Under these circumstances, I believed I must treat him more for typhus than for scarlatina, and used cold baths; in which course I was encouraged by the fine reaction ensuing after every bath, and the slight clearing off of his mind for a few minutes. Internally, I used the muriatic-acid in the forms mentioned above (39), and the solution of chloride of lime, which was also used for a wash and sprinkled about the room. In order to draw the eruption towards the skin--provided there be any of the scarlatinous poison in his system,--I tried a few packs, but without avail. He grew weaker and weaker, though his skin continued to become red after every bath, and on the sixth day early in the morning, when we were about changing his linen, and I was holding him sitting up in bed, he expired in my arms. This is the only case of scarlet-fever, I lost under hydriatic treatment; and it is yet doubtful whether it can be considered as belonging to that disease. I have always considered it, and continue to do so now, a case of typhus, partly communicated by the typhoid exhalations of the other servant, and partly created in his own body, as he complained for more than a fortnight before, of nervous and feverish symptoms, which indicated a serious disease threatening him. The contagion of scarlatina may have made the case more dangerous by complicating it; but, be this as it may, it is certain that the symptoms were such from the beginning that a cure must have appeared most improbable at first sight to any physician of any school; and if there was a possibility of saving his life, it could only be done by the course I took; a course which had proved successful in several cases of typhus I had treated before, and which looked about as bad, and even worse than that of poor William McNought.
