 ... the ventral surface, a group of thicker setae with a strongly uncinate bidentate apex. There was above EACH of the lateral tufts of bristles a branchia, simple on a few of the foremost segments, and then strongly arborescent to the end of the body. The animal, a female filled with ova, evidently, from these characters, belongs to the family of the Amphinomidae; the only family the members of which, being excellent swimmers, live ...

... mighty din of rushing water, beating drums, cries of pilots and boatmen, the boat is hauled slowly and painfully over. According to Chinese myths, the landslip which produced the rapid was caused by the following circumstance. The ova of a dragon being deposited in the bowels of the earth at this particular spot, in due course became hatched out in some mysterious manner. The baby dragon grew and grew, but remained in a dormant state until quite full grown, when, as is the habit of the dragon, it ...

... horse's mouth, don't you? and it is the same with trout," replied Hardy; "that is, to some extent. The teeth get larger at the base, the jaw bone thickens with age, and the snout gets longer. I have often seen trout that have been reared from ova, and whose age was consequently known, and have closely observed their mouths. The fish in your stream grow fast from the great abundance of the food that trout thrive ...

... of Balanoglossus takes place according to two different schemes, known as direct and indirect, correlated with the occurrence in the group of two kinds of ova, large and small. Direct development, in which the adult form is achieved without striking metamorphosis by a gradual succession of stages, seems to be confined to the family Balanoglossidae. The remaining two families of Enteropneusta, Ptychoderidae and ...

... zoological evolution reveals a constantly diminishing reproductive activity and a constantly increasing expenditure of care on the offspring thus diminished in number.[141] Fish spawn their ova by the million, and it is a happy chance if they become fertilized, a highly unlikely chance that more than a very small proportion will ever attain maturity. Among the mammals, however, the female may produce but ...

On landing at the wharf at New Norfolk, a boy came forward and offered to drive me to the well-known salmon ponds, where, for a good many years, attempts have been made to rear salmon from ova brought from England, but it is doubtful whether they have met with success. Small fish have certainly been raised, but the question is whether they are salmon, and it is said none have attained a size sufficiently large to solve the enigma. The distance is only a ...

... of organic development. It fails entirely to explain generic and specific peculiarities; and leaves us equally in the dark respecting those more important distinctions by which families and orders are marked out. Why two ova, similarly exposed in the same pool, should become the one a fish, and the other a reptile, it cannot tell us. That from two different eggs placed under the same hen, should respectively come forth a duckling ...

It is testified also by other in other words, and to the like sense, that "Echis id est vipera sola ex serpentibus non ova sed animalia parit."[4] And it may well be, for I remember that I have read in Philostratus, De vita Appollonii, how he saw a viper licking her young.

The cure is gasoline. One or two applications destroy all living creatures or their ova. Arrangements had also been made so that the men could all have a hot bath once a week. A factory, usually a bleachery, was commandeered and about a hundred large tubs of hot water were provided. One after another the various ...

... sixty cocoons); three pairings only were obtained, and this species I found the most difficult to pair in captivity. Two moths emerged on the 5th of March, a male and a female, and a pairing was obtained; but the weather being then too cold, the ova were not fertile, the female moth, after laying about two hundred eggs, lived till the 22d of March, which is a very long time; this was owing to the low temperature. The moths emerged afterward from the 8th of April till the 25th of June. A pairing took place on the ...

... proximate principles, it is now acknowledged that there is no violation of the ordinary laws of chemical affinity. The origin of all vegetable and animal life, so far as it can be traced, is in germinal vesicles, or little cells containing granules. Such are the ova of all animals; and both vegetable and animal tissues are entirely formed from them. When the parent cells come to maturity, they burst and liberate the granules, which immediately develope themselves into new cells, thus repeating the life of their original. Now, it has been asserted, that ...

Nevertheless I made one interesting little discovery, and read, about the beginning of the year 1826, a short paper on the subject before the Plinian Society. This was that the so-called ova of Flustra had the power of independent movement by means of cilia, and were in fact larvae. In another short paper I showed that the little globular bodies which had been supposed to be the young state of Fucus loreus were the egg-cases ...

The body is here only a vehicle for ova. Furthermore, in volvox there has arisen such an interdependence of cells that we can no longer speak of it as a colony. The colony has become an individual by division of labor and ...

It may be due to: (a) Imperfect development of the ovary and nonmaturation of ova; (b) cystic or other tumors of the ovary; (c) fatty degeneration of the ovary in very obese, pampered mares; (d) fatty degeneration of the excretory tubes of the ovaries (Fallopian tubes); (e) catarrh of the womb, with mucopurulent discharge; (f) irritable condition of ...

A stringy mucus is sometimes expelled during the spells of coughing. This mucus contains the Strongylus micrurus, which can be detected, or their ova observed, under a low power of the microscope. The attack has a subacute character and is very exhausting. The parasites, by becoming entwined in balls, seriously impede respiration, which is always remarkably ...
