Upon the above principles I have treated the vesicle of vaccination, with much comfort to the patient, and in most of the cases entirely prevented the pustular stage.

APPENDIX D.
THE CLINICAL THERMOMETER.
The possession of a self-registering Clinical Thermometer in every household, in a tropical or malarious climate is a necessity, more especially when at a distance from medical aid. It is a means for assisting to ascertain most accurately, in a very few minutes, whether a child or patient is really ill, and the necessity there might be for the administration of remedies; for calling in other and more proficient assistance; or to allay anxiety that might have accrued from a nervous fear, when possibly no actual illness existed.
From one single observation of an abnormal temperature, we learn:
"1. That the patient is really bodily ill.
"2. When there is considerable elevation of temperature, we know that there is fever.
"3. When there are extremes of temperature, we know that there is great danger.
"The mean normal temperature of the human body in health is 98·6° Fahrenheit's scale."[5] This may vary in health, in exceptional cases from 97·5° to 99·5° Fahrenheit.
