The following- facts demand attention: Tn 1876 the in- 
clination of the lunar orbit was at its minimum, and in like 
manner the storms and tornadoes were also at minimum ; 
thereupon the inclination increased, and was followed by an 
increase in violent storms ; then a decline in the inclination 
occurred in 1878-79, which was followed by a similar decline 
in the frequency of storms and tornadoes. Thicreupon the 
inclination rose high the following year, 1880, and the tor- 
nadoes which in the preceding year numbered only 98, now 
reached the number of 269. Again there was a decline in 
the inclination, and again there was a simultaneous decrease 
in the frequency of tornadoes, and as the inclination reached 
its maximum in 1883, the storms and tornadoes also reached 
their maximum at the same time ; and as the inclination again 
fell to its lowest minimum in 1887-88. the same epoch was 
also characterized l>y a minimum for violent storms and tor- 
nadoes.
