Seite 84 - Salmon,' from which it would appear that the male and female fishes having jointly made a furrow in the gravel, place themselves one on each side of it, and throwing themselves on their sides " again come together, and rubbing against each other, both shed their spawn into the furrow at the same time. This process is not completed at once ; it requires from eight to twelve days for them to lay all their spawn.
Seite 81 - A pair of fish are seen to make a furrow, by working up the gravel with their noses, rather against the stream, as a salmon cannot work with his head down stream ; for the water, then going into his gills the wrong way, drowns him.
Seite 87 - Transactions of the Royal Society. Nearly 150 separate copies of the paper, printed partly at the private expense of Mr. Warren De La Rue, were distributed, chiefly to foreign observatories, scientific institutions, and distinguished astronomers and physicists.

Seite 108 - Tubes small, very slender, generally more or less contorted below, smooth, wrinkled or regularly annulated beneath a smooth transparent epidermis ; slightly and subunilaterally branched ; the branches going off nearly at right angles to the stem, and a little constricted at their base ; gregarious, forming a denselytangled mass of half to three-quarters of an inch in height. The polyp of this zoophyte had not been observed, for which reason Mr Alder considered that its claim to a place in the genus...
Seite 130 - Polypidom rectilinear, elongated, cylindrical, composed of aggregated tubes, generally without branches, which, when they occur, are of the same character as that from which they spring. Cells arranged on all sides, in more or less regular and equidistant longitudinal rows, giving a section of the stem a star-like appearance.
Seite 81 - ... stream, as a Salmon cannot work with his head down stream, for the water then going into his gills the wrong way, drowns him. When the furrow is made, the male and female retire to a little distance, one to the one side and the other to the other side of the furrow : they then throw themselves on their sides, again come together, and rubbing against each other, both shed their spawn into the furrow at the same time.
Seite 83 - upon the 14th of October last, placed in a running stream, and on examining the box [in April], several of the ova were found to be hatched." On this latter experiment, Mr. Hogg observed, that the result could only be accounted for by one of the two following methods. Either the ova of the female trout had in some way received the influence of the fecundating principle of the male trout, previous to Dr. Robertson's depositing them in his perforated zinc box ; or, the perforated zinc box, which contained...
Seite 105 - Fusut aittigtuu from deep water. Cullercoats. 2. E. eapillare, n. sp. Alder (p. 15, PI. I, figs. 9, 12). Polypary minute, very slender, thread-like, a little branched, transparent, pale horn-coloured, smooth, excepting two or three faint rings near the origin of each branch. Polypes terminal on the upper branches, vase- or pear-shaped, with a single row of eighteen or twenty, long, slender tentacles ; reproductive capsules on separate snort branches near the lower part of the stem, or clustered on...
Seite 127 - II, fig. 9). Stem creeping, plain ; pedicles long, nearly smooth, with two or three slight spiral twists at the base and two or three spherical rings at the top, one of which is within . the cup : cells rather long, with parallel sides, wrinkled or lineated longitudinally ; marginal denticles 10, of a squared or castellated form, a little indented at the top. Height, about 5 inch. Camp, volubilis, var., Hincks, in 'Ann. Nat. Hist.,
