mes daily. The composition of the powder should be such as
to permit of its liberal use, thereby affording mechanical protection to
the wound as well as exerting a desiccative effect. Equal parts of boric
acid and exsiccated alum serve very well in such cases.

Animals suffering from open joints of this kind should be confined in a
standing position, preferably in slings, and kept so confined for three
or four weeks. Since they usually bear weight upon the affected member,
there is no danger of laminitis resulting.

Luxation of the Scapulohumeral Joint.

Because of the large humeral head articulating as it does with a
glenoid cavity, scapulohumeral luxations are very rare in the horse.
According to Moller[7], luxation is generally due to excessive flexion
of the scapulohumeral joint. In such cases the head of the humerus is
displaced anterior to the articular portion of the scapula and remains
so fixed.

Symptoms.--Complete luxation of the scapula is recognized because of
immobility of the scapulohumeral joint and of the abnormal position of
the head of the humerus, which can be recognized by palpation, unless
the swelling be excessive. Immobility of the scapulohumeral joint is
noticeable when one attempts to passively move the parts.

Treatment.--Reduction of the luxation is effected by making use of the
same general principles that are employed in the reduction of all
luxations, and they are--the control of the animal so that the
manipulations of the operator are not antagonized by muscular
contraction, which is best accomplished by anesthesia; placing the
luxated bones in the position which they have taken to become unjointed;
and then making use of force which is directed in a manner opposite to
that which has effected the luxation.

In a forward luxation of this kind, the operator should further flex the
humerus, and while it is in this flexed position, force is exerted upon
the articular head of this bone, and it is pushed downward and backward
into its normal position.

After-care consists in restriction of exercise and, if necessary,
confining the subject in a sling and the application of a vesicant over
the scapulohumeral region.

Inflammation of the Bicipital Bursa.
(Bursitis Intertubercularis.)

Anatomy.--There is interposed between the tendon of the biceps brachii
(flexor brachii) and the intertubercular or bicipital groove a heavy
cartilaginous pad, which is a part of the bursa of the biceps
