surface of shallow water.
Table 53 furnishes the propagation velocities for waves of
various` lengths at a varied depth of the liquid' layer, the computation
made in accordance with :ror uiu1a (23)
Let us analyze in more detail as to what is the field of
au . lication of formulas ' (2h) and (2).

by one percent less than 2f AG/, , then, velocity c obtained as per
formula (24) will be only by 0.5 percent greater than the propagation
velocity of the :4ve, as deterriiiried by formula (23) . Consequently,
formula (2L) is of adequate precision, if the dej.th of to li.uid is
no less that o.l~ of to length. of the wave ( L> Q4 ) ? This shows
what is meant by the concept of a very deep liquid, which concept
without the above evaluation might have been misleading . Z

percent. Therefore, velocity c, computed by the approximation formula
(25 ), will differ from the precise value of c, as determined by formula
(23), by less than 0.5 percent.
With relation to the atmosphere, we will frequently use the
Lagrange formula (25) for the ap7.roximate determination of the pro-
pagation velocity of a wave, since, due to the vast horizontal range of
the atmosphere as compared to -I,he thickness of atmos >he.ric layers, the
