Well has the celebrated Mauriceau observed, "S'il y a occasion où le chirurgien doive faire plus grande reflexion, et apporter plus de précaution aux choses qui concernent son art, c'est en celle où il s'agit de juger si l'enfant qui est dans la matrice est vivant, ou bien s'il est mort." There are few circumstances more painful to the feelings of an accoucheur, than the uncertainty as to whether the child be alive or dead, in a labour where the passage of the head is rendered unusually difficult or dangerous for the mother, even with the aid of the forceps; whether the difficulty be produced by want of proportion between the head and pelvis, unusual rigidity of the os uteri, &c. Could he assure himself that it was alive, he would feel justified in either trusting still longer to the efforts of nature, or in applying the forceps, even although he knows that the delivery cannot be effected without considerable difficulty and suffering: whereas, if he could once feel satisfied that the child had ceased to exist, he would have recourse to perforation, for the purpose of diminishing the size of the head, and thus releasing the mother from the dangers of her situation. The increasing success which has attended the Cæsarean operation of late years, adds still more to the importance of having the signs of the child's life or death in utero carefully investigated and understood; for, under such circumstances, it becomes a most serious question whether we are always justified in destroying the life of the foetus by perforation, when we might in all probability have saved it by resorting to another means of delivery, which, formidable as it is, is now infinitely less so than it was in former times. It becomes a question whether we ought not, in certain cases to adopt the same indications for performing the Cæsarian operation, as are used upon the Continent, and apply it not only to those cases where the child cannot be delivered _par vias naturales_, but also in those cases of minor pelvic obstruction, where, if we could feel sure of the child's death, we should have recourse to perforation. Under circumstances of this nature, the question becomes one of fearful responsibility, the painfulness of which is not a little increased by the uncertainty as to whether the child be alive or not. Mauriceau was the first author who devoted a chapter expressly to the consideration of this subject, and those few who have done the same since his time, have borrowed largely from his observations. A great number of symptoms have been enumerated as indicating the child's death in utero, but for the most part they are deserving of very little confidence, frequently occurring where the result of labour has shown the child to be alive and strong, or _vice versâ_. The most practical arrangement of these symptoms will, we think, be under the two following heads: those which occur _before_ labour, and those which occur _during_ labour.
