EESULTING FROM DIFFERENT CAUSES. 155 



are seen. The oedematous spots on the skiu from the size 

 of a quarter of a dojlar to a saucer, the great weakness and 

 the ring-like swelling of the glans penis, the oedematous 

 swelling about the vulva extending to the udder, the vaginal 

 discharge, etc., diagnose the disease. 



4. Purpura Hoimorrlicujica. — Tlie more or less sharply 

 defined swelling of the skin or subcutis is so painful that 

 locomotion is materially interfered with, but the nature of 

 the swellings, the pet^^hiRe from millet seed to bean size in 

 the nasal mucous membrane, etc., suiBficiently define this 

 specific disease. 



5. Inflammatory Conditions of the Skin. — Especially when 

 the flexor surface of a joint, the hock and phalangeal articu- 

 lations are involved, as for instance, grease. The swelling 

 and pain cause lameness more or less marked, which almost 

 invariably loses itself after a few steps have been taken. 

 The local examination, revealing the fact that no other cause 

 is present to warrant lameness, is decisive. 



6. Shoulder Abscess, — Lameness occasionally follows this 

 condition, which is characterized by a sharply defined, hard 

 and somewhat painful tumor, varying in size, situated in or 

 beiow the mastoido-humeralis. 



7. Inflammatory Changes in the Mammary Glands. — This 

 induces the animal to show a straddling gait behind at times, 

 and the leg is quite often advanced in an outward swinging 

 fashion. The local examination reveals a painful state of 

 the gland. 



8. Inflammation of the Spermatic Cord and Testicles. — The 

 straddling gait l)ehind, with tendency to abduction of the 

 leg next to the diseased cord or testicle, is explained by 

 manual examination of the parts.
