    A.—Congenital Smallness of both hcihies. Vrolik* mentions this as occurring in animals, and in tlie human subject it is said to have been noticed in new-born childi-en by Moschner, Schubarth, and others.f The works of these latter authors are inaccessible to me, but I have col- lected the following series of cases illustrative of the above deformity, from the works which I have been able to obtain. 1. Ottot gives a drawing and description of a seven months' foetus, the subject of hydrencephalocele, concern- ing whose maxillae he remarks,§ os apertum et eo valde deturpatum est, quod margo superioris maxillse sex lineas prse margine inferioris maxillae et mento prominet, ita ut labium superius inf eriori non sit impositum sed propositum. From the di-awing it seems probable that the inferior maxilla was here of unusually small size. 2. The same author,]] in describing an infant that lived thi-ee hours, and possessed supernumerary fingers and toes, remarks Maxilla inferior paullo brevior est, caeterum nor- rnaHs, and 3. In describing If a monstrous new-born infant with incui-ved upper extremities, says, labium superius et maxillae superioris margo dentalis- bene se habent; palatum bene fomicatum atque latum est. Mandibula atitem tam brevis et parva est, ut mentum ceteroquin satis rotundatum, limbus alveolaris inferior et lingua nimis retro posita sunt. Itaque maxilla superior prae inferiore dimidium pollicem prominet. * * * nervi hypoglossi, glossopharyngei et rami linguales quinti paris non sunt imminuti, quamvis parva sit lingua. Mandibula brevissima, sed dm-a et crassa et in synneurosi sua nimis ossificata est; protuberantia ejus mentalis simul est eximia et in acutum quasi marginem desinet. This description leaves no room to doubt that Otto is describing an abnormally small lower jaw, though cases 1 and 2 are so incomplete as to be open to some doubt. 4.
