The length, excluding lesser sinuosities, is about 60 m., Salisbury being 35 m.
The length of the river, excluding minor sinuosities, is about 75 m., the distance from Bradford to Bath being to m., thence to Bristol 12 m., and thence to the mouth 8 m.
The coast line, including larger bays, but excluding reefs, islets, keys and all minute sinuosities, is about 2500 m.
By repeated hammering and polishing the expert obtains such control of the wood-grain pattern that its sinuosities and eddies seem to have developed symmetry without losing anything of their fantastic grace.
Or, if the same plate be moved in contact with two tuning-forks, we shall, by comparing the number of sinuosities in the one trace with that in the other, be enabled to assign the ratio of the corresponding numbers of vibrations per second.
When the velocity of the jet is gradually increased there is a certain range of velocity for which the jet is unstable, so that any deviation from the straight rush-out tends to increase as the jet moves up. If then the jet is just on the point of instability, and is subjected as its base to alternations of motion, the sinuosities impressed on the jet become larger and larger as it flows out, and the flame is as it were folded on itself.
