A SKETCH OF THE BIBLIOGRAPHY OF SEICHES. 
The following list of books and memoirs dealing with Seiches does not claim to be 
where I myself have felt the need of help. 
What may be called the ancient history of seiche observations is fully dealt with by 
of the information for that period. I must also acknowledge obligations to papers by 
Haprass, mentioned below, and to Messrs CaumMLEy and Maciacan WEDDERBURN, 
both connected with the Scottish Lake Survey, for many of the later references, |

These notices are interesting, because there is, as yet, little evidence connecting seiches with | 
seismic disturbances ; in fact, none at all in the case of ordinary seiches. . 
1776. Lapnace. “Sur les Ondes. Suite des Recherches sur plusieurs points du Systeme du Monde,” 
§ xxxvii., Hist. de l’Ac. Roy. d. Sc. Paris, Année 1776. ' 
The modern mathematics of wave motion may be said to date from Lapnacs#’s researches on 
the tides. In the memoir quoted he considers waves in a canal of uniform depth to be caus 
by the immersion of a given object, and arrives at the expression ,/{g tanh mh/m)} for the velocity 
of wave propagation. But, as he does not consider oscillatory waves, the connection of m with 
the wave length is not made clear. 1

1815. Poisson. ‘Sur la Théorie des Ondes,” Mém. d. l’Inst., i. (1816), etc. 
In the works of Caucny and Poisson the mathematics of wave motion has already talent 
modern form. Both have Lapnacn’s formula for velocity of propagation, but both are p 
occupied with the difficult problem of Lapiacn, and do not consider oscillatory surface way 
either progressive or stationary.
