loss of flesh, capricious appetite, no cough, no nasal discharge, 
respirations normal. Examination per rectum revealed in the 
left flank an enormous tumor, as big as a man’s head, which 
was found to be a tuberculous growth of the spleen. A first in¬ 
jection of tuberculine gave a reaction of 2.8°. This was fol¬ 
lowed by three others, which gave respectively reactions of 
i.9°, i.6°, o.8°. After the fourth day polyuria then became 
manifest and lasted until death, which occurred after three 
weeks. At the autopsy lesions were found in the lungs, iden¬ 
tical to those of the first case. The abdominal organs con¬ 
tained only a few caseous tubercules in the liver and right 
kidney. The spleen weighed 7 kilos 250 grammes, and showed 
an enormous mass of chronic tuberculous lesions. In other 
words, in both cases lesions of acute miliary tuberculosis of the 
lungs were found, with chronic splenic alterations having cer¬ 
tainly existed a long time before those of the lungs .—(Annales

Incomplete Obstruction of Steno’s Duct [By M. Her- 
mans\.—Bn Irish horse presented on a level with the groove 
of the left lower maxillary bone a tumor, the size of a hen’s 
egg. Running from it in the direction of the parotid there is 
a hard cord. The tumor is movable, not painful, very hard in 
its centre ; and when it is displaced the hard cord, which is 
Steno’s duct, moves with it. The growth exists since some 
time, but has recently assumed larger dimensions ; yet the horse 
does not seem troubled by its presence. To all appearances it 
is a calculus and its removal is indicated. The horse is placed 
in stocks, the parts thoroughly disinfected, and a careful dissec¬ 
tion made over the course of the duct and over the tumor. The 
canal was then opened, expecting to see the calculus come out,, 
but, instead of it, by direct probing, it is discovered that a 
regular bony lining is protruding into the cavity of the canal, 
forming part of its walls. This bony envelope was then ex¬ 
tracted. The wound well cleaned, stitched, and covered with 
iodoformed collodion. The animal was not disturbed by the 
operation, continued to chew his food, and after two weeks the 
wound was entirely closed, leaving only a little thickening, 
which was relieved by frictions of ointment of iodide of potas¬ 
sium and extract of hemlock. As to the starting cause of the 
bony formation, the author thinks it was the result of a lesion 
of traumatic nature, probably a bruise against the manger.—
