This short monograph includes approximately 70 pages of discussion, illustrated by a few tables, figures and graphs and by one photograph of a roentgenogram. The subject is introduced by a brief description of the embryologic, the histologic and the anatomic characteristics of the pineal gland. The author then considers calcification of the gland, methods of determining the position of the gland from roentgenograms, forms the calcification may assume and structures which may be confused with the pineal body. The incidence of calcification in the various decades of life is determined in 1,200 cases.

Quotations from the literature are incomplete, and results are stated without evaluation of the research involved. Many opinions expressed are unsupported by scientific data.
