One can only repeat, what indeed Le Fort states, that in these most important points of enquiry, the very elements are yet wanting to us. Some hospitals have rather plumed themselves on their humanity in giving shelter to poor lying-in women as long as possible, while in military lying-in hospitals soldiers’ wives are obliged to go home as soon as they can, to help the domestic earnings. In the first class the death-rate is high, in the last it is low. The low death-rates in workhouse lying-in wards appear to support this conclusion also. These do not retain together women not yet in labour, women in labour, women delivered, and convalescent women. Their principle, on the contrary, is to receive women when labour is imminent, and to send them out of the ward as speedily as possible. A moment’s consideration will be sufficient to show how important a point in management this is. If there is any danger at all to puerperal women in a lying-in institution (a fact which has been proved), is it not clear that the danger must become cumulative? It will increase in a certain ratio as the length of residence increases. Blood-poisoning, if once begun, will not stop of itself unless the subject of it be removed from the cause, or the cause from the subject, if it stop even then. To retain both subject and cause together is simply to render certain that which under better management might have been evanescent. The more this question is considered the more important does it appear, as involving an element exercising a very considerable influence on the ultimate fate of inmates of lying-in institutions. The institution, by retaining its inmates, becomes a hospital; and, as such, subjects its inmates to hospital influences while in the most susceptible of all conditions. The absence of information in almost all published statistics on the point would be grotesque, if it were not alarming from the carelessness it shows. With some difficulty the following few meagre data have been scraped together as to the average number of days lying-in women spend in the undermentioned institutions:— Soldiers’ Wives’ Hospitals 10 to 12 days Liverpool Workhouse Lying-in Wards 14 „ London Workhouse Lying-in Wards 14, 18, 21 „ Paris Maternité 17, 18 „ Paris Clinique 18, 20 „ King’s College Hospital 16 „ This involves the question of management, which is next to be considered. _EFFECT OF GOOD MANAGEMENT ON THE SUCCESS OF LYING-IN ESTABLISHMENTS._
