This may be a critical difference for a generation reared on instant messaging and T1 connection speeds.
The temperature at the base of this layer due to the heat being continually evolved in it, is, say, T1°.
All the "odd" sheets are connected with T, all the "even" with T1.
Let v1 denote the velocity of T1 at any given instant; v2 that of T2.
Let T1 be the time of vibration when the masses are in one of the usual attracting positions.
