CONNECTION BETWEEN STORMS AND 8UNSP0TS. 393 



In 1872 I carefully re-examined the Upper Coal Measures of Missouri, 

 revising the field work of nearly all ray previous sections, and con- 

 strncted an entirely new section. In this I found the observed sections 

 to foot up 1,267 feet of Upper coal measures. To this should be added 

 not over 40 feet for a break in the connection in Atchison and Holt coun- 

 ties, and we would have a little over 1,300 feet for the total thickness of 

 the Upper Coal Measures, differing not ovei; 20 feet from my former work, 

 all resulting from a careful comparison of several hundred different sec- 

 tions. 



The Middle and Lower Coal Measures differ somewhat in thickness in 

 different portions of the state. :My section of the Middle Coal Measures of 

 North Missouri made in 1872 make them 323 feet thick. Observations in 

 1871 along the line of the Pacific Kailroad in Johnson County make the 

 Middle Measures 327 feet and the Lower Measures 290 feet. 



In 1873 examinations in South -West Missouri made the Lower Measures 

 in those counties about 300 feet thick and the Middle Measures over 300 

 feet in thickness. 



METEOROLOGY. 



The Coniiection Between Storms and Sun-Spots, with Record of 

 the Celebrated Storms of 1600 Years. 



BY COL. HENRY INMAN, OF KANSAS. 



This year has been, in the LTnited States, one of severe and remarkable 

 storms. Their rapid succession and destructive results has provoked popu- 

 lar comment, and created serious alarm. This series of terrible atmospheric 

 disturbances, which in nearly every instance have been unprecedented in 

 their grandeur and destruction, invites the suggestion that there must bo 

 some special influence to account for the apparently' exceptional meteoro- 

 logical phenomena of this season. It has prompted an examination of the 

 dates of some of the most remarkable storms that have occurred in the last 

 sixteen hundred years — a partial list of which is here presented. If a com- 

 plete record were possible of all the violent storrns of historic times, an 

 investigation of all the data in reference to their cause would undoubtedly 

 develop the fact that the remarkable atmospheric disturbances of the present 

 season should not be regarded as anomalous, but have been manifested in 

 strict obedience to a law or complication of laws, that themselves recur, andT 

 with them their accompanying phenomena, in cycles whose period is a con- 

 stant number. It will be observed by a careful comparison of dates, that' 

 the most violent and destructive storms of record meet the requirements of 

 the h3'pothesis (of the principle of which, further on). It will also bo
