Meteorological Report for the year 1828. 



Art. XI. — Meteorological Report for the year 1 828 ; by 

 Denison Olmsted, Professor of Mathematics and Natural 

 Philosophy in Yale College. 



From the papers of the Connecticut Academy of Arts and Sciences. 



At the close of the year 1827, I laid before the Academy 

 an abstract of our Meteorological Register, for that year,* in- 

 timating at the same time a hope and expectation that similar 

 reports would be made from year to year, until we should 

 obtain a series of observations sufficiently extensive, to ena- 

 ble us to ascertain the true character of our climate. In 

 accordance with such a plan, I beg leave now to present to 

 the Academy, the meteorological results obtained during 

 the year 1828, comparing them occasionally with the cor- 

 responding observations of the preceding year. 



Table I. — Shewing the mean Maximum and Minimum of the Thermome- 

 ter for every month in the year, with the corresponding states of the Ba- 

 rometer. 



Note. — For the year 1827, the observations taken at sun rise and at 2 P. M. 

 are assumed as the minima and maxima ; for 1828, a more correct maximum 

 has been obtained by varying the hour of observation in the afternoon from 2 

 to 3 o'clock, at different seasons of the year. 



Remarks. — I. The Thermometer.
