As soon, however, as the river had fairly left the basaltic formation, fine large flats of a light sandy soil succeeded on both sides; on which Pandanus spiralis grew in great abundance, and to a larger size than we had seen before. The bed of the river became very broad, and was covered with sands, shingle, and pebbles of the rocks of its upper course.

Warrington first kept, for many months, in a vase of unchanged water, two small gold fish and a plant of Vallisneria spiralis; and two years afterwards began a similar experiment with sea-water, weeds, and anemones, which were, at last, as successful as the former ones. Mr. Gosse had, in the meanwhile, with tolerable success begun a similar method, unaware of what Mr.
The pig is liable to many most unpleasant diseases, measles and trichina spiralis being the most fatal to the eaters of meat thus affected; but the last a small animalcule of deadly effect if taken alive into the human stomach, as is done in eating raw ham or sausage becomes harmless if the same meat is long and thoroughly boiled.

They had not seen a rise even, in any direction for miles, whilst the creek presented only occasional rocks of flat water-worn sandstone, and the screw-palm 'Pandanus Spiralis' occurred in all the water-courses, a tree that from its peculiarity would scarcely have been unnoticed or undescribed.
A western savant, having investigated the parasites existing in hogs, affirms that in western pork, eight animals out of every one hundred are affected by that muscle-boring pest so dangerous to those who have eaten the infected meat, and so well known to all students as the Trichina spiralis.
Bartholomew's Hospital, London, while dissecting the muscular tissues of a human subject, found little specks of extraneous matter, which, when taken to the professor of comparative anatomy, Richard Owen, were ascertained, with the aid of the microscope, to be the cocoon of a minute and hitherto unknown insect. Owen named the insect Trichina spiralis.
The stamens of a passion-flower do not more eagerly, as it seems, coil upwards to embrace the pistil; the beautiful stamina flower of the Vallisneria spiralis does not more determinately seek its mate than these crystal pendants covet union with their fellows below.
