An Essay on the sanguineous apoplectic Congestion in 
Sheep, known under the Names of “ Blood,” “ Blood 
in the Spleen,” & c. 
By M. P. Charlier, V.S., Rheims. 
[Continued from page 179.] 
Individual predisposing Causes . — WHERE all other things are 
equal, this disease, when it breaks out among a flock, chiefly 
attacks young lambs, and lambs of one and two years old, or such 
as are in better condition than the rest of the flock, and sheep 
from three to four years old ; and, above all, it selects the finest 
animals, those which feed and thrive well, and which are known 
to observers under the characteristic denomination of sheep that 
have the blood, or too much blood. 
Ewes in an advanced stage of gestation often fall victims to it 
in them the sanguineous congestion almost always declares itself in 
the womb, produces miscarriage or a very painful and unnatural 
labour. If submitted to the same regimen as the ewes which are 
suckling, when they do not die within a day or two after the mis- 
carriage, they get remarkably fat, and then die in about three 
weeks or a month. Ewes which have not borne lambs, when 
submitted to similar conditions, are in the same state. 
Sheep weakened by previous scanty feeding are less exposed 
to this disease ; in them the congestion only declares itself, if we 
may make use of the phrase, by accident; that is to say, when 
they are suddenly changed from a scanty supply of food to an 
abundance of green or dry fodder abounding in nutrition, and very 
rich. The disease in general appears accompanied with external 
hemorrhage, and effects its ravages with frightful rapidity. 
Sheep well kept, and according to a certain regimen, such as 
are being fattened, for instance, having gradually and for some con- 
siderable time become habituated to heating fodder, are more rarely 
attacked by blood than others. 
Lastly, ewes that are suckling, and white lambs, unless too 
highly fed, and on too exciting fodder, rarely fall victims to it. 
Let us now approach a question most interesting not only to 
veterinary practice but also to public health : we will speak of 
contagion. This disease, blood in the sheep, is it contagious!
