A puppy rending slippers, a child tearing up its picture books, a mungoose killing twenty chickens to feed on one, a freethinker demolishing ancient superstitions, what are they all but Dhobies in embryo?
In the same way, the embryo possesses from the first all perfections, such as the spirit, the mind, the sight, the smell, the taste—in one word, all the powers—but they are not visible and become so only by degrees.
There was that vein of coking coal over beyond the "Limestone Rim"; he nearly landed that, but the investors discovered too soon that it was 150 miles from a railroad. There was an embryo coal mine back in the hills a fine proposition but open to the same objection. Also an asbestos deposit, valueless for the same reason.
Huxham reported to the Royal Society in 1748 the history of a child which was born with a tumor near the anus larger than the whole body of the child; this tumor contained rudiments of an embryo. Young speaks of a fetus which lay encysted between the laminae of the transverse mesocolon, and Highmore published a report of a fetus in a cyst communicating with the duodenum.
This is not so, for like the adult fish, the larval tadpole, and the embryo chick, an embryo of a cat or a man is at one time constructed with a series of gill-clefts and with blood-vessels and skeletal supports of fishlike nature that are everywhere associated with gills.
Hence the formation of a medullary tube out of the outer skin takes place in the naked dorsal surface of the free-swimming larva of the Amphioxus in just the same way as we have found in the embryo of man and the higher animals within the foetal membranes.
A woman who destroys the embryo which might become a burden to the community, or is likely to be an inferior member of society, this writer urges, is doing a service to the community, which ought to reward her, perhaps by granting her special privileges as regards the upbringing of her other children.
Holding a prominent position at Cambridge, he was able to establish a sort of School of the Prophets, where Evangelical ministers in embryo were trained in the system of their party. But, besides this, he helped the cause he had at heart by becoming a sort of general adviser and referee in cases of difficulty. For such an office he was admirably adapted.
The embryos, also, of distinct animals within the same class are often strikingly similar: a better proof of this cannot be given, than a circumstance mentioned by Agassiz, namely, that having forgotten to ticket the embryo of some vertebrate animal, he cannot now tell whether it be that of a mammal, bird, or reptile.
Writing of the successive changes through which each embryo is forced to pass, the late Mr. G. H. Lewes says that "none of these phases have any adaptation to the future state of the animal, but are in positive contradiction to it or are simply purposeless; whereas all show stamped on them the unmistakable characters of ancestral adaptation, and the progressions of organic evolution.
