The writer constructed a formula for a preparation termed fluid ergot, in contradistinction to the official fluid extract. As this article has proved, during several years increasing use, its superiority over the ordinary fluid extract, and clinical experience sustained the views held in regard to it on theoretical grounds, the process for its preparation might be of interest. After settling, the expressed liquids are strained and evaporated separately, when both together measure one-half as much as the ergot employed. They are mixed and sufficient alcohol added to make the liquid of 25 per cent alcoholic strength, or one-third as much as the aqueous solution. As will be seen, this preparation contains 18 percent alcohol, rendering it unobjectionable for hypodermatic use.
Fluid ergot is an opalescent, amber-colored liquid, possessing a peculiar musty odor.
It remains pretty clear unless exposed for a long time to the light or atmosphere.
