[THe Laumonier wax model of the ear (Collections of the Museums of the Anatomy Laboratory of Saints Pères, Paris)].

Authentified by the name of Laumonier (fecit), written on the zygomatic process of the temporal bone, a model in wax of the medial, middle and lateral ears, belongs to the collection of the "Musées Delmas, Orfila et Rouvière" in Paris. This model presents large dimensions with a great anatomical rightness. The entire temporal bone is represented with the upper part of the endocranial petrous bone removed in order to demonstrate the main elements of the internal ear (cochlea and semi-circular canals) and of the middle ear (malleus and incus). Also were represented the temporal muscle and temporal vessels, the emergency of right cranial nerves, the superior orbital fissura and its elements; the internal carotid artery and the internal jugular vein, the upper part of the sterno-cleido-mastoidal muscle and of the styloïd muscles; the middle internal part of the basis of the cranium with the trunk of the trigeminal nerve, the Gasser's ganglion with its trifurcation, the sigmoïd sinus. The dimensions are greater than the real size: total highness: 22 cm; total length: 46.5 cm; maximal highness of the ear cartilage: 16.5 cm; hemicranium width: about 22 cm. Thus the magnification of size is 2 or 3 if calculated on the basis of the external ear and 3 or 4 with reference to the half width of the cranium. The sample is fixed by two screws on a single wood board measuring 46.5 cm on 29.2 cm with two supplementary boards of 2.4 cm width under the two extreme of width, with a thickness of 1 cm.
