Obs. The strength of this ointment, as prescribed by different parties varies greatly, the proportions of the iodide ranging from 1⁄32 to 1⁄8 of the whole, to adapt it to particular cases. When other ingredients are added, the iodide must be used in a perfectly dry state, and in fine powder, instead of being dissolved in water. This is particularly necessary when it is to be mixed with mercurial ointment.
