The body of the uterus, when pressed between the two hands, will be found much larger than ordinary, and more round, and it will feel heavy when pushed up by the finger. In regard to the precise value of these probable signs, it can only be said, when they are observed, that it is certain that the womb is enlarged, and _most probably_ from pregnancy. But at the same time it must be remembered that several diseases, and particularly suppressed and irregular menstruation, or the development of tumors and polypi, will effect very similar changes, and that it is not _always_ possible to say whether they arise from these abnormal growths or from pregnancy, though it can generally be done. But though we cannot, in every case, say when these signs exist, that the female must be pregnant, we can nearly always say, when they do not exist, that she cannot be so, particularly if the other usual signs are absent. _End of the fourth month._--By this time the neck has become a little shorter still, and the mouth more open, but on the whole there is not much change to be felt internally. The body of the womb however, has now ascended above the superior strait of the Pelvis, and begins permanently to enlarge the Abdomen. It may be distinctly felt between the two hands, like a firm round ball, somewhat elastic, and resisting when pressed. This is the period when the motions of the fœtus are usually felt first, and these motions, with the ascension of the womb, are sometimes experienced very suddenly, so as to alarm the female, and produce certain curious sensations, with much nervous derangement. This is called _quickening_, and, with some persons, is always so well marked as to indicate not only their condition, but the very period, with great precision. Many however, never experience anything at all peculiar at this time.
