A program of extension teaching in dentistry, designed for active practitioners of the profession, has just been inaugugurated by the Harvard Dental School in conjunction with the Hartford Dental School, it has been announced by Dean L. M. S. Miner of the School.

The plan is similar to what was done by the Dental School two years ago in Providence, Rhode Island, and Springfield, when groups of Dental School instructors visited these communities to give lectures and demonstrations on new developments in the various branches of dentistry. The significant feature of this program, which comprises a dozen meetings held on Tuesday evenings during January, February, and March, is that greater emphasis than ever before is being placed upon the scientific and laboratory aspects of dental practice.

The speakers from the Dental School will include Dean Miner, Dr. R. R. Davenport, Dr. A. P. Young, Dr. F. W. Morse Jr., Dr. Kurt Thomas, Dr. G. H. Wright, Dr. V. H. Kazanjian, Dr. H. A. Kent '16, Dr. F. R. Blumenthal, Dr. B. E. Hamilton, Dr. P. R. Howe, and Miss R. L. White. Among the subjects to be covered are bacteriology; histo-pathology; eye, ear, nose, and throat infections; bone diseases; neuralgia, general diseases and diet. The Dental School Committee consists of Dr. Thomas, Dr. Davenport, and Dean Miner, ex-officio.
