The _kidneys_ may be pale except where blood stained and œdematous infiltration of the surrounding tissue may be marked. Serous effusion into the peritoneum is not rare. The _eyelids_ are often implicated, infiltrated thickened, and rigid, and the conjunctiva, bulbar and palpebral, the seat of extensive petechiæ. Barreau mentions extravasations on the divisions of the lumbosacral plexus causing sudden paraplegia. Petechiæ and hæmorrhages mark endocardium, pericardium and cardiac muscle, otherwise the muscle is pale. The blood is sometimes in firm clot, at others diffluent or nearly incoagulable. _Symptoms._ If hyperthermia is not already present as a feature of the pre-existing malady it usually shows itself early, at first slight, it may be (101° F.), and afterward rising in some cases to 104° to 106° F., or even higher. The general symptoms are usually those of the pre-existing disease (strangles, contagious pneumonia, influenza, nasal catarrh, pharyngitis, bronchitis, etc.), pursuing, it may be, a persistent course, or attended by special toxæmic symptoms of prostration and other signs of depression of vital functions. In some cases the hyperthermia is either absent at this stage or overlooked. On the prostration supervene the petechiæ on the visible mucosæ, and often also the swellings of the skin and subcutis. One of these may be seen before the other and it is difficult to decide whether the petechiæ always appear first as has been claimed. Cadeac claims that when œdema is first seen it has been preceded by petechiæ in that tissue (skin). The _petechiæ_ are usually first noticed on the nasal mucosa as fine red points, pin’s heads, or up to half an inch in diameter, or a number of these have coalesced to form extensive patches, and by and by to cover the entire wall. At first the mucosa is spotted with purple, without any marked elevation of the surface, but as the lesions extend it becomes swollen and raised at the points of extravasation and immediately around them and oozes a serous, sometimes a pinkish or yellow fluid. Even in the smallest petechiæ the color is persistent and does not disappear on pressure like the blush of the adjacent mucosa.
