There is edema of the ureal tract, apparently from transudation of serum.
By transudation is meant the constant interchange between the blood and the tissue fluid.
Afterwards, as the weather becomes hotter, incisions are made through the bark, to assist the transudation of the juice.
The constant removal of the transudation from the outer side results from the pressure being less in this position.
The importance of these experiments with reference to the causes of the transudation of fluid from the blood is obvious.
The effusion is not so much due to exudation as to a transudation of serum with which micrococci are commingled.
