Page 11 - I have found to correspond in the main to the line of the ureters. Along this line they have the following relations to the pelvic brim (in the recent state) : At the bifurcation, half an inch below ; at the extremities of the transverse diameter of the pelvis, about an inch ; and at the spine of the pubes, two inches below. As a whole, the tubes in the pelvis are situated upon a higher plane than in the non-pregnant condition, having been carried slightly upward while being separated from their...
Page 11 - Reaching the bony brim (the ilio-pectineal line), they leave the pelvic wall, emerging from beneath the base of the broad ligaments (in pregnancy about on a level with the pelvic brim, and carried back on a line with the synchondrosis), and take a course downward, forward, and somewhat inward, passing about midway between the pelvic wall and the cervico-vaginal junction, but approaching very closely the antero-lateral wall of the vagina, as they turn more decidedly inward, on a lower plane, to strike...
Page 3 - One is the simple portrait, in which the object is represented exactly as it was seen ; the other is a representation of the object under such circumstances as were not actually seen, but conceived in the imagination.

Page 98 - ... separation, and that this may be either rather less or rather more than one-half of its area before labour had begun, are anatomical facts, but not nearly so significant as the following one that with this amount of retraction the uterine wall embraces the placenta all round. In other words, the placenta has not become separated before the uterus begins to act on it as a whole. When this has taken place, the operating force is no longer retraction of the site alone, but retraction of the...
Page 3 - Hence, he continues, he has succeeded in producing an image that "represents what was actually seen, it carries the mark of truth, and becomes almost as infallible as the object itself.
Page 12 - The softening of the cervix uteri, already commenced superficially during the menstruation preceding conception, continues and extends more deeply into the substance of the cervix as pregnancy advances ; and the process is generally completed two or three months before the end of utero-gestation.
Page 48 - The placenta is situated in the anterior wall, rather more to the left than to the right of the middle line. PL. II. BEGINNING OF FIKST STAGE, from the Axial Coronal Section in PI. VI. of the Author's "Atlas of the Anatomy of Labour etc!
Page 11 - A line drawn from the bifurcation of the common iliac to the spine of the pubic bone corresponds in the main to the line of the ureters. Along this line they have the following relations to the pelvic brim (in the recent state). At the bifurcation, half an inch below, at the extremities of the transverse diameter of the pelvis, about an inch ; and at the spine of the pubic...
Page 11 - ... bifurcation, the left just behind, the right just in front of that point, they descend into the canal to the brim of the bony pelvis, the point being about the synchondrosis. In this course they accompany the internal iliac artery, the right in front of the vessel, the left crossing it obliquely. Reaching the bony brim (the ilio-pectineal line), they leave the pelvic wall, emerging from beneath the base of the broad ligaments (in pregnancy about on a level with the pelvic brim, and carried back...
