It is within the
experience of many medical practitioners, that a patient, with strange
and unusual symptoms of disease, has been more distressed in mind, more
wretched, from the fact of being unintelligible to himself and others,
than from the pain or danger of the disease: nay, that the patient
has received the most solid comfort, and resumed a genial and enduring
cheerfulness, from some new symptom or product, that had at once
determined the name and nature of his complaint, and rendered it an
intelligible effect of an           cause: even though the discovery
did at the same moment preclude all hope of restoration.
