The increasing extent of the gravid uterus is well-illustrated in the Figs. 1, 3, 5, 8, 11, and 13, and the relationship [see column (9) of Table I] to the vertebral axis in Figs. 2, 4, 6, 7, 9, 10 and 12.
The weights of the unopened uterus and of the foetus alone are expressed as percentages of ewe weight (minus unopened uterus). Details are set down in columns (6) and (7) of Table I and a diagrammatic representation is given in the chart.
