Pregnant women are liable to be attacked with epidemic, endemic, and sporadic diseases. Eruptive fevers, etc., may attack parturient women, and if they do, the disease and labor in every case will have a reciprocal influence on each other—the disease will complicate the case. Influenza or intermittent fever may attack a woman at any period of gestation, and there may be no serious results. Cholera, small pox, typhoid fever, scarlet fever, measles, pneumonia, and jaundice are liable to cause abortion, and there is danger of fatal results, or either of them would be a dangerous complication at the time of labor. Syphilis would be a cause of abortion or premature labor, and any disease which allows the mother to carry the child the full term may reduce and weaken her. Glandular engorgements and scrofulous ulcers improve during gestation, but if the woman is suffering from a fracture, the bones will not unite very well. Tumors in the abdomen and pelvis may be an obstacle to delivery, and ulcerations of the cervix may also be harmful and protract the labor, as also may constipation, dropsy, and albuminuria. The latter may not be detected without an analysis of the urine, but dropsy will be obvious as soon as it exists. The evidences of tumors and ulcerations are found by palpation and the touch—sometimes by the use of the speculum. After learning the present appearance and the former history of the patient it may be necessary to examine further perhaps by palpation. By PALPATION we may sometimes (but not always) distinguish the head of the child, and perhaps tell to which side its back is turned. When making the examination let the patient lie on her back, make gentle pressure when the pains are off and the abdomen is relaxed; press the ends of your fingers above the body of the pubis; by pressing downwards you may perhaps feel the head if it has descended into the pelvis. You will need to press the abdomen carefully all over to ascertain if there are tumors, and also to ascertain if the body or some other part presents at the cervix uteri. If _auscultation_ is used we may determine positively the position of the fœtus by observing just where the sounds of the fœtal heart may be most plainly heard. The VAGINAL TOUCH is the usual mode of determining whether there is an unfavorable presentation of the child, as well as whether there is deformity of the pelvis, tumors in the vagina, ulcerations, &c.
