granulations with a thin pink pellicle. As the epithelium increases in
thickness it assumes a bluish hue and eventually the cells become
cornified and the epithelium assumes a greyish-white colour.

_Clinical Aspects._--So long as the process of repair is not complicated
by infection with micro-organisms, there is no interference with the
general health of the patient. The temperature remains normal; the
circulatory, gastro-intestinal, nervous, and other functions are
undisturbed; locally, the part is cool, of natural colour and free from
pain.

#Modifications of the Process of Repair.#--The process of repair by
primary union, above described, is to be looked upon as the type of all
reparative processes, such modifications as are met with depending
merely upon incidental differences in the conditions present, such as
loss of tissue, infection by micro-organisms, etc.

_Repair after Loss or Destruction of Tissue._--When the edges of a wound
cannot be approximated either because tissue has been lost, for example
in excising a tumour or because a drainage tube or gauze packing has
been necessary, a greater amount of granulation tissue is required to
fill the gap, but the process is essentially the same as in the ideal
method of repair.

The raw surface is first covered by a layer of coagulated blood and
fibrin. An extensive new formation of capillary loops and fibroblasts
takes place towards the free surface, and goes on until the gap is
filled by a fine velvet-like mass of granulation tissue. This
granulation tissue is gradually replaced by young cicatricial tissue,
and the surface is covered by the ingrowth of epithelium from the edges.
