will be found that the fasciculi of certain sets of muscles have under- 

 gone fatty (1 exoneration to a more or los extent. The superficial 

 Iving lymph-elands may be enlarged and infiltrated, on section 

 fluid of a yellow colour may be seen to escape. The pleural 

 cavities according to the symptoms and complications present may 

 be free or contain blood-stained fluid in considerable quantities. 

 The lunge, with the exception of presenting a certain amount of 

 emphysema at the apices, in uncomplicated cases only present a few 

 sub -pleural ecchymoses. The pericardial sac usually contains a cer- 

 tain quantity of fluid which varies in character and amount in 

 different cases. The heart is frequently hypertrophied, the base 

 the seat of a yellow-coloured deposit, gelatinous in character, which 

 takes the place of the usual fat. The base of the organ is some- 

 times dotted over with small ecchymoses dark, red or purple in 

 colour, which, as in Surra, lie under the visceral pericardium singly 

 or in groups. The wall of the left ventricle is hypertrophied, and in 

 a minority of cases subendocardial extravasations are present in 

 the left ventricle. The liver is frequently enlarged, 11- to 18 Ibs. 

 in weight, and, on section, found to be somewhat engorged with 

 blood. The spleen is always enlarged to a greater or less decree, 

 2*5 to 6 lb=. in weight and the capsule dotted over with red-brick- 

 coloured ecch ymoses. The tissues are, as a rule, firm and, on sec- 

 tion, are found to be dark in colour. The kidneys are generally 

 much increased in size, pale and petechiated, and the hilum filled 

 with jrelatinous exudation. The fetticles may be hypertrophied or 

 atrophied, and in some cases appear not to be affected at all, but it 

 is not infrequent to find that the tunica vaginalis and propria are 

 adherent. The tissues of the spermatic cord and epididymis may 

 also be infiltrated and thickened. In the mare, the m. m. of the 

 vagina may be either normal in appearance or of an orange 

 colour, the capillaries injected and arborescent in their distribution, 

 or the lining membranes of the vagina and uterus may be 

 thickened and the former present dark red coloured nodules on its 

 surface, resembling the common variety of sea-anemone. The 

 changes observable in the nervous system vary considerably ac- 

 cording to the period of the disease which has been reached at the 

 time of death, and the length of persi3tence of the respective
