In addition to the errata already specified, the following may be noticed : 



In Oriani's formula for the equation of the centre, in the Milan 

 Epliemeris 1805, pp. 14 and 15, 



In the coefficient of sin 4g, 



1367 1619 



instead of - ^ -^-^ e w read - ^ ^^ e w . 



In the coefficient of sin or/,

As Delambre's formula is copied from Oriani, it is affected with the 

 same errors, and in addition to these the following errata occur : 



In the Introduction to Delambre's Solar Tables, 1806, 



In the coefficient of sin g,
