(Fig. 15.) — It is placed at theanterior edge of the inner side of the orbit. What is the form of this bone ? — Its external side*consists of a flat posterior surface and an anterior groove;its internal surface is exactly the reverse. What is situated in its groove ?^—The lachrymal rests upon its flat surface ? — The ball of theeye rests in part on it. What cavities do its inner surfaces cover? — Thesethmoidal cells. What are its connexions ? — It is joined to the os frontis, os aelh-moides, and os maxillare, by the lachrymal sutures. ^ ^ ^ What is its foetal state ? — It considerably resembles that of theadult. What is its use?—It forms part of the groove for the lachrymalsac and duct, and also the anterior part of the inner side of the OSSA MALARUM. They Fig. 16. What are the situations of the ossa malarum ? (Fig. 16.)-form the prominence of the cheeks. What is the general form of thesebones ?-They are irregular in shape. What are the elevations and de-pressions of these bones ? — Themaxillary processes, the inferiororbitar processes; the internal or-bitar processes; the external orbi-tar processes, and the zygomaticprocesses. ^^ The orbital depres-sions^ and the temporal depressions. What are lodged in the depres-sions ? — The orbitar depressioncontains part of the ball of the eye,and the temporal depression part ofthe temporal muscle. What are the foramina ? — Theyhave but one foramen, placed below the middle of their upper does this foramen transmit ? — A nervous
