EUCALYPTUS SALMONOPHLOIA. 



nnmerous experiments in 1874 we know, how far the oil is exercising a retarding influence on the 

 action of the heart and the circulation. Similarly the oil produces a reduced vitality of the spinal 

 column, and the brain is brought by it into a less active state. Small animals become paralyzed 

 from merely inhaling Eucalyptus-oil, as we learnt already from Gimbert. To demonstrate, to what 

 extent the reflex-irritability can be reduced by Eucalyptus-oil, Dr. Grisar in 1873 was able to 

 counteract with it completely the effect of brucin. 



Very long ago Professor Eudolphi spoke of the anthelmintic value of Oajuput-oil ; similarly 

 Professors Siegen and Vidan found Eacalyptus-oil to possess vermifagal properties ; and this has 

 been confirmed by independent observations of Professor Schulz ; but the efforts to annihilate 

 Trichina spiralis in rabbits by this oil proved fiitile. Crawfishes placed in water, containing only 

 ^ per cent, of Eucalyptus-oil, succumbed in five hours as noticed by Dr. Hugo Schulz, who also 

 found that cockroaches, bees and many other insects perished from slight inhalation of this oil in 

 a short time. Carps placed in water, mixed with only | per cent, of Eucalyptus-oil, died in five 

 minutes.
