Side 109 - And it is to be hoped the day is not far distant when the farmers who allow thistles, ragweed, and the like, to seed on their fields, without having attempted to prevent them, will be subjected to a penalty •f.
Side 294 - ... dispensed with by those who study both the static and the dynamic relations of electricity ; every current where there is resistance, has the static element and induction involved in it, whilst every case of insulation has more or less of the dynamic element and conduction ; and we have seen that with the same voltaic source, the same current in the same length of the same wire, gives a different result as the intensity is made to vary, with variations of the induction around the wire.
Side 440 - More Worlds than One. The Creed of the Philosopher and the Hope of the Christian.
Side 291 - This line of deep-sea soundings seems to be decisive of the question as to the practicability of a submarine telegraph between the two continents, in so far as the bottom of the deep sea is concerned.
Side 291 - Ireland, the distance between the nearest points is about 1,600 miles ;* and the bottom of the sea between the two places is a plateau, which seems to have been placed there especially for the purpose of holding the wires of a submarine telegraph, and of keeping them out of harm's way. It is neither too deep nor too shallow ; yet it is so deep that the wires, but once landed, will remain forever beyond the reach of vessels...
Side 294 - If the induction remain undiminished, then perfect insulation is the consequence; and the higher the polarized condition which the particles can acquire or maintain, the higher is the intensity which may be given to the acting forces. If, on the contrary, the contiguous particles, upon acquiring the polarized state, have the power to communicate their forces, then conduction occurs, and the tension is lowered, conduction being a distinct act of discharge between neighbouring particles.
Side 294 - These terms, or equivalents for them, cannot be dispensed with by those who study both the static and the dynamic relations of electricity ; every current where there is resistance has the static element and induction involved in it, whilst every case of insulation has more or less of the dynamic element and conduction ; and we have seen that...
Side 294 - This is in perfect accordance with the principles and with the definite character of the electric |force, whether in the static, or current, or transition state. When a voltaic current of a certain intensity is sent into a long water wire, connected at the further extremity with the earth, part of the force is in the first instance occupied in raising a lateral induction round the wire, ultimately equal in intensity at the near end to the intensity of the battery stream, and decreasing gradually...
Side 6 - I wish to produce the true effect of the printing wood, I alter the process as follows : — I wet the surface upon which the impression is to be taken •with dilute acid, and then I print with the veneering wood previously wetted with diluted liquid ammonia ; it is evident that in this case the alkali neutralizing the acid, the effect resulting from the subsequent action of heat will be a true representation of the printing surface. Such is thermography, or the art of printing by means of heat....
