the oil can still be perceived two or three days 
after a dose of it has been taken, also the fseces 
may give off the odor of eucalyptus for some 
time. No irritation is produced by the oil on the 
organs of digestion, a fact remarkable in contrast 
with the action of oil of turpentine. In reference 
to the effect of eucalyptus oil on the kidneys, it 
may be repeated that the urine assumes a violet 
odor after a large dose of the oil even for some 
days. The same effect is also produced by inha- 
lation or infriction of the oil, but secretion of 
unaltered oil, if any, with the urine is evidently 
small. Important is the observation that the 
kidneys themselves are not abnormally irritated 
by the passing of the oil. Sternberg affirms that 
albuminuria, if at all developed, shews itself not 
BO readily after the inhalation of eucalyptus oil as 
after the inhaling of oil of turpentine. 
The temperature of the human and animal 
body under the influence of eucalyptus oil is the 
topic of the eleventh chapter. Gimbert was the 
first to shew that the internal use of eucalyptus 
oil decreases the temperature of the human body. 
Siegen found that 100 drops of eucalyptol taken 
in the course of an afternoon were able to reduce 
the normal temperature nearly or fully 2^ F. 
Purified eucalyptus oil administered to rabbits by 
Schulz lessened also the temperature of these 
animals in a marked manner. Professor Siegen 
furthermore found the reduction of the ordinary
