We append two Formulae for making them:

Formula I

Concentrated Essence. - Oil of neroli, petale or bigarade, two drachms, (or one drachm of each); alcohol, sixteen fluid ounces.

For a cheaper but very good essence some oil neroli 'petitgrain may be substituted; to use the latter alone would produce a very inferior essence.

Formula II

Soluble Essence. - For the carbonators' purpose this Formula will be better and be water soluble: Oil of neroli, mixed, if desired, as in other Formula, one drachm; alcohol, and distilled water, of each, eight ounces; cut the oil with pumice and sugar, as directed; dissolve and filter.
