Mean Result. 

 Position 51' 18' 5/; Distance io''.86i; Epoch 1824.99. 



This star was re-measured unintentionally ; I was not 

 aware that observations of it were communicated in the 

 former memoir, which give for the Position 52° 4' sf; and 

 Distance 9".790 ; Epoch 1821.96. The positions agree very 

 well, but the distances differ more than could be wished. 



No. IV. R. A. 6^ 20"° ; Decl. 6^ 55' S. 

 11 Monocerotis; H. andS. 71. 

 Triple ; perhaps quadruple ; but the fourth star is very dis- 

 tant. A 6^, B 7th, C 7t, and D of the 10th magnitudes.
