SANGUINEOUS APOPLEXY. 
171 
Such are the symptoms, the progress, and termination of internal 
apoplectic congestion, known by the name of blood in the spleen. 
But when the hemorrhage declares itself simultaneously in the 
organs of these large splanchnic cavities, and in the sub-cutaneous 
tissues, and especially when the external hemorrhage predominates, 
the course of the disease is less rapid; and to the symptoms, 
common to these two varieties of this affection, are united different 
outward signs. The skin of the natural openings, and all the visi- 
ble mucous membranes, become pale or blue — the superficial veins 
are depressed — the sheep limps first with one leg, then with 
another ; but it is (he hinder limbs which are generally affected. 
The animal is dull, depressed, out of breath, ceases to eat, and 
loiters behind the rest of the flock. Large ill-defined tumours of 
a reddish violet hue appear under the skin, chiefly on the inguinal 
and axilliary regions, but sometimes on the loins and throat. These 
tumours, that soon extend themselves both in length and breadth, 
take on a blueish tint, and then become black, and propagate them- 
selves rapidly under the form of infiltration over the internal sur- 
face of the thigh or the legs, or from the dorso-lumbar region to the 
lateral surface of the abdomen and thorax.- Blood is then shed in 
the tissues, begins to decompose, and its constituent elements se- 
parate. The tumefied parts are rapidly increased in bulk by this 
sanguineous infiltration. The tumours extend themselves in all direc- 
tions over the body, giving to the skin a livid tint, which is deeper 
according as the cellular tissue is loose or abundant, the sanguineous 
collection great or small, and the skin coarse or fine. The animal 
then falls; sometimes it swells; it breathes with difficulty; the 
air expired is cold, the extremities and the surface of the body 
grow cold, and if an internal hemorrhage has suddenly come on in 
the interior of the abdominal or pectoral organs, at the same time 
with the external tumours, a discharge of more or less pure blood 
will be seen flowing from all the natural openings, and the animal 
soon dies. 
Under these two forms, the disease will sometimes destroy the 
animals attacked in less than twenty minutes. At other times it 
will last several hours. Lastly, when the exterior hemorrhage 
predominates, and especially when it has its seat in the posterior 
regions of the body, this affection may last two or three days. 
Post-mortem Appearances : the Examination made at the 
moment of the supervention of the Hemorrhage in both Varieties of 
the Disease. — If the animal is destroyed at this stage of the disease 
by effusion of blood, and the congestion and hemorrhage have been 
principally declared in the external regions, the skin, the cellular 
tissue, and the flesh of the healthy parts and the internal organs 
offer no abnormal appearances, but in skinning the carcass a great
