action of the affected muscles. There will also be rheumatism or neuralgia in other parts of the body or limbs ; the system will not be much disordered; the urine will be high colored, and deposit the lithates. 2. If from disease of the spinal column, the pain will be aggravated by percussion upon or along the sides of the spinous processes at this portion of the back, or by suddenly striking the toes against an uneven surface. There will be involuntary action of the muscles, especially of the flexors of the legs, diminished temperature, abnormal feelings, and more or less loss of power of the lower limbs. The spinous process of the affected vertebrae may possibly be projected, and this would confirm it. 3. If from a collection of matter in or about the psoas mus- cle, if unconnected with spinal disease, then the pain will be continuous, dull, and deep-seated; extending from the loins down the psoas, or in whatever direction the matter may have taken its course. The pain will be increased by flexion of the thigh, and there will be difficulty in walking; moreover, there will be marks of a strumous habit, and more or less symptoms of hectic fever. 4. If the " loin pain " originates in irregular hepatic function, then the pain will shoot upwards along the splanchnic nerves to the scapulae ; the alvine evacuations will show deficiency, alter- ation or excess of bile ; the urine will have a bilious tinge, there will be a congestion of the hemorrhoidal veins, and the spirits will be depressed. 5. If the " loin pain " arises from deranged duodenal function, then it will be noticed that about three or four hours after a meal, the pain will be aggravated, shooting through towards the right side of the abdomen, and continuing more or less until the food has passed from the duodenum into the jejunum. If this be the case, dyspeptic symptoms will prevail, and there will be likely to be painful pustules breaking out about the face. This last symptom, however, is not uniform, though frequent. 6. If the " loin pain " is from the kidneys, it will shoot down the course of the spermatic nerves, towards the round ligaments 35
