The old Observatory, founded by subscription in L776, was not com- 

 pleted until 1792. No Observations were ever made there. The new 

 observatory was projected in 1812, and erected on shares in 1818. The 

 municipality donat.'d the ground. In 1834, the founders ceded its ad- 

 ministration to the State, and in 1846 made over the ownership. Time 

 signals have been given there since 1855. Since 1872, the firing of a 

 cannon has been substituted for the former ball. • ■
