Dr. Le Fort has stated that puerperal fever cases had been retained temporarily in the wards after the development of the disease; that the same nurses took charge, not only of cases of disease in the isolated wards, but also of women making healthy recoveries; and that there is nothing to prevent the medical attendant passing almost directly from the autopsy of a puerperal fever case to render assistance to a healthy woman. This experience is very important. It shows how much the safety of lying-in hospitals depends on common-sense management, and that it would be disastrous to trust to improved construction alone, while everything else is left to take its own course. We now arrive at the consideration of an elementary point:— _SHOULD MEDICAL STUDENTS BE ADMITTED TO LYING-IN HOSPITAL PRACTICE?_ This is a very grave question. Medical students were admitted to the lying-in wards at King’s College Hospital. Was this one cause of the occurrence of puerperal diseases there? There are facts, it is true, such as those supplied by the Maternité and Clinique at Paris (the latter only admitting medical students), in both of which establishments the mortality is excessive, which on first sight appear to show that the presence of medical students in a lying-in hospital is not necessarily a cause of adding to a mortality already excessive. But on the other hand there are facts, such as those given by Dr. Le Fort, admitting of a comparison being made between the mortality in lying-in wards to which medical students are admitted with the mortality in other wards of the same establishment not admitting students, which appear to establish the point conclusively. The special case he cites is the following:— At Vienna there are two lying-in cliniques, one for students and one for midwives. They are both situated in the same hospital, and their external conditions are insufficient in themselves to explain the facts now to be noted. Puerperal fever prevailed in the hospital during the same months in ten separate years, from 1838 to 1862, and the following table gives the mortality per 1,000 in each set of clinical wards:—
