Book excerpt: Excerpt from The Dental Times, 1869, Vol. 6: A Quarterly Journal of Dental Science To prepare protoxide of nitrogen for inhalation, then, great care must be taken to preserve its purity; consequently it becomes important to maintain, as nearly as possible, an equal temperature during the process of its manufacture, and, should any nitric oxide to be formed, to deoxidize or remove it, which is best done by a solution of ferrous sulphate, (sulphate of the protoxide of iron, ) and washing in water. From what we have said, this washing in water, and keeping the gas for any length of time over water, must be attended with great loss, as much of the gas is thereby absorbed. This may be, to a great extent, avoided by employing water at an elevated temperature, or a strong solution of common salt for the same purpose. When about to be inhaled as an anaesthetic, great care must be taxen that no oxygen or air become mixed with the protoxide; otherwise the peculiar effects described by Sir Humphry Davy are} observed instead of anaesthesia.
