SANGUINEOUS APOPLEXY. 
the herbage is fine, drawn up, and but slightly tufted than in those 
where the arable soil is essentially peaty, or muddy and damp, 
or when the herbage shoots plentifully, is light, and not very 
succulent. 
3d. That it manifests itself particularly in the fold Avhen the 
summer is dry, and the flock, weakened by a scanty allowance, is 
suddenly folded on a rich pasturage that feeds them to satiety ; 
and during winter, when the sheep are allowed too large a ration 
of rich and nutritive food, such as vetches, tares, lentils, barley, 
oats, &c. &c. 
4th. That sheep which are regularly well kept, and occasionally 
over-fed, are more liable to the internal sanguineous congestion 
known as blood in the spleen, than to the sanguineous congestion 
attended with external hemorrhage. Green food, and particularly 
common clover, suddenly given in great abundance, is sure to pro- 
duce this first variety of the disease of the blood ; whereas tares 
and all heating grains have a tendency to determine the external 
sanguineous congestion. 
5th. That in farms the managers of which have the good sense 
to give turnips, beet-root, or other roots with heating grains, or 
even boiled grain, which, although highly nutritious, passes very 
gradually from one mode of feeding to another, the disease rarely 
appears, or, if it does so, is not nearly so fatal. 
6th. Lastly, I* have myself repeatedly observed that sanguineous 
congestion is almost entirely unknown to small farmers, who ge- 
nerally have no artificial meadows, and are obliged to pasture their 
sheep as well as they can on the skirts of woods, by road-sides, 
&c., and in all kinds of weather; and that this affection will at the 
same period and in the same district be making frightful ravages 
among the beautiful flocks of our great agriculturists, while the 
small farmers’ half-fed and often weakly sheep entirely escape. 
The insalubrious air of close ill-ventilated sheep-folds, where 
the animals are crowded together, the putrid emanations arising 
from stagnant water, marshes, ponds, drains, &c., are causes which 
rarely, if ever, exist among us, but which might, undoubtedly, 
produce putrid or typhoid fever in animals predisposed for disease 
of the blood; but where such is the case, it arises from a merely 
accidental complication, which is as liable to take place here as 
under any other circumstances. 
I am not of opinion that ameliorating the land with manure 
has any thing to do with the development of this disease ; for on 
many farms where the greater part of the flock have fallen victims 
to this disease, the soil has been scarcely if at all manured ; while 
in other places, where manures are plentiful, and the land is tho- 
roughly and frequently dressed with peat ashes, lime, and marl,
