increased excitementj and nuich secretion of 
mucus. Among fishes, large specimens of the 
leuciscus dabula of the carp trihe, when placed in 
big yessels filled with water containing | per 
cent, of eucalyptus oil, fell aside already in two 
minutes, under symptoms of dyspnoea, and died in 
five minutes ; in water mixed with only per 
cent, after first violently moving about, they 
dropped aside in minutes with much working 
of the gills, then became paralysed, and died in 
20 minutes. The dyspnoea symptoms are ex- 
plained by the withdrawal of the oxygen of such 
air, as is contained in water, through the widely 
distributed particles of the oil. 
The ninth chapter of Dr. Schulz’s essay refers 
to the internal and external action of eucalyptus 
oil on man. Professor Giinbert, who first ex- 
perimented on the physiologic effect of the 
eucalyptol, found already, that 24 drops taken 
internally produced a pulsation of 80, and a body 
temperature of 99 deg. P.; the urine assumed a 
violet odor, much sleepiness was experienced 
after five hours ; subsequently 8 to 10 drops of 
the oil taken daily caused no ill effect of any kind. 
80 drops administered in two doses within half 
an hour produced heat of the fauces, warmth in 
the stomachic region, also eructation, cephalalgia, 
and then calm sleep. Siegen took nearly a 
drachm of eucalyptol within five hours, divided 
into five doses ; the effect of this was drowsiness.
