of the Axoido-atloid Joint , with Enlargement of the Right Lateral 
Muscles of the Neck. —A horse jumps an obstacle, falls and re¬ 
mains down as dead. Raised, his head is carried low down and 
deviated to the left; there is a very tender spot over the axoido- 
atloid articulation, which is very much swollen, and an enlarge¬ 
ment on the right side of the neck ; there is no crepitation. 
The treatment consisted of continued cold water irrigation, fol¬ 
lowed by gradual mechanical elevation of the head and neck, 
with a wide blister over the enlargement of the neck. The 
animal got well in five weeks. Laceration of the Means of At¬ 
tachment of the Sus-carpal ( Trepezium ) Bone. Also the result 
of a fall, this was characterized by a swelling of the external and 
posterior face of the knee, hot and painful. The sus-carpal bone 
is very movable and can be pushed to the posterior face of the 
knee/ No flexion at the joint. The horse resists energetically 
when it is attempted. . Cold water irrigations, compresses of 
tincture of arnica, followed by blistering and massage, with later 
on cauterization, gave good results. The animal was no longer 
fit for racing purposes. Laceration of the Internal Crural 
Muscles. —This occurred without external violence, on a flat 
field race, where the mare suddenly stopped. . Taken to her 
stall, she shows great suffering, is covered with perspiration, 
and unable to rest on the right hind leg. This is the seat, on 
its internal face, of an enormous swelling, fluctuating and ver\ 
painful. There is no crepitation. Cold applications were pre¬ 
scribed. By order of the owner the mare is destroyed on the third 
day. At the post-mortem is found a complete transversal lacera¬ 
tion of long and short adductors of the leg with a partial rupture 
of the pectineus and small adductor of the thigh. Fracture of 
the Scapula. —Like the preceding, this took place in a flat 
field race, the animal at her best speed suddenly stopped and 
is on three legs unable to rest on the right fore. She suffers 
greatly, she struggles whenever she is touched, there is a large 
swelling of the olecranian muscles and of the whole right sca¬ 
pular region. She was found dead the next day in her box. . A 
comminuted fracture (some twenty fragments) was found, which 
occupied the neck of the bone.— (Ibid.) 
Actinomycosis of the Rumen and Reticulum [Ay MM. 
Lienaux and Hamoir ] .—After a brief history of the etiology 
of actinomycosis and its comparatively contagious nature, where 
all manifestations of the disease seem to be due to the introduc¬ 
tion of the parasite through a trauma of some kind ; and after 
considering that these traumse may take place in the digestive
