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.
Or, let us say, the etheric embryos of these essentials. "The three stones constitute an eternal trinity. "As for the substance of the Spot itself, that I cannot tell, just yet. But I do know that the whole truth will come out clear in the fulfilment of the Prophecy. I am convinced that it has translated Watson, and now Harry Wendel and the Nervina." "Can you control it?" asked Chick.
We also meet numerous mechanical explanations of bodily structures, comparisons between anatomical conditions encountered in related animals, experiments on living creatures, systematic incubation of hen's eggs for the study of their development, parallels drawn between the development of plants and of human and animal embryos, theories of generation, among which is that which was afterwards called 'pangenesis' discussion of the survival of the stronger over the weaker almost our survival of the fittest and a theory of inheritance of acquired characters.
Asclepiades, that male embryos, by reason of a greater natural heat, have their joints begun to be formed in the twenty-sixth day, many even sooner, and that they are completed in all their parts on the fiftieth day; the parts of the females are articulated in two months, but by the defect of heat are not consummated till the fourth; but the members of brutes are completed at various times, according to the commixture of the elements of which they consist.
And moreover, she did not weep, but practically suggested his favourable chances, which it was a sad satisfaction to him to prove baseless, and to knock utterly over. Hints of a brighter future are its nourishment. Such embryos are not tenacious of existence, and when destroyed they are succulent food for a space to the moody grief I am describing.
The rat and squirrel and rabbit, on their part, remain together until long after they take leave of the carnivora and ungulates; while the sheep and cattle and pigs have their own branch line, which they follow in company after leaving the embryos of the other orders.
There is little doubt, ye children, that ye have been robbed of your sight by that illustrious child whose wrath hath been kindled at the remembrance of the slaughter of his race. Ye children, while ye were destroying even the embryos of the Bhrigu race, this child was held by me in my thigh for a hundred years!
The female had suffered repeated convulsions that affected the formation of the embryos and we were an ugly litter of little mongrels, doomed by our physical imperfections to a shorter-than-normal life if we were allowed to live and exposed to early drowning if we could not quickly charm ourselves into a home.
The points of structure, in which the embryos of widely different animals within the same class resemble each other, often have no direct relation to their conditions of existence.
Salter has recently given the results of an examination of about five hundred eggs produced from various crosses between three species of Gallus and their hybrids; the majority of these eggs had been fertilised; and in the majority of the fertilised eggs, the embryos had either been partially developed, and had then perished, or had become nearly mature, but the young chickens had been unable to break through the shell.
