    4. As a scaling (desquamatio). We understand by these exclusively, the abundant shedding of epithelial cells. If this is at the same time combined with a considerable secretion of fluid, we make use of the expression catarrh, in that we generalize a designation, which especially suits the catarrh of the nasal mucous membrane, in so far that here the morbid secretion flows from the nares and sinuses, xara^el. 5. As a fiat, bed-like [garden-bed] tumefaction. This corresponds to the uniform enlargement from all sides of parenchymatous organs, and like this is occasionally designated as hypertrophy. The dis- tinction also between genuine and false hypertrophy again recurs. That which distinguishes them from uniform enlargements, is the cir- cumstance, that it may indeed extend over very great tracts of a membranous organ, but yet not over the whole of it; that it somewhere touches upon the sound portion, and thereby experiences a limitation as to space, which has also procured it the name of island-like tume- faction. This occurs in many chronic inflammations of the external integument, arterial coats, in typhus and in many cancers. 6. As the tuberosity (tuber). The more the height of a circum- scribed tumefaction increases, the surrounding level remaining the same, the more is it a tuberosity. The height and profile of the tuberosity may vary within certain limits; a very much elongated one is called a wart (papilla). The base, however, always remains the broadest part. If the base of a tuberosity decreases, its edges must necessarily hang over, the new formation appears— 7. As a fungus, or 8. As a pediculated tumor (polypus). The difference between the fungus and polyp depends essentially upon the various manner and mode as to how the diminution of the base of the tuberosity is pro- duced. If it is only relative, that is to say conditioned by the pre- dominant proliferation in the prominent parts of the tuberosity, we make use of the designation, fungus. The fungus has a broad pedicle and a flat top. If, however, an absolute diminution of the base is associated with this relative one, in that the top ever becoming more massy draws and drags upon its base, be this by its own weight, or be it by other forces which tend to move it about, the latter is reduced to a comparatively thin pedicle, a polyp is formed. 9. As dendritic vegetation. This is incontestably the highest devel- opment of form which a circumscribed elevation of the surface can experience. As the name implies, it is a tree-like ramification of the ground-plan of the same. We have a trunk, we have branches, which go off at various angles, and we have occasionally upon the smallest twigs, leaves or berries. As is known, we find the same design in glands with branching excretory ducts, the so-called racemose glands. The uniformity in the first design and development of these glands with the dendritic vegetations proceeding from the outer skin and the
