NEATE'S OBSERVATION OF THE TRANSIT. 



369 



From Lieutenant Neate's telescopic observations we obtain the following 

 results : 



Assuming Latitude 19. 40'. 21'H ; Longitude 4 h . 13 m . 43 S -0 East. 



For the " disappearance of the ligament " at Ingress, taking R = 976"'80, 

 r 31"-42, we have the equation 



+ 7"-38 = +"-1937 n -6io38R.A. -7498 8N.P.D. o"-o3o6 S t I R + S r. 



For the " formation of the ligament " at Egress, taking E = 976"'82, 

 r = 31"-42, we have 



+ 4"-i3 = "-0274 n -2176 S R.A. '9718 8 N.P.D. +o"-o322 8< 8R + 8r. 



The final longitude being O5 further East than that adopted in computing 

 the Greenwich Sidereal times above, a correction is required to these 

 equations, which is obtained by making 5 t = + O s- 5. 

 8 R.A. is expressed in seconds of arc.
