ASTRONOMY. 
1. Second Comet of 1819. — On the 12th of June 1819, M. 
Pons of Marseilles discovered a small comet in the Lion. It is 
invisible to the naked eye, and has no appearance of a tail, and 
a very indistinct nucleus. 
His observations were as follows :

M. Gambard concluded, that on the 24th July, the distance 
of the comet from the Earth would be only about the 20th part 
of the distance of the Sun. 
2. New Orrery . — The Reverend G. Tough of Ayton has 
lately constructed an Orrery of a much improved form, which 
exhibits great ingenuity and mechanical skill. 
1^^, It consists of a large glass globe, mounted on a brazen 
stand, and splendidly illuminated with circles, golden stars, &c. 
which exhibit an interesting picture of the Heavens ; and at the 
same time, containing within it all the planets and satellites, ad- 
justed to true time, according to the latest discoveries. It dis- 
plays the solar system in motion, together with its relation to 
the celestial sphere, as in nature. 
2d, The movements being inclosed within the glass globe, are 
thus effectually secured from injury ; and the beauty of the ine-
