The surface is cribriform, and a purulent secretion may be pressed out fromfollicular openings.
Sycosis is limited to the hairy region of the face, is distinctly a follicular inflammation, and is rarely very itchy; eczema is diffused, usually involves other parts of the face, and itching is an annoying symptom.

In the individual spots we may frequently observe one or several minute, darker-colored papules, due to follicular congestion, which when more intense constitutes the morbilli papulari presently to be described.
The situation of follicular ulcerations is almost always in the large intestine, and they vary considerably in number: sometimes only a few follicles are thus affected, while in other cases the bowel is crowded with them.
Follicular enteritis hastens, and tuberculous ulceration of the mucous membrane speedily brings, the case to a fatal termination.
Primarily, at least, it does not involve the follicles of the tonsils which open into the lacunae, and is therefore incorrectly denominated follicular tonsillitis, although it is most generally so described.
Besides follicular ulcers the mucous membrane is disorganized by ulcers which have their origin in a loss of epithelium and superficial erosion.

The spawning of Fishes, usually annual, corresponds to ovulation in Mammals, and in the ovary after spawning the numerous collapsed follicles containing the follicular cells may be seen in all stages of absorption.
The ovum being no longer present in the ovary, the secretions would remain in the follicular cells, and the corpus luteum would be explained.
Moreover, the hypertrophied follicular cells which constitute the corpus luteum secrete fat which is seen in them in globules.
The presence of this hormone might cause the follicularcells to behave as though the ovum was still present in the follicle, so that they would persist and not die and be absorbed.
The left and larger gonad had a quite similar structure, but at its lower end were found two ova enclosed within a follicular epithelium.
The essential process in the development of these structures is the hypertrophy and, in some cases at least, multiplication of the follicular cells in the ruptured follicle.
Numbers of ova die without reaching maturity, the follicular cells degenerate, and the follicle becomes filled with the cells of the theca interna, which have a resemblance to those of the true corpus luteum.

During the stage when the follicular epithelium has the above structure, its cells have a character similar to that of the goblet-cells of a mucous membrane, and pour out their metamorphosed protoplasm into the body of the ovum.
If the view about the epithelium here adopted is correct, the epithelium without doubt corresponds to the follicular epithelium of other ova, and has the same origin as the ova themselves.
The plications of the follicular epithelium give rise to a basket-work tracery on the surface of the ovum.
They surround the enlarged cell which forms the true ovum, for which they constitute a kind of follicular capsule.
The cells of the inner layer of this capsule soon assume an epithelial character, and become a definite follicular epithelium, while between the two layers there penetrates a network of vascular channels.
Around it is a flat follicular epithelium enclosed in a membrana propria folliculi.
While some of these cells enlarge and become ova, the remainder supply the elements for a follicular epithelium, which is established round the ova, exactly as in Holothurians.
The formation of both these membranes from the protoplasm of the ovum is rendered certain in the latter case by the absence of a follicular epithelium.
The thickened germinal epithelium gives rise (in the case of the female) to the ova and the follicular epithelium.
In the nearly ripe ova of Asterias Fol has described a flattened follicular epithelium the origin of which is unknown.
The follicular epithelium becomes after the establishment of these vascular channels folded in a most remarkable manner.
Although it is not generally present in a distinct form, there is always a passage connecting the ovum and yolk cells, even when the follicular epithelium grows in and nearly separates them.
The follicular appendages of the branchial arteries present remarkable differences in their external appearance.
Antheridia borne in follicular bodies on the surface of a separate thallus.
Friction and other influences aggravate the inflammatory process, so that erosions, granular and cystic degenerations, follicular ulcers and chronic enlargements, become complications of the catarrhal inflammation of the cervix.
In the human female the ovaries are two follicular glands, about the shape and size of small almonds, situated on each side of the uterus.
Whether the inflammation is follicular or interstitial or both combined, it is liable to destroy all the follicles or ovisacs which contain the ova, that are essential to procreation, and the consequence will be sterility.
The morbid anatomy showed in the mucous membrane of the great intestine the three degrees of congestion, follicular ulceration and sloughing of the whole mucous coat (in the sigmoid flexure and rectum).
The morbid anatomy was that of true dysentery--follicular ulceration in the transverse colon, with occasional sloughing of large pieces of the mucous membrane.

The original membrana propria folliculi is still present round thefollicular epithelium, but is closely associated with a fibrous layer with elongated nuclei.
Coincidently with this change in the follicular epithelium the commencement of the atrophy of the membranes of the ovum, described in the last section, becomes apparent.
The vitellus is granular, and provided with a distinct, though delicate membrane, which has every appearance of being a product of the ovum itself rather than of the follicular epithelium.

When the egg is nearly ripe, and the vitelline membrane has been reduced to a mere remnant, the follicular epithelium is still very columnar (Pl.
Nor can I state for the last-described stage anything about the character of the follicular epithelium in the neighbourhood of the germinal vesicle.
The ingrowths of the stroma are, moreover, directed towards individual ova, around which, outside the follicular epithelium, they form a special vascular investment in the succeeding stages.
In the ovaries of very young animals the cells of the follicular epithelium are more columnar on the side towards the stroma than on the opposite side, but this irregularity soon ceases to exist.
The follicular epithelium, though not always formed from the pseudo-epithelium, is of course always composed of cells derived from the germinal epithelium.
There cannot be the smallest doubt that the follicular epithelium is derived from the general cells of the germinal epithelium--a point on which my results fully bear out the conclusions of Ludwig and Semper.
From this stage onwards, both vitelline membrane and zona gradually atrophy, simultaneously with a series of remarkable changes which take place in the follicular epithelium.
The outer one corresponds with the membrane usually regarded in other Vertebrates as a chorion or product of the follicular epithelium, but, by tracing it back to its first origin, I have been led to reject this view of its nature.
The cells of the germinal epithelium give rise both to the permanent ova and to the cells of the follicular epithelium.
Each ovum is surrounded by a follicular epithelium which is nourished by numerous blood-vessels, and which penetrates into the surface of the ovum in numerous folds.
