Although, as stated above, the ossicle appears to be merely a detached fragment of the lachrymal, there seems good reason for regarding it as the representative of the accessory ossicle which has for long been known to occur, with sufficiently remarkable frequency, in the human skull, and which was apparently first detected by Rosen-. Fig. 1. I laclirymal; Skull of Lion. Lateral asiject. accessory ossicle. / frontal; vi malar; sm maxilla; MÜLLER (1), who remarked its presence in two skulls. In 1858, it was called the "Nebenthränenbein" by Luschka (2), who concluded that it was merely an intercalated ossicle standing in no very precise relation- ship. A little later (1859), Budge (3) found it to occur in as many as 6 skulls out of 184; and in 1860 its characters were examined by Mayer (4) who regarded it as a small half-separated Pars facialis of the lachrymal bone itself. Macalister (5), in his paper on -the variations and morphology of the human lachrymal bone, refers to Luschka's "Nebenthränenbein" under the name of Ossiculum maxillo-frontale, and claims to have found it in 17o of the skulls examined by him. He considers it to be "formed by a detached slip of the maxilla along the upper part.
