EE SULTS 



OF THE 



METEOROLOGICAL OBSERYATIONS MADE AT BRUNSWICK, MAINE. 



ATMOSPHERIC TEMPERATURE. 



The temperature of the air was observed three times a day, at the hours 7 A. M., 

 1 P.M., and 6 P.M., between November, 1807, and December, 1859, inclusive. 

 The record of the year 1853 is missing. OtherAvise there are but a few omissions. 

 The record of the period August, 1856, to May, 1857, is in many places damaged 

 by fire, though mean values, which were written on slips of paper, are preserved in 

 many instances. Table I contains the daily mean values of the temperature 

 uncorrected for diurnal variation, and expressed in degrees of Fahrenheit's scale. 

 When but one or two observations were found recorded in a day, the missing num- 

 bers were supplied by interpolation ; this had ju.diciously been done by Prof. Hop- 

 kins by paying attention to the diurnal variation as well as to the readings of the 

 days preceding and following at the hour required ; these cases, however, are not 

 numerous.^ When no observations are recorded for several days in succession, not 

 exceeding six, however, the omission was supplied by simple interpolation ; aU 

 numbers thus obtained are distinguished in the table by brackets ( ) . A few other 

 defects, extending over a month and fraction of a month, were remedied by the 

 insertion of the daily means resulting from the whole series of over 50 years ; these 

 means are inclosed within rectangular brackets [ ]. 



DaUy maxima and minima of temperature are recorded for January, February, 

 and March, 1807, and again between November, 1807, and January, 1818; this 

 last record is rather irregular. The instrument used was a Sykes' thermometer, 

 exposed on the northern side of the building, five feet from the ground. The 

 locality was at first bare of vegetation, but in the course of time shrubbery and 

 trees grew up. 



* The daily and monthly means were made out by Prof. Hopkins, who had also commenced 

 transcribing monthly maxima and minima, and collected statistical information respecting wind, 

 weather, and rain. 



1 January, 1867.
