508 The King of Oude's Observatory at Lucknow* [June, 



the necessity of placing it on the pillar designed for an instrument of 

 this description by my predecessor Captain Herbert, but whatever the 

 advantages gained by an elevation of 35 feet above the ground in 

 enabling the observer to command a more uninterrupted view, they are 

 more than balanced by the disadvantage of the optical power of the 

 Telescope being impaired by the vibrations to which so high a pillar 

 of brick-work must always be liable ; and I fear that this beautiful 

 instrument cannot while so placed be applied to all the purposes for 

 which its great power would otherwise fit it. 



In the Magnetic Observatory the arrival of the vertical force and 

 inclination instruments has enabled me since the month of April to 

 make the daily routine of observations correspond with that of all the 

 Magnetic Observatories established by Government. 



With respect to the subjects on which the instruments are employed :— - 

 The observations of the planets are, at the suggestion of the Astronomer 

 Royal, carried forward into the day as much as possible, the lesser 

 planets are likewise at his suggestion carefully observed, and I believe 

 that favored by our climate, we are more successful in frequently seeing 

 them than they are in Europe. Besides the principal stars for latitude, 

 &c, the Zodiacal stars, in number about 500, comprised in the cata- 

 logue of Caturegli, have been observed, as also those pointed out by 

 Mr. Baily as requiring observation ; and the re-observation has been 

 commenced of the stars of the 3rd and 4th volumes of Mr. Taylor's 

 Madras observations. We have in fact made more observations than 

 we can easily reduce. 



In the Magnetic and Meteorological Observatoiy, observations are 

 made throughout the 24 hours, at each even hour of Gotting-en mean 

 time in accordance with the instructions of the Committee of the Royal 

 Society. The term days have been kept and a few instances of mag- 

 netic disturbances have been observed in accordance with the same 

 instructions, at every 5 minutes. The periodic experiments on intensi- 

 ty, I am sorry to say, have not yet been included for want of a dupli- 

 cate instrument on the "Auxiliary" one especially adapted to the 

 purpose, which has been ordered from England some time past, but 

 has not yet arrived. I hope, however, partly to make up for the defi- 

 ciency by means of a temporary instrument which I have had construc- 

 ted at Lucknow.
