gress of publication by the Vienna Observatory, have not yet 



been received. 

 V. Lalande, H. C. See subsequent discussion. 

 VI. Bessel in his zones never observed so low as the actual Lever- 



rier region. 

 VII. Paramatta Catalogue, seldom observed north of — 38°. 

 VIII. Madras Catalogue. Mr. Taylor confined himself chiefly to 



reviews of Baily and Piazzi. 

 Thus it appears, that though doubtless Leverrier has been seen by 

 some of these authors, still the Histoire Celeste afforded the only 

 chance of easily finding an observation of this planet. For limits of 

 e < 0.06, the only nights in which Lalande had Leverrier in his 

 region, were the 8th and 10th of May, 1795. For the latter date, 

 Mr. Walker computed the locus of Leverrier, for various eccentrici- 

 ties, and for ii= «, as in the following table, in which Leverrier's R. 

 A. and Dec. are for the mean equinox of 1800, to correspond as a 

 star to Hussey's XlVth Hour.

Mr. Walker then formed the following catalogue of all the stars in 

 the H. Celeste, May 8th and 10th, 1795, within 15' north or south 

 of the locus of Leverrier, a.s follows:
