Pagina 201 - Can you explain this omen? Phys. A rainbow can only occur when the clouds containing or depositing the rain are opposite to the sun — and in the evening the rainbow is in the east, and in the morning in the west; and as our heavy rains, in this climate, are usually brought by the westerly...
Pagina 366 - I have never been able to conceive, that the wind in violent storms moves only in circles. On the contrary, a vortical movement, approaching to that which may be seen in all lesser vortices, aerial or aqueous, appears to be an essential element of their violent and long continued action, of their increased energy towards the centre or axis, and of the accompanying rain.
Pagina 187 - Curvature. — The rod should not be bent abruptly round sharp corners. In no case should the length of the rod between two points be more than half as long again as the straight line joining them. Where a string course or other projecting stone work will admit of it, the rod may be carried straight through, instead of round the projection.
Pagina 188 - It is essential that the lower extremity of the conductor be buried in permanently damp soil; hence proximity to rain-water pipes, and to drains, is desirable. It is a very good plan to make the conductor bifurcate close below the surface of the ground, and adopt two of the following methods for securing the escape of the lightning into the earth. A strip of copper tape may be led from the bottom of the rod to the nearest gas or water main — not merely to a lead pipe...
Pagina 65 - The height of the column in the tube above the level of the mercury in the cistern is measured by means of a graduated scale placed beside it.
