Seite 20 - Leclanche galvanic battery. The instrument is read by depressing a key, which causes the needle of the galvanometer to deflect ; a pointer or vernier (moving a contact roller upon a wire in a circular groove) is then pushed to the right or to the left upon a divided scale until the needle remains stationary on the zero point, when the electrical resistance of the wire is measured upon the scale. The number indicated by the vernier is then read off, and by referring to a table of equivalents, the...
Seite 156 - they had subjected the Kew thermometers to the most rigorous test possible, and they were able to announce that in one instrument the errors left, after the application of Welsh's method of calibration and graduation, were not greater than four-thousandths of a degree Centigrade, and in no case did they much exceed one-hundredth of a degree. As it is impossible to read on these thermometers less than a hundredth of a degree with certainty, Welsh's method as applied at Kew is almost perfect.

Measure with a rule the average depth of snow, and take one-twelfth as the equivalent of water.

Seite 167 - In Great Britain there are at least four persistent types — the southerly, the westerly, the northerly, and the easterly. In spite of much fluctuation, one, or other of these types will often continue for weeks together, and tend to recur at the same date every year. The value of the recognition of type groups is shown in the followmg ways : — (1).

Although Schwackhofer first constructed his instrument for the particular purpose of determining the humidity of the air at different levels in forests, and comparing it with air at similar heights in the open country, yet he considers that it may...
