EXTRACTS FROM FOREIGN JOURNALS. 
several centimetres thick, hard and tense, neither warm or pain¬ 
ful on pressure. The skin covering it is free from injury and with¬ 
out external marks of irritation. There is a little swelling under 
the sub-glossal space. The jugulars are swollen and give to the 
linger the sensation of a hard liquid column, no venous pulse. 
The auscultation of the heart shows less strength and more fre¬ 
quency in the beatings, though no irregularity in the cardiac con¬ 
tractions. Not able to feel the pulse at the carotid ; at the glosso 
facial it is frequent, small and soft, but very regular. The con¬ 
junctiva; are slightly injected. The percussion of the chest gives 
a normal resonance all over and does not show the slightest in¬ 
crease of sensibility even in the cardiac region. By auscultation, 
the respiratory murmur is heard on both sides, but somewhat 
weaker ; auscultation of the trachea shows, on the contrary, an 
increase in the laryngo-trachal sound ; but no pathological sounds 
otherwise. Respiration is regular, slow and quick. There is no 
cough, but frequent eructuations; slight tympanitis—appetite 
diminished, though the animal eats yet some bran and oats. She 
drinks with pleasure milk or barley flour water. Rumination 
irregular, foeces frequent and natural. The animal keeps the 
standing position, her neck stretched out, with head extended and 
somewhat elevated. She dislikes to move, and when she does, 
her respiration becomes deep and difficult. 
At the post mortem an enormous tumor was found situated 
under the inferior face of the trachea—partly out of the chest, 
partly in it. It is the thymus gland, weighing 3 kilogrammes 
and 600 grammes. It is lobulated, and of a paler color than the 
normal gland, though red, firm and harder. The lobules are 
united together by condensed cellular tissue, adherent to the 
trachea; it envelops the anterior aorta and its branches, the 
anterior vena cava, the oesophagus, pneumo gastric nerves, etc., 
etc.,—in fact, all the organs contained in the anterior mediasti¬ 
num. Numerous sections exhibit several softened points, round, 
well defined, varying in size from that of a nut to that of an egg ; 
these are formed of softened substance, and are of a blackish 
color ; some contain yellowish, small spots. In the anterior part 
of the chest, the costal pleura offers on its free surface a yellow-
