Page 36 - ... for a term of one year, two for a term of two years, and two for a term of three years.
Page 114 - Kyan thought the evil might be stopped; that the commencement even might be prevented by the application of corrosive sublimate, in consequence of the chemical combination which takes place between the corrosive sublimate and those albuminous particles which Berzelius, and others of the highest authority, consider to exist in and form the essence of wood : which being the first parts that run to decay, cause others to decay with them.
Page 53 - The earth round the place, for above two miles, has this surprising property, that by taking up two or three inches of the surface, and applying a live coal, the part which is so uncovered immediately takes fire, almost before the coal touches the earth ; the flame makes the soil hot, but does not consume it, nor affect what is near it with any degree of heat.
Page 53 - When the weather is thick and hazy, the springs boil up the higher, and the naphtha often takes fire on the surface of the earth, and runs in a flame into the sea in great quantities, to a distance almost incredible.
Page 53 - ... close the mouth of the spring : sometimes it is quite closed, and forms hillocks that look as black as pitch, but the spring, which is resisted in one place, breaks out in another. Some of the springs, which have not been long open, form a mouth of eight or ten feet diameter.
Page 111 - ... immersion; but this practice was soon abandoned and injection by pressure substituted. In 1838 Sir William Burnett, formerly Director General of the Medical Department of the English Navy, made known to the public his new process for treating wood. The invention consists of destroyng the tendencies of certain vegetable and animal substances to decay by submitting them to the action of chloride of zinc. The degree of dilution recommended by Mr. Burnett is one part volume by fifty parts of water....
Page 112 - ... railroads have adopted the chloride of zinc process." Steaming the wood under a pressure of sixty to seventy pounds per square inch, as done in Germany, preparatory to burnettizing, no doubt adds to its durability. Tredgold considers that steamed timber shrinks less and stands better than that which is naturally seasoned.
Page 24 - This method of transmitting power depends upon two principles in mechanics: (1) The dynamic force is measured by the product of the force and the velocity with which it moves ; (2) In mechanical work, power may be exchanged for velocity, and velocity for power. To illustrate, let us suppose a bar of iron, having a cross sectional area of one square inch, to move endlong at the rate of two feet per second. Now, if the resistance overcome is say 5,000 pounds, work will be performed at the rate of 10,000...

Page 19 - The Sawyer spindle was limited in speed. With an unbalanced load it would vibrate and gyrate, at more than 7,500 turns per minute, so as to become useless. The Rabbeth spindle, on the contrary, will bear any speed desired, and the limit of production of the frame is transferred from the speed that the spindles will bear to the speed with which operatives can make good piecings of yarn broken in the o|)eration of spinning.
