This method is more rapid than Teichmanns method and crystals 1 Benzidine solution may be prepared as follows: Place of glacial acetic acid ina small Erlenmeyer flask, warm to 50° and add gram of benzidine. Heat the flask foreight to ten minutes in water at 50°. To the resultant solution add 19 of distilledwater. This solution may be kept for several days without deterioration. 2 Buckmaster considers the use of potassium chloride preferable.^Nippe: Dent. nied. Woch., 38, 2222, 1912.
