The course of observations remains unaltered. With the Meridio- 

 nal instruments, the moon has been observed at every practicable op- 

 portunity ; the larger planets whenever they pass the Meridian be- 

 tween the hours of 5 a. m. and 11 p. m. ; and care has been taken to 

 carry forward the observations into the day so long as the planets can 

 be seen and to commence again with them as soon after noon as they 

 can be distinguished. The lesser planets at every opportunity ; the 

 stars of the Nautical Almanack have been observed, and a large num- 

 ber of small stars taken from the Catalogues of the Astronomical 

 Society, and from those of Piazzi and Bode, ten observations being 

 considered the least number to be made on each star before it is relin- 

 quished in favor of another. 



The Magnetical and Meteorological observations have been continued 

 on the plan recommended by the Committee of the Royal Society. 

 The Declinometer, the Horizontal and Vertical force Magnetometers, 

 the Barometer and the wet and dry Thermometers have been observed 

 every two hours day and night, Sundays excepted — the dew point at 

 every four hours throughout the season of the hot winds when ice was 

 obtainable, and when a comparison of it with the results obtained from 

 the wet bulb Thermometer is of most value : the great expenditure of 

 Ether, at other seasons almost precluding its observation throughout 

 the whole year. The Dip has been observed twice on each Tuesday 

 and Friday. The self-registering Anemometer has been in constant use. 



Absolute intensity observations have been made from the month of 

 February, when the temporary instrument before mentioned was com- 

 pleted : and temperature experiments on the loss of Magnetic moment 

 of the bars from accession of heat, were likewise then made. 



I have made arrangements by which, without any increase of expense 

 to the King, the principal Magnetic and Meteorological Instruments 

 will be observed throughout the present year at every hour, instead of 

 every two hours. 



The reduction of our observations remains much more in arrear than 

 I could wish, but compared with the same period last year we have 

 gained very considerably ; the whole of the magnetic and meteorological 

 observations for 1842 and 1843, having within the last twelve months 

 been transmitted to England, and a large portion of those of 1844 being 

 in a state of considerable forwardness. When the arrears iti this
