MYOSITIS, 271 
on partial sclerosis of the muscle; there often remains a local stiffness and 
sometimes a lameness. 
To this myositis of casting may. be added that of long-continued use of 
the muscles and of overwork—-myositis by overwork. Myositis of the 
brachial biceps is quite frequent (Gerlach, Giinther). It is ordinarily ob- 
served in light draught or saddle horses after a quick and long trot. It 
is indicated by a lameness resembling that due to the inflammation of 
the tendon of this muscle and of its sheath over the bicipital groove, viz., 
an abnormal sensibility of the muscle and acute pains with the slightest 
pressure. Rest, revulsives and massage almost always bring on rapid re- 
covery. Friction with a solution of ichthyol, 5 per cent., combined with 
massage, are peculiarly advantageous (Hoffmann). During warm weather 
Rey has often observed muscular inflammations limited to the muscles of 
the shoulder, to the dorsal region, or the croup. There occurred in those 
parts enlargements neatly circumscribed to certain of the muscles. 
* Puncture gave issue to a darkish blood, followed by a small quantity of 
reddish serosity.” Out of ten subjects treated, resolution followed 
naturally or with the use of resolutives. ‘ Among the modes of treat- 
ment used, the most efficient consisted in mustard frictions over the 
tumefied parts, which were almost always followed by diminution of the 
muscular swelling. Bleeding was performed also on some plethoric sub- 
jects.” In market cattle obliged to take long walks before being slaugh- 
tered, tumefaction of certain groups of muscles and granular degenera- 
tion of those organs are frequently observed. These lesions give rise 
to a lameness more marked when the animal is cold; the affected region 
is warm and painful. In such cases Furlanetto has often found the sub- 
cutaneous connective tissue of the shoulder, arm, forearm, or of the in- 
ternal face of the leg, infiltrated with bloody serosity; the muscles of the 
various regions being infiltrated, they are soft and darker in color than 
in the normal state. When the lameness is located in the hind leg the 
same alterations are observed in the muscles of the thigh. Similar ac- 
cidents have been noticed in sheep andswine. The prophylaxis of this last 
variety of myositis is indicated by the etiology : that is, not to demand of 
the animals too tiresome or too long walks. As to the curative treatment, - 
it consists of rest, local cold application, massage, resolutive frictions and 
alkaline salts in the drinks of the patient. 
Rheumatismal myositis has been especially observed in horses, cattle 
and dogs, sometimes in sheep and swine. The muscles of the neck, 
shoulder, thigh and loins are more ordinarily affected. Several authors 
have related cases of muscular rheumatism more or less generalized in 
horses. The acute pain, its increase by pressure or motion, the absence 
of well-marked inflammatory phenomena, the erratic character of the
