![End of 8th month, the foetus is 15 -17 inches long. « 9th « « 16 -17^ 10th » 17^-18^ [According to Scliroeder.] American children are usually larger at birth- How soon can the sex of a child be recognized? Not certainly until during the fourth month. What is vernix caseosa ? An unctuous sebaceous secretion covering the skin of the child, for the purpose of lubricating it for delivery. It does not appear until the seventh month. What is meconium ? The dark green, semi-fluid contents of the fretal intestine, corresponding to fecal matter in the adult. It contains granular bodies, called meconium granules, the presence of which is characteristic of meconium. What changes occur in the womb itself during pregnancy ? It greatly enlarges, to accommodate the growing ovum, and at the end of pregnancy has a weight of two pounds, and its cavity is a foot in diameter. The cervix enlarges but little (not more than one-half), and its cavity remains separate until the last week or weeks of pregnancy, when the os internum is stretched open and the two cavities of the cervix and fundus become one. The tissue of the cervix becomes softer to the touch. What changes in position does the womb undergo? During the first month the increased weight of the uterus causes it to descend somewhat in the pelvis, or become prolapsed. End of 2d mo. Still low in the pelvis, and unusually anteverted. Bimanual touch shows it to be as large as a small orange. 3d The same, but as large as a child's head. 4th Fundus can be felt just above the symphysis, and being too large for the pelvis, it now ascends. 5th Fundus midway between umbilicus and symphysis. 6th at level of umbilicus. 7th 2 to 3', finger breadths above umbilicus. 8th 1 to 2 below en si form appendix. gth touches the 10th has descended to same position as in eighth month. Why does the fundus of the uterus descend during the last month? Because the cavity of the cervix is added to that of the fundus at that time, and the contents of the womb settle toward the pelvis, leaving more room above.](https://iiif.wellcomecollection.org/image/b21135514_0039.jp2/full/800%2C/0/default.jpg)
