ordinarily in great numbers, under the microscope. The urine, 
lymph, as well as the abundant serous, or gelatin if orm exudations 
which lubricate the tissues and the carbuncular localizations, 
internal as well as external, have a reddish or brownish color, and 
are nearly always very rich in bacteridies. The diseased lym¬ 
phatic glands , especially those closed at the points where the 
introduction of the microbs has taken place, are blackish or 
brownish. Their structure is soft and disorganized, and, so to 
speak, saturated with those organisms. The subcutaneous and 
interorganic cellular tissue is oedematous in large places, and often 
the seat of great bloody extravasations, more or less circum¬ 
scribed. Generally the muscles are also full of bloody serosity, 
and upon transverse section, present hemorrhagic centers of very 
dark color. Sometimes entire groups of muscles are softened, 
and present a black or dark red aspect, while others are very pale 
and easily torn, as if they had been boiled in water. In the ma¬ 
jority of cases, these various alterations are especially apparent in 
the anterior parts, as the maxillary space, the throat, neck or 
chest. The parts between, and those posterior, are not, however, 
entirely free from them. Indeed they are sometimes more dis¬ 
eased than the anteriors. The heart is also diseased. The clots 
which it contains are always black and of little consistency. The 
endocardium is almost always ecchymotic and maculated with 
the coloring matter of the blood. The myocardium is soft and 
pale. The pericardium presents alterations analagous to those of 
the endocardium. They are also found in the serous membrane 
lining the blood vessels. The capillaries are gorged with blood 
and are sometimes upon large surfaces closed by true embolisms, 
due to the accumulation of the bacterides. The nervous appar¬ 
atus is also diseased. It offers lesions easily observed ; congestion 
and inflammation of the meninges, of the encephalic substance,Jand 
sometimes of the encephalo-rachidian axis almost in its whole 
length. Similar lesions are found in the lymphatics of the sym¬ 
pathetic system. The alterations of the viscera proper are not 
less numerous or remarkable. These organs, especially the liver, 
spleen and kidneys, are, in most cases, gorged with blood and 
softened. The spleen, especially in sheep and cattle, is ordinarily
