3097. The Pilose animals first originate through completion and combination of all the organs of sense. They are Æsthetic or Sensorial animals.

3098. The arrangement of animals, according to the organs of sense, coincides consequently with that derived from the anatomical systems, and each animal division is therefore determined by two principal organs, by a vegetative and an animal. Every animal is at once a vegetable and animal body, the inferior kinds being partly so, but the highest or the Pilose animals entirely so, or in every respect, i. e. in them are found all the anatomical systems, and all the sexual and sensorial organs.

3099. The signification of animals is accordingly as follows:

I. Anatomical Systems.II. Organs of Sense.
A. Vegetative Systems.A. Tegumental Sense.
1. Intestinal animals.1. OozoaProtozoa.
2. Vascular "2. Glandular animalsConchozoa.
3. Respiratory "3. Cutaneous "Ancyliozoa.
B. Animal Systems.B. Cephalic Senses.
4. Osseous animals.4. GlossozoaPisces.
5. Muscular "5. RhinozoaReptilia.
6. Nervose "6. OtozoaAves.
7. Sensorial "7. OphthalmozoaThricozoa.

The ovum divides into vitellus, and albumen, along with the calcareous shell, and into germ or envelopes; the intestine into pharynx or stomach, bowels and absorbent vessels, thus:

1. Gastric animalsVitelline animalsInfusoria.
2. Intestinal "Albuminous "Polyps.
3. Absorbent "Involucral "Acalephæ.

The sexual parts divide into female, male, and urinary organs; the vessels into veins, arteries, and hearts, thus:

1. Ovarial animalsVenous animalsMussels.
2. Orchitic "Arterial "Snails.
3. Renal "Cardiac "Kracken.

The annulated tegument divides into papillæ, feet, and wings; the respiratory organs into tegumental network or rete, into branchiæ and tracheæ, thus:

1. Papillary animalsReticular animalsWorms.
2. Pedal "Branchial Crabs.
3. Alary "Tracheal Flies.
