." It is, says Prof.
Huxley,* "quite in the later stages of development that the young
human being presents marked differences from the young ape, while
the latter departs as much from the dog in its developments, as the
man does. Startling as this last assertion may appear to be, it is
demonstrably true."
* Man's Place in Nature, 1863, p. 67.
As some of my readers may never have seen a drawing of an embryo,
I have given one of man and another of a dog, at about the same
early stage of development, carefully copied from two works of
undoubted accuracy.*
* The human embryo (see upper fig.) is from Ecker, Icones Phys.,
1851-1859, tab. xxx., fig. 2. The drawing of this embryo is much
magnified. The embryo of the dog is from Bischoff,
Entwicklungsgeschichte des Hunde-Eies, 1845, tab. xi., fig. 42 B. This
drawing is magnified, the embryo being twenty-five days old. The
internal viscera have been omitted, and the uterine appendages in both
drawings removed. I was directed to these figures by Prof. Huxley,
from whose work, Man's Place in Nature, the idea of giving them was
taken. Haeckel has also given analogous drawings in his
Schopfungsgeschichte.
After the foregoing statements made by such high authorities, it
would be superfluous on my part to give a number of borrowed
details, shewing that the embryo of man closely resembles that of
other mammals. It may, however, be added, that the human embryo
likewise resembles certain low forms when adult in various points of
structure
