Baer's law that the characters of the large groups appear earlier in embryogeny than the characters of the lesser classificatory divisions. From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
The primitive Annelid mouth, however, does not appear in the embryogeny of Vertebrates, for the great development of the brain crowds it out of existence. From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
Opinions differed considerably as to the primitive mode of origin of the two-layered sac which was very generally admitted to be of constant occurrence in early embryogeny. From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
The number of stages in embryogeny is proportionate to the complexity of the adult; the younger the embryo the simpler its organs -- such is the general formula of the relation between the embryo and the adult. From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
His study of embryogeny impressed on him the frequent occurrence of deviations from the norm in individual development “Errors” arise that produce new characteristics of organisms and are then trans - mitted to offspring. From Wordnik.com. [EVOLUTIONISM] Reference
Mr. Brown, that it was a disadvantage to be able to draw, I always fancy he had Bauer in his mind's eye; for had he been a writer and not a drawer, before 1800, in great probability we should have known nearly as much of embryogeny as we do now. From Wordnik.com. [Journals of Travels in Assam, Burma, Bhootan, Afghanistan and the Neighbouring Countries] Reference
The hypothesis explains also the way in which the orderly succession of stages in embryogeny is brought about, for we can readily understand that the embryo will not remember any stage until it has passed through the stage immediately preceding it. From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
Until recently, practically nothing was known about the morphogenetic processes concealed in this metamorphosis, about what cranial structures take part in it, and about the exact way in which the cetacean skull becomes transformed during embryogeny.

The correspondence between comparative embryogeny and comparative anatomy would remain too. From Wordnik.com. [Evolution créatrice. English] Reference
I will now pass on to consider the embryogeny of the Metazoa, beginning at its earliest stage in the fertilization of the ovum. From Wordnik.com. [Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions] Reference
Fabrizio of Acquapendente (Fabr. ab Aquapendente, 1537-1619), who worked in the field of embryogeny and studied carefully the valves in the veins, and finally Giulio Casserio (1561-1619), who published a series of anatomical charts.

Paleontology, in spite of the insufficiency of its evidence, invites us to believe it has; for, where it makes out the order of succession of species with any precision, this order is just what considerations drawn from embryogeny and comparative anatomy would lead any one to suppose, and each new paleontological discovery brings transformism a new confirmation. From Wordnik.com. [Evolution créatrice. English] Reference
Comparative anatomy was thus seen to be repeated and reproduced by embryogeny "(xii., p. 85). From Wordnik.com. [Form and Function A Contribution to the History of Animal Morphology] Reference
