114 TRANSACTIONS OF THE ILLINOIS 



Before closing, I will give a few essential points determining the 

 causes and disclosing the laws of the movements of storm centers. We 

 have already stated that a low barometer attracts a low barometer, and 

 that the wandering, temporar)' low barometers are attracted to and ab- 

 sorbed by the fixed, permanent low barometers. For the North American 

 continent, the controlling barometer is the fixed low barometer around 

 Iceland and southeast Greenland. All the temporary and wandering low 

 barometers on the American continent, that are free, will therefore pass to 

 it in a straight line. 



For instance, see the movements of the tropical storms that burst 

 from the south on the Gulf States. They follow the coast of the Atlantic 

 in a direct line to Iceland. The continental storm centers generally ori- 

 ginate in Manitoba, consequently they would proceed in a straight line 

 to the southern point of Greenland, were it not for the high barometer 

 over Hudson's Bay, which repels them southeast into the upper valley of 

 the Missouri, whence they sweep around the Hudson's Bay region with a 

 graceful curve, over or along the southern shores of the great lakes, down 

 the valley of the St. Lawrence towards Iceland. Low barometers are 

 flanked by two high barometers, between which they are driven as a 

 wedge, move slowly, and develop intense cyclonal energy. For examples, 

 see the disastrous cyclone of Nova Scotia, in August, and that of Florida, 

 in October, already mentioned. 



Here opens a wide field for investigation and discussion, upon which 

 we cannot enter for the present. 



The Society adjourned until nine o'clock tO-morrow morning. 



THIRD DAY. 



MORNING SESSION. 



The Society met at nine o'clock — President M. L. Dunlap in the 

 chair. 



The meeting was opened with prayer by Suel Foster, of Iowa. 



ELECTION OF OFFICERS FOR THE ENSUING YEAR. 



Mr. Scofield moved that the rules be suspended, and that a commit- 

 tee of five be appointed on nominations. 



This was objected to by Messrs. Minkler, Flagg and Nelson, and con- 

 sequently the election was proceeded with in the usual manner, viz., by
