eucalyptus globulus, under exclusion of the 
atmospheric air, was much like that produced by 
a sinapism; the skin had become diffusely 
reddened with simultaneous development of 
numerous pustules filled with yellowish serum. 
These appearances diminished slowly, and even 
after seventeen days, vestiges of the application 
could be observed in cutaneous exfoliation ; the 
urine emitted, after two days, still an odor of 
violets. On application of the purified oil of 
eucalyptus globulus externally, the smell arising 
was much less intense than from the raw oil, the 
burning sensation on the skin was much less ex- 
perienced ; but miliary pustules, sudamen-like, 
appeared also. Two weeks after these experi- 
ments arose on the chest a reddish exanthema, 
which spread to the back and loins, and developed 
copious pustules, comparable to those of acne ; 
but this eruption was not accompanied by itching, 
the pustules were grouped orbicularly, and in this 
manner followed each other. Notwithstanding 
the use of tepid baths, this complex of appear- 
ances lasted for four weeks, and terminated in 
decrease of rubescence, exsiccation of the pustules, 
and desquamation of the cutis. 
The tenth part of the essay refers to the secre- 
tion of the eucalyptus oil through the intestines 
and kidneys. Eucalyptus oil is able to maintain 
itself for some time undecomposed in the human 
constitution. In the_ expiratory air the odor of
