In the Days of the Comet by H.G. Wells

In the end my mother died rather suddenly, and her death came as a shock to me. Diagnosis was still very inadequate at that time. The doctors were, of course, fully alive to the incredible defects of their common training and were doing all they could to supply its deficiencies, but they were still extraordinarily ignorant. Some unintelligently observed factor of her illness came into play with her, and she became feverish and sank and died very quickly. I do not know what remedial measures were attempted. I hardly knew what was happening until the whole thing was over.
