    METEOROLOGICAL OBSERVATIONS FOR THE YEAR 1927. Latitude 36° 6' N. Longitude 5° 2L W. Instruments verified at the National Physical Laboratory, Kew. The Meteorological Station is situated in an obsolete bastion on the fortifications on the South-West side of the Rock, the height of the ground being 50 feet above mean sea level. Here all the instruments (except the anemometer) are kept. The shade thermometers, kept in a Stevenson screen, are: one self-recording maximum, one self-recording minimum, a dry and wet bulb. A self-recording grass thermometer is used for registering the temperature on the grass. The rain gauge is an 8 inch copper meteorological pattern. The anemometer is fixed in Victoria Gardens, North Front, on the isthmus which joins Gibraltar to the mainland, and clear of the Rock to avoid eddies. A report is sent twice daily to the Meteorological Office, London, and daily to the Gibraltar Chronicle for general information. A comnlete monthly report is also sent to the Meteorological Office, London, for publication in their journals. The report contains statistics showing the means for the year in barometric pressure, air temperature, rainfall, humi¬ dity, cloud and wind, compared with the averages for a series of years, number of days of clear sky, overcast days, and days on which rain fell during the year. Readings are taken every day throughout the year at the 7th, 13th, 18th and 21st hour, but the following tables are compiled from the readings at the 7th, 13th, and 21st hours only. NOTABLE FEATURES OF THE WEATHER OF 1927. JANUARY was normal in temperature and much below the average in rainfall. Fine generally with strong Westerly winds, including a heavy gale on the 18th. FEBRUARY normal in temperature, but wet, and at times very windy, with thunderstorms, and hail.
