Collection of material for a handbook on dental histology to be published soon is going forward rapidly at the new Research Department of the Harvard Dental School. It will embody much of the work done by the department since its creation last year.

The laboratory of the department, which is at present housed in the Medical School , is equipped to accommodate six research workers in branches of histology, photomicrography, pathology, and by recent additions biochemistry and bacteriology. The workers in the laboratroy also have a hygienic animal house where the animals are fed according to strict instructions.

The forthcoming book will have illustrations made from actual specimens which have been prepared and are on file at the laboratory. Photomicrographs to the number of 168 and 72 lantern slides have been made and mounted. This is in the with the department's chief purpose, which is to compile clinical data and satistics with the necessary pathological and histological specimens so that it may give answers to problems based upon scientific research.

The Research Department pursues a policy of freely accepting problems of all organizations including any department in the University. A paper was recently prepared by the laboratory staff on a problem about certain parts of Icelandic skulls, which had been submitted by the Department of Anthropology in the Graduate School of Arts and Sciences.
