As the latitudes were necessary for computing the azimuths, they 

 were first had spherically for the two stations at Mullapunnabetta 

 and Yerracondah^ by taking the westing and easting from the me- 

 ridian of Save7idroog, and converting them into parts of great circles. 

 These came so near the truth, that on recomputing the azimuths 

 by the latitudes finally brought out, there was no sensible dif- 

 ference. 



It may be remarked here, that no double azimuths have been 

 taken. The pole-star being so low, and the vapour in the atmo- 

 sphere so great in general, that I have never, except in two in- 

 stances, been able to discern it while the sun was above the horizon.
