Seite 112 - Sugg's steatite pin-hole burner, and lighting the gas above the gauze. " The flame is a slender cone about four inches high, the upper portion giving a bright yellow light, the base being a non-luminous blue flame. At the least noise this flame roars, sinking down to the surface of the gauze, becoming at the same time almost invisible. It is very active in its responses, and being rather a noisy flame, its sympathy is apparent to the ear as well as to the eye.
Seite 513 - The meteors to which we owe the annual display of falling stars on the 10th of August are not distributed equally along the whole course of their orbit ; it is still possible to distinguish the agglomeration of meteoric particles which originally formed the cometary nucleus from the other less dense parts of the comet ; thus, in the year 1862 the denser portion of this ring of meteors through which the earth passes annually on the...
Seite 531 - Apatura and other color-changing insects ; these colors are only optical phenomena, and differ in this respect from both of the other kinds. The epidermal colors belong to the pigment deposited in the cells of the chitinized external skin or epidermis. They are mostly metallic blue, green, bronze, golden, silver, black, brown, and perhaps more rarely red. They are very easily recognized, being persistent and never obliterated or changed after death. The hypodermal colors are situated in the non-chitinized...

Seite 82 - The one coil would only have to be placed within the cavity to be measured to enable the observer to read the temperature from time to time, without disturbing the patient, with the accuracy of which the mercury or spirit of wine thermometer employed is capable. But the same method is applicable for measuring the temperatures of distant or inaccessible places, such as the interior of stores or cargoes of materials liable to spontaneous combustion ; of points elevated above the surface of the ground;...
Seite 86 - V the horizontal columns, and the resistance being read off at the point of intersection. At each point of intersection the resistance is marked in black, and the corresponding temperature in red ink. It now remains only to be shown what is the relation between...
Seite 513 - Only fragments of this ring, composed of dark meteoric particles, become visible as shootingstars when they penetrate our atmosphere by the attraction of the earth, and ignite by the compression of the air.
Seite 41 - The more frequently soluble inorganic salts were nitrates, chlorides, bromides, and iodides ; whilst oxides, fluorides, carbonates, sulphides, and sulphates were very generally insoluble. Many saline substances, especially certain chlorides, bromides, iodides, and sulphates, absorbed ammonia freely, and swelled greatly, but did not dissolve. The behavior of the chlorides of mercury was peculiar.
Seite 436 - One day he seized his strap and began to throw it at the food, retaining his hold of one end. He took pretty correct aim, and finally drew the pieces to within reach of his hand. This performance he constantly repeats, hooking and pulling the articles to him in turns and loops of the strap. Sometimes he loses his hold of the strap. If the poker is handed him, he uses that with some skill, for the recovery of the strap. When this is drawn in, he secures his food as before. Here is an ac.t of intelligence...
Seite 423 - Yet the oldest of them doubtless grew from seed which was shed long after the names of the pyramid-builders had been forgotten. So far as we can judge from the actual counting of the layers of several trees, no Sequoia now alive can sensibly antedate the Christian era. Nor was I much impressed with an attraction of man's adding.
