_Prep._ 1. (B. P.) _Extractum Ergotæ Liquidum._ Ergot in coarse powder,
16; ether, 20; distilled water, 70; rectified spirit, 8. Shake the ether
in a bottle with half its bulk of the water, and, after separation, decant
the ether. Place the ergot in a percolator, and free it from oil by
passing the washed ether through it; remove the marc and digest it in the
remainder of the water for twelve hours at 160° F. Press out the liquor,
and evaporate it to 9, and when cold add the 8 of spirit; allow it to
stand for an hour to coagulate, filter, and make up the quantity to
16.--_Dose_, 15 to 30 minims.
According to Squire, the amount of ether employed should be double the
above, in two percolations, and the marc should be dried in the air before
digesting with water. See ERGOTINE (Bonjeau's).
