* This angle of M. Struve differs unaccountably from all the rest : it is a mean 
of two night’s observations, however, in each of which two measures were taken, 
and whose results only differed o°.i or 6' from each other. Moreover, it is corrobo- 
rated by an observation of 1 821.78 (Dorpat Obs. iii.) which makes it 36° 24'.
