The want of a national register of still births is one of the causes which in this country interfere with such important inquiries as those that relate to the true mortality due to parturition. No doubt our system of registration of live births is sufficiently perfect; but until a corresponding record of still births is available, it will be impossible to ascertain, with the accuracy necessary for statistical purposes, the number of women who have, within a given period, become mothers. This is the more to be regretted, since the danger to the life of a female is likely to be far greater when she has given birth to a dead child, than when by her labour she has added a unit to the living population of the country.
