The activity of succinic dehydrogenase in the submaxillary gland of the rat was shown to vary with the age of the animal. The activity per g. of glandular tissue increased from the age of 3 weeks up to 3 months and thereafter remained constant to the age of 6 months. The weight of the submaxillary gland was significantly decreased after hypophysectomy and the activity of succinic dehydrogenase per g. of submaxillary glandular tissue was significantly lowered, but there was no change in the activity of cytochrome oxidase or of fumarase.
