body temperature from subcutaneous injection of 
eucalyptus oil also to be about 2 ® F. 
The action of eucalyptus oil in pyaemia and 
sepsis is discussed in the twelfth chapter. In 
diseases of the human organism, when produced 
by infection, the eucalyptus oil has proved its 
efficacy, though its action is circumscribed, as is 
the case more or less with all antiseptics. Siegen 
was one of the first who experimented with the 
eucalyptus oil for demonstrating its antipyretic 
action. [But the discovery of the value of 
eucalyptus foliage as affording remedies in fevers 
arose with Tristany and Trixidor in 1865.J 
Schulz made numerous comparative experiments 
on rabbits, brought into a fever state through the 
injection of putrid liquids from meat or decaying 
hay, and he was able, through counter-injection 
of the oil of eucalyptus, to reduce the temperature 
sometimes fully 4° F, in three hours. The appli- 
cation required from time to time to be repeated. 
In the 13th part, Schulz propounds his theory 
of the action of the eucalyptus oil, the following 
being the outline : — All terpens and their com- 
positions possess in a high degree the ability to 
attract oxygen and to form ozone, which again is 
readily given off on substances fit to undergo a 
higher stage of oxydation ; thus, on contact, any 
living cellules become more speedily and more 
strongly oxygenated. The oil, however, takes up 
again a new supply of oxygen from its surround-
