Louis Russell is now firmly established in Concord, N. H., where he is acting as a salesman for Brown Brothers and Company, brokers, of Boston. He is residing at 16 Holt St., and his business address is P. O. Box 331, Concord.

Cliff and Mrs. Perry are progressing happily on their tour around the world on the "Empress of Australia." The Boston Sunday Herald for February 26 contained a rotogravure picture of the Perrys going down the iceless toboggan at Funchal, Madeira. From the expressions the camera had caught, we gather that they are supremely contented.

The Secretary is in receipt of a monograph reprinted from the American Journal of Diseases of Children for November, 1927, and entitled "Does the Irradiation of Cod Liver Oil Increase its Antirachitic Potency?" It is the joint production of five medical research workers, one of whom is our classmate, Dr. Arthur D. Holmes. His investigations were made in the research laboratory of the E. L. Patch Company of Stoneham, Mass.his collaborators worked at the Infants' and Children's Hospital of Boston and the Harvard Medical School. For the benefit of the doctors and scientists in our class we might add that "in general, the results of this study show that the irradiation for thirty minutes with ultraviolet rays from a quartz mercury vapor lamp of cod liver oil -potent in vitamins does not enhance its antirachitic potency, and that irradiation for two hours noticeably decreases its antirachitic activity."
