When Meunier's visit was approaching its conclusion, there happened an event which caused some excitement in our household, owing to the surprisingly strong effect it appeared to produce on Bertha--on Bertha, the self-possessed, who usually seemed inaccessible to feminine agitations, and did even her hate in a self-restrained hygienic manner. This event was the sudden severe illness of her maid, Mrs. Archer. I have reserved to this moment the mention of a circumstance which had forced itself on my notice shortly before Meunier's arrival, namely, that there had been some quarrel between Bertha and this maid, apparently during a visit to a distant family, in which she had accompanied her mistress. I had overheard Archer speaking in a tone of bitter insolence, which I should have thought an adequate reason for immediate dismissal. No dismissal followed; on the contrary, Bertha seemed to be silently putting up with personal inconveniences from the exhibitions of this woman's temper. I was the more astonished to observe that her illness seemed a cause of strong solicitude to Bertha; that she was at the bedside night and day, and would allow no one else to officiate as head-nurse. It happened that our family doctor was out on a holiday, an accident which made Meunier's presence in the house doubly welcome, and he apparently entered into the case with an interest which seemed so much stronger than the ordinary professional feeling, that one day when he had fallen into a long fit of silence after visiting her, I said to him-- "Is this a very peculiar case of disease, Meunier?" "No," he answered, "it is an attack of peritonitis, which will be fatal, but which does not differ physically from many other cases that have come under my observation. But I'll tell you what I have on my mind. I want to make an experiment on this woman, if you will give me permission. It can do her no harm--will give her no pain--for I shall not make it until life is extinct to all purposes of sensation. I want to try the effect of transfusing blood into her arteries after the heart has ceased to beat for some minutes. I have tried the experiment again and again with animals that have died of this disease, with astounding results, and I want to try it on a human subject. I have the small tubes necessary, in a case I have with me, and the rest of the apparatus could be prepared readily. I should use my own blood--take it from my own arm. This woman won't live through the night, I'm convinced, and I want you to promise me your assistance in making the experiment. I can't do without another hand, but it would perhaps not be well to call in a medical assistant from among your provincial doctors. A disagreeable foolish version of the thing might get abroad." "Have you spoken to my wife on the subject?" I said, "because she appears to be peculiarly sensitive about this woman: she has been a favourite maid."
