Part 43

Sub-serous cellular texture.—It is in general loose and abundant.—Why.—Place where it is dense. 92

Cellular texture exterior to the arteries.—Its peculiar nature is analogous to that of the sub-mucous texture.—Its relations with the arterial fibres.

Cellular texture exterior to the veins.—It is analogous to the preceding, only less thick.—Remarks.

Cellular texture exterior to the excretory ducts.—The same structure and arrangement as in the preceding. 96

Of the cellular system considered in relation to the organs that it surrounds on all sides.—Cellular atmosphere.—Fluids of this atmosphere.—Insulation of the vitality of the organs.—Of this atmosphere considered as a means for the propagation of diseases.—It favours the motion of the parts. 96

II. Of the Internal Cellular System of each Organ.

Arrangement of this texture.—Its uses.—Its different proportions. 102

ARTICLE SECOND.

OF THE CELLULAR SYSTEM CONSIDERED INDEPENDENTLY OF THE ORGANS.

I. Of the Cellular System of the Head.

Cellular texture of the cranium.—It is almost nothing within.—Its communications.—Consequences of these communications.—It is more abundant without.

Cellular texture of the face.—It is very abundant.—Its uses.—Its communications, &c. 104

II. Of the Cellular System of the Trunk.

Vertebral cellular texture.—It is not abundant in the cavity of the canal.—On the exterior, there is but little behind, and more in front.—Consequences.

Cervical cellular texture.—It is abundant.—Its communications.—Consequences.

Pectoral cellular texture.—It is found especially upon the median line.—Its communications.—External texture.

Abdominal cellular texture.—Of the parts in which it is most abundant.—Its communications.

Cellular texture of the pelvis.—It is very abundant.—Why.—Consequences.—Its communications. 108

III. Of the Cellular System of the Extremities.

Its different proportions in the superior and the inferior. 112

ARTICLE THIRD.

OF THE FORMS OF THE CELLULAR SYSTEM, AND THE FLUIDS IT CONTAINS.

I. Of the Cells.

Their form.—Their capacity.—Their communication.—-Experiments.—Of the cellular permeability.—In what sense it should be understood. 114

II. Of the Serum of the Cellular Membrane.

Proof of its existence.—Its evaporation.—It varies in the different regions.—Method of ascertaining the proportions of it.—Experiments.—Nature of this fluid.—Experiments. 117

III. Of the Cellular Fat.

Natural proportions of the fat.—Varieties of its proportions according to the regions, organs, systems, &c—Its peculiar arrangement in childhood.—Varieties according to the other ages. 119
