Vinegar Clyster.
This clyster is made by mixing three ounces of vinegar with five of water-gruel.
It answers all the purposes of a common clyster, with the peculiar advantage of being proper either in Inflammatory or putrid disorders, especially in the latter.
We think it unnecessary to give more examples of this class of medicines, as ingredients adapted to any particular intention may be occasionally added to one or other of the above forms.
