Meteorological observations {Maine Sta, Bui. 150, pp. 331-333). — The usual 

 summaries of observations on pressure, precipitation, cloudiness, and wind 

 movement at Orono, Me., and on precipitation at various places in the State 

 during 1907 are given. The mean atmospheric pressure for the year at Orono 

 was 29.84 in. The mean temperature was 41.93° F., the mean for 39 years 

 being 42.22° F. The total precipitation was 42.49 in., the mean for 39 years 

 being 43.81 in. The snowfall was 100.7 in., the average for 39 years being 91.9 

 in. The number of cloudy days was 151. " January was 3° and February 5° 

 below the a\erage', while March, April, and May fell from 1 to 3° below the 

 average. On the other hand, December was over 7° above the average for that 

 month. Other minor compensations brought the mean temperature of the year 

 within 0.29° of the average. The precipitation was very unevenly distributed, 

 with a total 1.32 in. below the average." 



Meteorological records for 1906 (Netc York State Sta. Rpt. 1906, pp. 

 JiGO-JilO). — Tables are given which show tridaily readings of the standard air 

 thermometer during each month of 1906, daily readings of maximum and mini- 

 mum thermometers at 5 p. m. for each month of the year, a monthly summary 

 of maximum, minimum, and standard thermometer readings, average monthly 

 and yearly temperature since 1SS2, monthly and yearly maximum and minimum 

 temperatures from 1883 to 1906 inclusive, and rainfall by months since 1882. 



Meteorological, magnetic, and seismic observations of the College of 

 Belen of the Society of Jesus, Havana, 1906, L. Ganooiti {Ohservatorio 

 Meteorologico, Magnetico y Seismico del Cvlegio de Belen de la Compama de 

 Jesns en la Hahana, ano de 1906. Havana, 1901, pp. 86, dgms. 3). — A detailed 

 report, largely tabular and diagrammatic, of the usual observations. 



Meteorological observations, T. F. Sedgwick (Mem. Estac. Expt. y Lab. 

 Cai'ta Azacar, 1906-7, pp. Jf5-49). — Summaries are given of observations at a 

 nimiber of points in Peru on temperature during each month of 1904, 1905, and 

 1906, and for the first half of 1907. 



The weather of the year 1905 in Hertfordshire, J. Hopkinson (Trans. 

 Hertfordshire Nat. Hist. Soc, 13 {1907), No. 1, pp. 33-ii8). — This is a continu- 

 ation of long-period obsei'vations at Watford, St. Albans, and other stations 

 in Hertfordshire, the report for 1905 being made up from observ^ations at 53 

 stations. As usual, tabular summaries are given of observations on tempera- 

 ture, rainfall, humidity, sunshine, and cloudiness, and the weather conditions 

 of each month are described. The data for rainfall are particularly full. 



" The year 1905 was, on the whole, warm and dry ; the air was of average 

 humidity, the sky rather more cloudy than usual. Though the rainfall was
