6. _Condition of the Cervix Uteri._--The cervix softens during pregnancy, and the softening is present as early as the second or third week. It is an important sign. Hejar‘s sign or the softening at the junction of cervix and body and the lower uterine segment is valuable, but not always easily elicited. It is of most value from the second to the fifth months. At the sixth month it loses one-fourth of its length; at the seventh it is only half of its original length; at the eighth it loses another quarter; and at the ninth the neck is entirely obliterated. This shortening is more apparent than real, and its occurrence is denied by the late Dr. J. M. Duncan, except during the last few days of pregnancy. 7. _Quickening._--The period at which quickening occurs varies from the fourth to the fifth month; and the term is understood to imply the first perception of the movements of the fœtus experienced by the mother. Nervous women, anxious to have children, sometimes complain of sensations which they ascribe to quickening, pregnancy being absent. Pregnancy may occur without quickening. 8. _Kiesteine._--This is no test of pregnancy, as it may be found in women not pregnant. 9. _Jacquemier‘s Test._--A violet or port-wine colour of the vagina and inner surface of the vulva, due to venous congestion of the parts from pressure of the gravid uterus. A flattening of the upper wall of the vagina, produced by the enlargement and anteversion of the uterus, which, forcing the os towards the sacrum, makes the anterior wall of the vagina tense, has been added by Dr. Barnes as a sign of pregnancy. Certain Signs 1. _Ballottement._--This test of pregnancy is applied by causing the patient to stand upright; the finger of the right hand is then passed into the vagina and placed in the anterior fornix, the other hand being placed lightly over the abdomen in order to steady the uterine tumour. If the finger be now jerked upwards against the head of the child, it will be felt to float upwards in the liquor amnii, and then by its own weight gradually to return to its former position. Tumours in the uterus, attached to its walls by a pedicle, may give the same sensation. Scanty supply of liquor amnii, or malposition of the child, may sometimes prevent the adoption of the test. 2. _Uterine Souffle._--Under this head are included the placental bruit, and the pulsations of the umbilical cord. Both these sounds require a skilled auscultator to detect them. The uterine murmur, or _bruit placentaire_, is heard best at the lower and lateral portions of the uterus, just above Poupart‘s ligament. It is isochronous with the pulse of the mother, and is heard most distinctly about the fourth or fifth month of utero-gestation; in some cases, however, it may be heard as early as the tenth week. The sound is intermittent, and varies in character, being sometimes hissing, whirring, or cooing, at others rasping.
