TUBERCULOSIS OF THE IRIS AND CHOROIDITIS. 
A six-year-old cow that had calved four times failed to 
conceive again, and was put through a process of fattening. 
Toward the end of August she exhibited symptoms of an 
extended subacute conjunctivitis of a suppurative nature, ac¬ 
companied by great swelling of the lids, and with corneal 
opacity. The treatment was useless. 
By the beginning of October atrophy of the bulbus was 
present; the eye was contracted, hard and blind. About the 
middle of October the left eye became involved in the same 
piocess of destruction. On the ioth of December, the lacteal 
secretion appeared coagulated, and otherwise altered; on 
12th of December, the cow became very weak in the poste¬ 
rior limbs, and on the 16th of January she was utterly unable 
to rise from the reclining posture. All the symptoms of an 
acute metastatic arthritis were present in anterior and poste¬ 
rior extremities. 
Autopsy .—The left eye-bulb half as large as the right 
one ; cornea and vitreous humor of the same clouded ; in the 
parenchyma of the iris, and in the choroid coat, nodules the 
size of millet seed, composed of caseous contents. The right 
bulb nearly normal in size ; cornea opaque ; anterior cham¬ 
ber containing numerous white points; the vitreous body 
and lens transparent; upon the internal side of the iris a thin, 
fibrous coat; in the lungs caseous herds as large as a nut; 
mediastinal glands enlarged and caseous; in the synovial 
capsules abundant secretion; supra mammarian lymphatic 
glands hypertrophied. 
Diagnosis. — Pulmonary phthisis with parenchymatous 
mastitis, tuberculosis of iris, choroid coat and bulbus.—
