[12] The tortuous serpentine course which the arteries of the uterus take, is not, as has been generally supposed, a provision of nature against the increase of size which the uterus has to undergo during pregnancy, but is the result of the structure in which they ramify, having already undergone these changes during a previous pregnancy.

[14] The axis of the brim of the pelvis runs in such a direction, that if a line were drawn from its centre, it would pass upwards and forwards through the umbilicus: the gravid uterus has its axis rarely or never inclined less than this, and usually much more, especially in multiparæ in whom the fundus is occasionally inclined so strongly forwards as to receive the name of pendulous belly.
[15] We are inclined to think that the soft feel of the portio vaginalis is one of the earliest signs of pregnancy which can be detected by examination. Our attention was first drawn to it in an obscure case of early pregnancy, complicated with extensive disease, which we examined with Mr. Ingleby of Birmingham, and where we gave a wrong diagnosis, not considering the patient to be pregnant. If we had placed as much confidence in this symptom as we are now inclined to do, we should probably have formed a more correct view of the case. Since this we have, on several occasions, found that attending to this circumstance has considerably assisted us in determining cases of doubtful pregnancy at an early period.
[16] This description is given according to the lunar not calendar months, of which there are necessarily ten during the forty weeks of pregnancy.
