Example Sentences
When we add to these the larv� of flies and water beetles, the Crustaceans, Hydr� and Water Spiders, we must begin to realise that there are other things than a drowned natural fly for which the fish might mistake its imitation, with the materials of which it is made soaked in and drawn through the water.
Although experiments show that a simple plethora with great distension of the capillaries of the abdominal organs occasions no considerable increase of transudation, a different result follows a hydr�mic plethora25 induced by the injection of immense quantities of salt water into the blood-current—often six times as much liquid as the animal had blood.
A simple hydr�mic condition of brief duration has been proven, by experiment, insufficient to give rise to increased transudation, neither increased secretion nor increased flow of lymph taking place.
Experiments show that a simple acute hydr�mia produces no increased transudation, and that a chronic hydr�mia, if connected with dropsy, is likely to be influential by increasing the permeability of the wall.
Even in those cases where a hydr�mia and an oedema co-exist, the localization of the latter is favored by obvious disturbances of the function of the capillary walls, as in case of the cutaneous oedema after scarlatina.
