![plastic power ; 3, from deviation of the organs in respect to their natural form ; 4, malformations characterised by ambiguity of sex—hermaphroditism, This distinction of hermaphroditism from other malformations constitutes the great defect of Meckel’s classification. Breschet has, in his classification, broken up Buffon’s first class into two, by separating duplicate formations from mal- formations per excessum. ‘The four orders of his classification are: 1, ageneses, devious formations with diminution of plastic power; 2, hypergeneses, with augmentation of plastic power ; 3, diplogeneses, devious formations with the fusion of germs— duplicate formations; 4, heterogeneses, with alien character of the product of generation. The further division is as follows : The first order, ageneses, breaks up into four species. (a.) Agenesie, absence—defective development. It is either partial, as in hemicephalie, aprosopie, acephalie, apleurie; or it is general, as in microsomatie (dwarfish- ness, cretinism). (6.) Diastematie, cleft formation at the median line. It is subdivided according as it affects the head or the trunk, into diastemencephalie, &c., and diastematos- ternie, &c., (c.) Atresie. (d.) Symphysie, coalition, fusion. The second order, hypergenese, presents two species, ac- cording as individual parts or the entire body are concerned. To the former species belong macrocephalie, macroprosopie, &c.; the latter consists of macrosomatie (giant growth) . The third order, diplogenese, is divisible into external, through fusion or adhesion, as in diplocephalie, diplothoracie ; and in- ternal,.through penetration (per penetrationem), The fourth order has three species. (a.) Deviation as to site, either of the entire organism [extra- uterine pregnancy | or of individual organs [ectopie]. (6.) Deviation as tonumber, polypedie—the coexistence in the uterus of several foetuses. (c.) Deviation as to colour—leucopathie, cyanopathie, cirrho- pathie.](https://iiif.wellcomecollection.org/image/b33099078_0001_0034.jp2/full/800%2C/0/default.jpg)
