Note 53 — Chapter IX · ON POISONS, MIASMS AND CONTAGIONS.
Reading edition
Ozone is said to oxidize the poison. It destroys sulphuretted hydrogen and all oxydable miasms, and is the most powerful disinfecting agent, but is itself unfit for respiration: it causes suffocation. Air in its normal state contains one ten-thousandth part of ozone; when raised to one two-thousandth part it is sufficient to kill small animals.
