This is well shown in the drawings given by Owen of the bones of the leg of the horse, ox, and rhinoceros. It is an important fact that rudimentary organs, such as teeth in the upper jaws of whales and ruminants, can often be detected in the embryo, but afterwards wholly disappear.

In 1910 Harrison, having placed fragments of an embryo frog in a drop of coagulated lymph taken from an adult, saw them continue their development for several weeks, the muscles and the epithelium differentiating, the nervous rudiments sending out into the lymph filaments similar to nerve fibers. Since 1910 with the aid of Dr.

For a little while I fancied this must be almost as delightful for him as my own unexpected escape from the Academy that afternoon had been for me. But, gradually, my embryo intelligence rejected this theory, and I became possessed of a sense of grave happenings, almost, it might be, of catastrophe.

You must persist in thus doing, until faith and love and understanding become the habit of your life. The same rules apply if you would feel your nearness to any other person, or to all persons. Every man is in embryo a good and thoughtful and loving husband. A wise wife will give him the loving, full-of-faith, appreciative atmosphere which encourages development.

In reality the ribs are merely large and independent lower vertebral arches, which have lost their original connection with the vertebral bodies. It will be remembered that in the human embryo and that of the other vertebrates we find at first, instead of the segmented column, only a simple unarticulated cartilaginous rod.

Half of them remain in embryo, like buds of flowers that never come to bloom, . . yet they are THERE, burning in the brain and seeming too vast of conception to syllable themselves into the common speech of mortals!

But there is no obvious reason why, for instance, the wing of a bat, or the fin of a porpoise, should not have been sketched out with all the parts in proper proportion, as soon as any structure became visible in the embryo.

If we have identity between the embryo and the octogenarian, we must have it also between the octogenarian and the corpse, and do away with death except as a rather striking change of thought and habit, greater indeed in degree than, but still, in kind, substantially the same as any of the changes which we have experienced from moment to moment throughout that fragment of existence which we commonly call our life; so that in sober seriousness there is no such thing as absolute death, just as there is no such thing as absolute life.

I know the cut of him; if he had any spite he would take it out on a gentleman. He thinks we are made of different clay from him." And the embryo republican threw back his shoulders impatiently. "So we are," returned the other, with the Englishman's ingrained belief in caste; "but, to be sure, you feel it with some more than with others, with the young man more than with his father.

In the largest mammals, the embryo needs a much longer period for its development in the womb a year and a half in the rhinoceros, and ninety weeks in the elephant. In these cases pregnancy lasts twice as long as in the case of man, or one and three-quarter years. In the smaller mammals the embryonic period is much shorter.
