Mrs Simon, aged 20, had a burning fever, stifling of her breath, frequent vomiting and looseness, foul tongue, loss of sleep, restlessness, intermitting, low and irregular pulse. This terrible fever disappeared on the fourth day, and she thought herself recovered. But on the seventh day from her being taken ill the fever returned, she was light-headed, did not know her relatives, and was fevered in the highest degree. It looked like a malignant fever, but there were no spots. The following table shows the very high mortality from fever (as well as from smallpox) in the epidemic to which the above case belonged. _London: Weekly deaths from fever, smallpox and all causes._ 1710.
