If we add to the table of earthquakes in Eastern America, 
given in vol. v of the Naturalist, the more recent earthquakes 
observed in Canada, the proportion for the several months will 
stand as follows :— 
Ma u 
8; November, 15; December, 8. Total, 78. 
Thus of seventy-eight recorded Canadian and New England 
earthquakes, fifteen, or nearly one-fifth, occurred in November; 
forty, or more than half of the total number, in the third of the 
rel extending from October to January inclusive. The pub- 
ished catalogues show that similar ratios have been observed 
elsewhere, at least in the Northern hemisphere. 
nh some earthquakes a low state of the barometer has been 
observed, as if a diminution of atmospheric pressure was con- 
rust causing vibration. In the present case no very decided 
suc 
high for the season, and this rapid fluctuation was accompanied 
with much atmospheric disturbance in the region of the lakes and 
the St. Lawrence Valley. e weather map issued by the War 
Dep 
shows a low barometer in the Gulf of St. Lawrence and a high 
barometer in the Middle States—the area of the earthquake being 
about half way between the extremes. 
n sre nit f with previous earthquakes it has been observed 
that the greatest intensity of the shocks appeared near the june- 
tion of the Laurentian with the Silurian formations. This would
