during activity provoked by pilocarpine. Observations on identical material show that the behaviour of the neutral red-Sudan III stained material is similar to that of the osmiophile Golgi lipoid, thus establishing the identity of the two stained substances. Further Sudan III is only soluble in neutral red solution and not in water, while neutral red is lipoid soluble, and in a mixture of lipoid and water, the lipoid takes up most of the red. Since the Golgi material is the largest mass of lipoid in the cell, the presence of neutral red in the Golgi lipoid is

accounted for. Further evidence of the fate of some of the Golgi lipoid by discharge into the gland lumen is given,
