Seite 122 - ... have occasionally seen a thin slit of bone divide this hollow, making two. At their base is found a small sac, containing two or three drops of venom, which resembles thin honey. The sac is so connected with the cavity of the fang during its erection that a slight upward pressure forces the venom into the fang at its base, and it makes its exit at a small slit or opening near the point with considerable force ; thus it is carried to the bottom of any wound made by the fang. Unless the fangs are...
Seite 455 - ... must therefore be confined to dead matter ; but such apprehensions are, it is believed, groundless, or, at all events, premature. All parts of living structures are allowed to be in a state of incessant change, of decomposition and renewal. The decomposition occurring in a living membrane, while effecting osmotic propulsion, may possibly, therefore, be of a reparable kind In other respects chemical osmose appears to be an agency particularly adapted to take part in the animal economy.
Seite 449 - This name was applied to the power by which liquids are impelled through moist membrane and other porous septa in experiments of endosmose and exosmose. It was shown that with a solution of salt on one side of the porous septum and pure water on the other side (the condition of the osmometer of Dutrochet when filled with a saline solution and immersed in water), the passage of the salt outward is entirely by diffusion, and that a thin membrane does not sensibly impede that molecular process. The...
Seite 98 - Imagine the case of a simple thermal siliceous spring, whose waters trickle down a gentle incline ; the water thus exposed evaporates speedily, and silica is deposited. This deposit gradually elevates the side over which the water passes until finally the latter has to take another course. The same takes place here, the ground is elevated as before and the spring has to move forward. Thus it is compelled to travel round and round, discharging its silica and deepening the shaft in which it dwells,...
Seite 121 - There is much in the history and habits of the reptile 'tribes, however repulsive they may be in appearance, that is very interesting. During a sojourn of two or three months in the interior of Arkansas, which appears to me to be the paradise of reptiles, I paid some attention to that branch of natural history called ophiology. I found four distinct varieties of rattlesnakes, (erotalus,) of which the Crotalus Horridus and Crotalus Kirtlandii are by far the most numerous.
Seite 323 - Polygala veronicea, the only described Australian species of a large genus, and in close relation to one lately discovered in the Chinese empire, not only agrees, like some kinds of Comesperma, with the Austrian Polygala amara, in those qualities for which that plant has been administered in consumption, but also participates in the medicinal virtue of Polygala Senega, from North America. Gratiola latifolia and Gratiola pubescens, Convulvulus erubescens, and the various kinds of Mentha, are not inferior...
Seite 123 - But after mixing the venom with aqua ammonia, or spirits of turpentine, or oil of peppermint, or of cinnamon, or of cloves, or with nitric or sulphuric acid, it still seemed to act with undiminished energy. It is best preserved, however, for future use, by trituration with refined sugar or sugar of milk. A very fine large cotton-mouth snake, being captured by putting a shoestring around him, became excessively ferocious, striking at even the crack of a small riding whip.
Seite 101 - Over the surface curls a light vapour, the water is of the purest azure, and tints with its own hue the fantastic incrustations on the cistern walls ; while, at the bottom, is often seen the mouth of the once mighty geyser. There are in Iceland traces of vast, but now extinct, geyser operations.
Seite 512 - These crystals are of a beautiful garnet-red color by transmitted light, and have a beautiful iridescent green by reflected light. To this body the name murexide was given, from the murex, or shell-fish, from which it was supposed the Tyrian purple was formerly procured. Previous, however, to the experiments of Liebig and Wohler, Dr. Prout had described the same substance under the name of purpurate of ammonia, but obtained in a somewhat different way. So readily is this body formed, that a solution...
Seite 465 - ... five months without being taken down, and that the zincs last such an unprecedented time. The relative cost of working these three batteries, without taking local action into consideration, supposing each equally free from local waste, is as follows; and the estimate is made up from actual experiment, by computing the destruction of battery material in each, necessary to accomplish a given equal amount of work — say the deposition of a pound of silver in the decomposition trough. To accomplish...
