 perfectly fresh and soft ; supposing these places to be above 

 the mouth of one of these immense and subterraneous riv-

 surface and spread to a great distance, until tide, wind, 

 wave and current have mixed it with the salt water of the sea.

1. Meteorological Report for the year 1827. 



From the Register of the Connecticut Academy of Arts and 

 Sciences, kept at New Haven — by Denison Olmsted, 

 Professor of Mathematics and Natural Philosophy in Yale 

 College, and Secretary of the Academy. 



[Printed by permission of the Academy.] 



In the following paper, it is proposed to lay before the 

 Academy, the results of the meteorological register for the 

 year 1827, kept by their order, with the hope and expecta- 

 tion, that similar reports will be continued from year to year, 

 forming a series from which, taken in connexion with the 

 meteorological observations already in the possession of the 

 Academy, ample materials will be furnished for ascertaining 

 the true character of our climate, by comparing it with the 

 climates of other countries.
