city horses, more frequent than is generally supposed.

Pathological Anatomy.--More or less destruction of the cartilaginous
portion of the bursa, sometimes involving the tendinous portion of the
biceps, takes place and, according to Moller, in some instances there
occurs ossification of the tendon. Autopsies in some old horses reveal
the presence of erosions of cartilage and hyperthrophy of the inflamed
parts.

Symptoms.--In acute inflammations, there is always marked lameness.
This is manifested to a greater degree when the subject advances the
affected leg. There is incomplete advancement of the member; the toe is
dragged when the horse is made to walk and the foot kept in a position
posterior to the opposite or weight bearing foot while the subject is at
rest. Lameness is disproportionate to the amount of local manifestation
in the way of heat, swelling and pain that is to be recognized on
palpation. In fact, in some cases so much pain attends the condition
that no weight is borne by the affected member, and when compelled to
walk, the subject hops on the sound leg.

Chronic inflammation of the bicipital bursa is occasionally met with
wherein both members are affected. Because of the nature of the
structures involved, when inflamed, chronic inflammation is a more
frequent termination than is complete recovery. Bilateral affections are
seen in horses that are driven for years, regularly at a fast pace on
paved streets. In such cases, the gait is stilted, that is, there is
incomplete advancement of both members and, of course, the period of
weight bearing is correspondingly shortened; hence the short strides.

In chronic cases, little if any evidence of inflammation is to be
