants. 85

Preternatural exhalations, not sanguineous.—Varieties of the exhaled fluids, according to the state of the vital forces of the exhalants.—Different examples of these varieties. 87

IV. Of the preternatural development of the exhalants.

It is especially in cysts that it takes place.—The secreted fluids are never preternaturally poured out like the exhaled.—Why.—Of the natural emunctories. 88

ABSORBENT SYSTEM.

GENERAL OBSERVATIONS.

ARTICLE FIRST.

OF THE ABSORBENT VESSELS.

I. Origin of the Absorbents.

Table of absorptions.—Of external absorptions.—Of internal absorptions.—Of the nutritive absorptions.—It is impossible to know the mode of origin of the absorbents.—Interlacing of the branches. 91

II. Course of the Absorbents.

Their division into two layers, superficial and deep-seated.—Their arrangement in the extremities and the trunk. 95

Forms of the absorbents in their course.—They are cylindrical, full of knots, &c.—Consequences of these forms.—The absorbents have not as great capacity during life as in the dead body. 97
