 ... In Var. under Dom., Ed. ii. vol. I. p. 295, such eggs are said to be laid early in each season by the black Labrador duck. In the next sentence in the text the author does not distinguish the characters of the vegetable capsule from those of the ovum. ...

... canal gradually increases until it reaches its ovarian extremity. The mucous lining of the tube is clothed by a single layer of hair-like epithelium, whose current sweeps from the ovarian toward the uterine end of the tube; and it is these movements which propel the ovum from the ...

... abortion of a decidua. Burdach (according to Beard) was the first who described menstruation as an abortive parturition. "The hypothesis," Marshall and Jolly conclude, "that the entire pro-oestrous process is of the nature of a preparation for the lodgment of the ovum is in accordance with the facts."[96] Fortunately, since we are here primarily concerned with its psychological aspects, the precise biological cause and physiological nature of menstruation do not greatly ...

... understand that the word "twins" is a vague expression, which covers two very dissimilar events—the one corresponding to the progeny of animals that usually bear more than one at a birth, each of the progeny being derived from a separate ovum, while the other event is due to the development of two germinal spots in the same ovum. In the latter case they are enveloped in the same membrane, and all such twins are found invariably to be of the same sex. The ...

... to have proved that man's soul is "a volatile odoriferous principle, capable of solution in glycerine". Psychogen is the name he gives to it, and his experiments show that it is present not merely in the body as a whole, but in every individual cell, in the ovum, and even in the ultimate elements of protoplasm. I need hardly say to so intelligent an audience as this, that these highly interesting experiments of Dr. Jaeger are corroborated by many facts, both physiological and psychological, that have ...

Its subsequent progress from the smolt to the adult condition, through the transitionary state of grilse, has been more recently traced, with ...

... affected by disadvantageous dints impressed on the body of the parent—little likely unless the dints have peculiarly penetrating consequences, as in the case of poisons. (4) A further advantage is implied in the formation of two kinds of germ-cells—the ovum or egg-cell, with a considerable amount of building material and often with a legacy of nutritive yolk; the spermatozoon or sperm-cell, adapted to move in fluids and to find the ovum from a distance, ...

After a six years' incumbency as Professor of Physiology in the University of Edinburgh, he was, in 1848, presented by the Crown to the Chair of Anatomy in Glasgow University, at that time vacant in consequence ...

... extreme case of variation in the Darwinian sense, greater in degree than, but perfectly similar in kind to, that which occurred when the well-known Ancon Ram was developed from an ordinary Ewe's ovum. Indeed we have always thought that Mr. Darwin has unnecessarily hampered himself by adhering so strictly to his favourite "Natura non facit saltum." We greatly suspect that she does make considerable jumps in the way of variation now and then, and that these saltations give rise to some ...

... of spontaneous generation were Spallanzani's experiments and observations on the physiological processes of generation among higher animals. He experimented with frogs, tortoises, and dogs; and settled beyond question the function of the ovum and spermatozoon. Unfortunately he misinterpreted the part played by the spermatozoa in believing that their surrounding fluid was equally active in the fertilizing process, and it was not until some forty years later (1824) ...

... an acquired characteristic. But the case is not in point since congenital siphilis [tr. note: sic] is, properly, due to a prenatal infection, the bacillus entering the very germ-plasm of the human ovum (egg). Medical science, generally, has become very cautious in the use of the word "hereditary." There is almost unanimity among medical men in the denial of heredity as a factor in tuberculosis and cancer. Most physicians are honest enough to say that they know considerably less about ...

... his uterine life, by {91} alcohol reaching his brain from a drunken mother. Such traits are congenital, but acquired. Native traits date back to the original constitution of the child, which was fully determined at the time when his individual life began, nine months before birth. The "fertilized ovum", formed by the combination of two cells, one from each of the parents, though microscopic in size and a simple sphere in shape, somehow contains the determiners for all the native or inherited traits of ...

... segment contains the generative organs of both sexes. The parasite (worm) becomes fully grown in three to three and one-half months. Segments then continually break off and are discharged at stool. Each ovum (egg) contains a single embryo, armed with six hooklets and contained in a thick shell. When swallowed by a pig or man these shells are digested and the embryos migrate (travel) to various parts of the body, where they change to Cysticerci or "Measles." Each contains ...

This ontogenetic fact is supremely important, for the most far-reaching conclusions may be drawn from it. In the first place, we have a clear perception that man, like all the other complex animals, inherits ...
