I may add that it is black, with the first two abdominal segments, the legs and the tarsi a rusty red. Clad in the same livery and much smaller than the female, the male is remarkable for his eyes, which are of a beautiful lemon-yellow when he is alive. The length is nearly half an inch for the female and a little more than half this for the male.
The patient is inclined to attribute the pain and stiffness to exposure to cold or rheumatism. At an early stage the diaphragm and the muscles of the anterior abdominal wall become contracted; later the muscles of the back and thorax are involved; and lastly those of the limbs. Although this is the typical order of involvement of the different groups of muscles, it is not always adhered to.
Osiander speaks of an abdominal fetus being taken out alive, and there is a similar case on record in the early part of this century.
Just as the larynx, the ear, the nose, the sole of the foot, and the skin have all developed the specific type of nociceptors which are adapted for their specific protective purposes, and which, when adequately stimulated, respond in a specific manner in accordance with the law of phylogenetic association, so, the abdominal viscera have developed equally specific nociceptors as a protection against specific nocuous influences.
As the abdomen becomes stronger, raise both legs at once, keeping knees straight. It is important that the legs be lowered slowly. For exercising the abdominal muscles and strengthening the pelvic organs. This and the following exercise are especially valuable for remedying female troubles: Lie flat on back, arms folded on chest. Place the feet under a chair or bed to keep them in position.
As all the symptoms in this case were abdominal, it was supposed that during an epileptic seizure this girl had swallowed the needles; but as she was of an hysteric nature it seems more likely they had entered the body through the skin. There is an instance in which 132 needles were extracted from a young lady's person.
Most species have on the eighth abdominal segment a rather long breathing-tube the tip of which is thrust just above the surface of the water when they come up for air.
The diaphragm is the dome shaped breathing muscle which serves as a partition between the chest and abdominal organs. Its contraction causes development of the lungs and heart and at the same time the internal massage of the abdominal organs. The lungs have been called the scavengers of the body for they take off poison which would kill us.
The legs consist of six joints, the tarsal joints being large and two in number, and bearing a pair of terminal curved claws. The three thoracic segments are of nearly equal size, and the eight abdominal segments are also of similar size. The tracheæ are well developed, and may be readily seen in the legs. They may probably be directly compared with the abdominal legs of Myriopods.
Longhi describes the case of a woman of twenty-seven, an epileptic, with metritis and copious catamenia twice a month. She was immoderately addicted to drink and sexual indulgence, and in February, 1835, her menses ceased. On May 8th she was admitted to the hospital with a severe epileptic convulsion, and until the 18th remained in a febrile condition, with abdominal tenderness, etc.
