 there were two of the new planet Uranus. The more he was 

 entreated to communicate them to the public, the more ob-

 broke out, Lalande, who was exceedingly anxious for the 

 prefervation of thefe papers, made an attempt to get them 

 into his pofleflion ; but his exertions were fruillefs. He could

 was therefore afraid that, as no one but himfelf knew where 

 thefe papers were hid, the old man, through mental debility, 

 might forget where he had placed them. Le Monnier left 

 three daughters, all married; the fecond of whom was mar- 

 ried to the celebrated mathematician La Grange on the 31ft 

 of May 1792.
