Gingerinum

This oleo-resin of ginger may be treated like an essential oil, curd soap and althaea making a good mass. It is less troublesome than essential oils, but in such a combination as the following it is worse:

Fiat pilula. Mitte xxiv.

Here the gingerin liquefies the thymol. A fair pill is obtained by mixing the gingerin and extracts, separately mixing the rhubarb and thymol, adding to the extracts, and beating with a sufficiency of powdered althaea. [Note.- 'Gingerinum' is dog-Latin; zingiberis oleo-resina is the proper name of the preparation.]

Guaiacolum

This is the principal constituent of creosote, and is obtainable as liquid or crystals. It should be treated exactly like creosote.

Hydrargyri Iodidum Rubrum

Triturate each dose with half a grain of milk sugar and mass with glucose.

Hydrargyri Iodidum Viride

Mass with half its weight of manna, which gives an excellent pill that does not oxidise.

Hydrargyri Perchloridum

This should first be rubbed to a fine powder along with twice or three times its weight of sugar of milk, and the other ingredients, except the excipient,. added little by little, so that a perfect mixture may be produced. The following form is designed to exhibit the perchloride in a dissolved state:

M. Ft. pil. viij.

The perchloride being dissolved in the glycerin, perfect distribution is effected. If the perchloride is dissolved in ether and the solution triturated with liquorice powder, the salt is obtained in a very finely divided state, and the powder masses well with glycerin of tragacanth.

Hydrargyri Subchloridum

A very good mass is made with manna or glucose, according to the quantity in the pill.

Hydrargyri Tannas

Treat like calomel.

Hydrargyrum c Creta must not be vigorously worked in the pill-mortar, else mercury separates. It masses well with glycerin of tragacanth. If prescribed with powders or pill-masses which can be used in powder, hyd. c creta. should be carefully triturated with such ingredients first.
