Dr. Klotz gave a preliminary communication illustrated by records 
and diagrams on the above subject. He showed the relationship of 
microseisms and areas of low barometer (storms) on the Gulf and 
adjoming Atlantic by comparison of the seismograms and daily weather 
maps; the areas of low barometer producing disturbed waters to a 
greater or less degree, with consequent pounding of the waves on the 
rocky shores, microseisms resulting therefrom, the direction of the wind 
being a factor. 
An individual minute on the seismogram of November 26, 1911, 
was measured for both components, N—S, E—W, and at intervals of 
one-fifth second, that is, 300 measures, both in time and amplitude, 
and the co-ordinates plotted to show the actual movement of the 
earth particle, producing a figure that reminds one of “Sekiya’s Wires,”’ 
only in the present instance, there is no vertical element. In this 
particular case the period was 6%+-2, and the maximum acceleration 
produced in the E—W direction was only eight tenth of a milligal, 
remembering that gravity is about 981 gals., or over a million times as 
great. 
Dr. Klotz has deduced the co-efficient of absorption from tectonic 
quakes as -00032, but gives it with reserve and similarly its inverse 
application to recorded microseisms. 
In a future paper he hopes to have more data for a more complete 
treatment of the subject. 
It is intended to instal an undagraph on the Nova Scotian coast 
and, if the physical difficulties of securing the iron pipe permanently, 
from the shore under the sea, can be successfully overcome, interesting 
and valuable results are expected.
