1 Formula : Crush 75 to 10U grams of gelatin or clear glue, preferably the former, and put in a 

 bottle with 100 cubic centimeters of commercial acetic acid (no. 8) and set in a warm place for 

 three or more days, shaking occasionally. Then add 100 cc of water, 100 cc of 95$ alcohol and 15 to 

 20 cc of glycerin. Operations may be hastened by heating the glue and acid in a water bath, but 

 great care must be exercised if this is done.
