    larger tluui tho.sc of tlic cliikl; tliis tallies remarkably with what has lieeii iiiferreil on other grounds as to the (lependenee of the growth of the jaws upun the existenee of tlie teeth. This man liore no particular resenihlanee to liis mother, his brother, or iiis sister—his father was unknown, the man liaving been born during the aiisenee of tiie re[iuted father, who was a soldier. Mr. Moon (') gives two striking fannly histories. The mother had normal teetli, the father (who was dead) was said to iiave had only two incisors, and those jjointed ; there were four children, of whom one (male) had normal teeth; a female, aged ten, did not strongly resemble the others, and had teetii only sligiitly aljuormal ; another, aged eleven, had all the ineisoi's and canines small, shar])ly pointed, and hooked at the jjoints, her hair was scanty and inclined to fall out, and lier eyes were defective ; anothei', aged fifteen, had her ujiper incisors, canines, and premolars mere shai'p, curved cones; her hair was scanty and fair. Another family presented a l>oy who had no toe nor finger nails at iiirth : his hair was absent for a yeai', and at the age of nine ho liad scanty light hair, no eyel)rows, and very scanty eyelashes. He had four temporary canines, two permanent upper incisors, which were recurved and pointed, and only two molars (the u])per temporary). The sister, aged eight, had conical lower incisors, and only one u|)per incisor yet erupted, which was normal. Three others had hair and teeth normal. The ninther of these children had no ujiper lateral incisors, never liad first lower molars, second bieuspids, or third molars ; the father was in all res])ects normal. The association of certain forms of maxillary dcfoi-mity with other defects, such as congenital idiocy, may ]ierlia]is be exjilained on the ]irinci])le of cori-elation of growth, but it will be more convenient t(j defer the discussion of this Transae.
