with a feeling of tremiilency, and considerable 
depression of the system, but no impairment of 
the appetite, no particular alteration of the 
diuresis, beyond odor of eucalyptus. The cutane- 
ous exhalations were more of the odor of 
trimethylamin. In a second experiment, 
drachm of eucalyptol were taken within 2^ 
hours, causing no disturbance in the digestion, 
but calling forth a general apathy. In the ex- 
piratory secretions, eucalyptol was perceptible for 
14 hours, and the urine shewed the presence of 
the oil for fully 40 hours. Professor Schulz took 
for a whole month, every morning, 20 drops of 
eucalyptus oil (best refined) mixed with some 
milk before breakfast ; as in the operation of oil 
of turpentine, eructation set in for some days, but 
ceased afterwards. The urine, when warmed, 
gave off violet odor, but shewed no albumen 
exhalations of eucalyptus odor were perceptible, 
but no disturbance in the digestion ; the appetite 
remained good ; the evacuations continued nor- 
mal ; no polyuria occurred. Large doses, from 2 to 
drachms, taken singly did not affect, hurtfully, 
the digestion, but a feeling of lassitude and some 
slight nausea set in, passing, however, in half a 
day. Experiments were made by Professor 
Schulz, both with the raw and with the refined oil of 
eucalyptus, to test their respective effect as an 
external application. The burning sensation 
caused by one day’s application of the raw oil of
