Abstract

In the first part of the present series of communications I have given a general discussion of the apparatus and methods of observation employed in the investigation of the seiches of Loch Earn, and have also mentioned some of the errors to which seiche observations are liable, and how they may be avoided or corrected. It may be useful to enumerate here certain of these errors, omitting for the most part those that arise from the construction of the instruments, and can be eliminated by proper design and by preliminary tests.
