solution can doubtless be applied under impervi-

on wounds, whether — according to requirement — 
it is applied directly, then even causing no pain, 
or whether mixed with much water, to moisten 
compresses and bandages, or to irrigate the 
cavities of wounds,

carbolic acid, is not poisonous, and can therefore 
be administered even in large doses internally. 
6. Eucalyptus oil can therefore be employed 
with impunity, when any risk is foreseen in the 
use of carbolic acid; thus in the treatment of 
youthful individuals and of exceedingly debilitated 
patients, also in cases where large spaces of 
wounds lead to great resorption from without; 
while also an excessive quantity of the ad- 
ministered oil can never be followed by such 
serious consequences, as in the case of carbolic 
acid. 
Lately, also, Dr. A. W. Mayo Robson, of Leeds,

acid spray, has used, in various surgical operations, 
currents of air wafting over eucalyptol or cajuput 
oil or oil of peppermint for antiseptic effects,
