Authors define the year as "presenting anomalies that do not permit show the general climatic laws of the country. The months of December January and February were hot and dry as 1804, and these conditions have spread to northern Bogota and southern Peru." The temperature was taken 3 times a Day (7h, 14h and 21h) with a Celsius thermometer; the mean temperatures were computed after Kaemt (1843). But the bulletin only shows the monthly minimum, maximum, mean and oscillation temperature. The relative humidity (maximum, minimum and mean) was calculated with the August tables (August, 1830) from a wet and a dry thermometer observed three times a Day (6h, 14h, 21h). The barometer was compared with the barometers of the Paris observatory and corrected in five tenth of millimetre. The bulletin gives the monthly mean, minimum and maximum atmospheric pressure reduced to 0°C. Wind direction was measured three times a Day in an eight directions compass. The Precipitation was measured daily (24 hours) but only the monthly Precipitation is given in the text. The largest daily rainfall took place in February with 46 mm. They do not correct the Precipitation measurements by altitude but cite that the rain gauge was 17m above the ground. April 1865 (482 mm) and August 1864 (137mm) are clearly above the maximum monthly Precipitation registered in the observatory series 1891-1985 (maximum April 309 mm in 1917, and maximum August 100.1 in 1981). The instruments used by the Jesuits were done in Paris in the workshops of Lerebours and Secretan, builders of the imperator, and compared with the instruments of the Imperial Observatory. The instruments were: one Fortin Barometer, one Gay-Lussac barometer, four thermometers scaled in the glass in tenth of grade, two Negretti Thermographs, one udometer epruveta, one electric anemometer, one declinometer, a suspension planchet, one spectrometer and one Volta electrometer.
