Here in Dr. Bell's laboratory, or in the fields on the shore of the great Bras d'Or, I have spent many delightful hours listening to what he had to tell me about his experiments, and helping him fly kites by means of which he expects to discover the laws that shall govern the future air-ship.

He had just constructed a boat that could be propelled by a kite with the wind in its favor, and one day he tried experiments to see if he could steer the kite against the wind.

The best-known of Joule's experiments was that in which a brass paddle consisting of eight arms rotated in a cylindrical vessel of water containing four fixed vanes, which allowed the passage of the arms of the paddle but prevented the water from rotating as a whole.

Some of these experiments were made on Salisbury Plain and others in the Bristol Channel between Lavernock and Flat Holm and Bream Down in 1897.

The values assigned to H were calculated from H= 2ni/r, and ranged from 3.9 to 585, but inasmuch as no account was taken of any 2 Since in most practicable experiments H 2 is negligible in comparison with B 2, the force may be taken as B 2 /87r without sensible= error.

On the other hand, the vast number of experiments in the cropping of the tails and ears of domestic animals, as well as of similar operations on man, are attended with negative results.

The results of these experiments will be found in a compendium issued from the Rothamsted Agricultural Experimental Station.

Laura Bridgman was born at Hanover, New Hampshire, December 21, 1829; so she was almost eight years old when Dr. Howe began his experiments with her.

The human race is interested in these experiments, though a few old women who are incapacitated for them, or who own their thirds in mills, may be alarmed.

The third room is filled with my wizard mad scientist husband's electronic hub bub of messy experiments.

She shook her head, not sharing his excitement about his experiments.

It was not until the middle of the 18th century that experiments due to Benjamin Franklin showed that the electric phenomena of the atmosphere are not fundamentally different from those produced in the laboratory.

Ramsay, repeating these experiments, found that the inert gas emitted refused xIIl.

S., is famous in connexion with the socialist experiments of Robert Owen.

The results of these first experiments were not encouraging, owing mainly to the poor class of animals, but the exporters persevered, and the business steadily grew in value and importance, until in 1898 the number of live cattle shipped was 359,296, which then decreased to 119,189 in 1901, because of the foot-and-mouth disease.

The department of agriculture has an experiment station, established by the state in 1896, in which important experiments in cotton breeding have been carried on.

P. Joule to achieve; his experiments conclusively prove that heat and energy are of the same nature, and that all other forms of energy can be transformed into an equivalent amount of heat.

He also determined a roughly approximate value for the mechanical equivalent of heat from the results of these experiments.

In such experiments the molecular energy of a gas is converted into work only in virtue of the molecules being separated into classes in which their velocities are different, and these classes then allowed to act upon one another through the intervention of a suitable heat-engine.

Hughes made some remarkable observations and experiments in or between the years 1879 and 1886 though he did not describe them till some twenty years afterwards.

Marconi's earliest experiments with this apparatus were made in Italy.

This transmitting plant was completed in December 1901, and Marconi then crossed the Atlantic to Newfoundland and began to make experiments to ascertain if he could detect the waves emitted by it.

In the same year numerous experiments were tried with the assistance of an Italian battleship, the " Carlo Alberto," lent by the Italian government, and messages were transmitted from Poldhu to Kronstadt, to Spezia, and also to Sydney in Nova Scotia.

Experiments bearing on this subject were subsequently made by a great number of investigators.4 Page's discovery is of considerable importance in connexion with the theory of action of various forms of telephone, and was a very important feature in the early attempts by Reis to transit music and speech.

The suggestion of Bourseul and the experiments of Reis are founded on the idea that a succession of currents, corresponding in number to the successive undulations of the pressure on the membrane of the transmitting instrument, could reproduce at the receiving station sounds of the same character as those produced at the sending station.

The experiments with this form were not successful, and, with the view of making the moving parts as light as possible, he substituted for the comparatively heavy lever armature a small piece of clock spring, about the size of a sixpence, glued to the centre of the diaphragm.

This answered sufficiently well to prove the feasibility of the plan, and subsequent experiments were directed to the discovery of the best form and arrangement of the parts.

A cylinder of chalk was used in some of Edison's later experiments with this receiver.

Experiments very similar to these of Edison were made by Elisha Gray of Boston, Mass., and described by him in papers communicated to the American Electrical Society in 1875 and 1878.

In these experiments the electric current passed through the fingers of the operator's hand, which thus took the place of the spring in Edison's apparatus.

Hughes, while engaged in experiments upon a Bell telephone in an electric circuit, discovered that a peculiar noise was produced whenever two hard electrodes, such as two wires, were - drawn across each other, or were made to touch each other with a variable degree of firmness.

Gaine, general manager of the company, stated before the Select Committee that in the view of the directors the bargain was a hard one, because it gave no consideration in respect of the goodwill of the great business, with its gross income of over £ 2,000,000 per annum and its net revenue of over £750,000, which the company had built up. The company had had to pay for all the experiments and mistakes which are inherent in the launching and development of any new industry.

There are now four circuits between London and Paris, one between London and Lille, and two between Londofi and Brussels, the last carrying an increasing amount of traffic. Experiments have been made in telephonic communication between London and Rome by way of Paris.

Experiments hitherto made show that the cultivation of Oriental tobacco may.

Before proposing the reintroduction of the tax, Sella and his friend Ferrara improved and made exhaustive experiments with the meter.

Many experiments point to certain small grains of starch which are capable of displacement as the position of the cell is altered.

In 1826 the idea occurred to him of attacking this problem by means of pendulum experiments at the top and bottom of a deep mine.

The experiments eventually took place at the Harton pit near South Shields in 1854.

They thought that it was not sufficient to trust to the ear alone, to determine the principles of music, as did practical musicians like Aristoxenus, but that along with the ear, physical experiments should be employed.

In order to explain the course of the revolution which came to a head in 1905 it is necessary to say a few words about constitutional plans and liberal experiments, initiated from above, which had preceded it.

The draw-bar pull for a given load is a function of the speed of the train, and numerous experiments have been made to find the relation connecting the pull with the speed under various conditions.

From Aspinall's experiments it appears to be about 17 lb per ton, and this value is plotted on the diagram.
