decay, the muscular fibres, after 20 days, not 
becoming dissolved, while in a one half per cent, 
quinine solution it became putnd in four days. 
(Some similar results were obtained in the 
writer’s own laboratory as long ago as 1866, in 
comparison to the action of carbolic acid, but re- 
mained unpublished.) Dr. Schmid found meat, 
immersed for a year in undiluted eucalyptus oil, 
to become almost horny, probably from coagula- 
tion of the muscular protoplasm. 
Siegen observed that one part of eucalyptol 
was sufficient to keep 300 parts of blood for 
10 days from putrefaction, while in the same time 
unmixed blood completely decomposed. Solu- 
tions of tannin and tartaric acid, to which 
eucalyptol was added, remained perfectly clear, 
whereas otherwise they became mouldy. Mees 
also demonstrated the highly antiseptic power of 
eucalyptol long ago, but found for his experi- 
ments stronger proportions needful than Siegen 
and Binz. 
L. Bnchholtz* ascertained that one part of 
eucalyptol in 666 parts of fluids was sufficient to 
prevent the development of bacteria, whereas of 
quinine and carbolic acid, one part in 200 was 
needed for the same purpose. So also Schulz 
found that one part of refined eucalyptus oil 
added to 10,000 parts of water, preserved fresh 
fibrin for 10 days from development of bacteria,
