388 Ancient City discovered. 
observing, and which will afford great pleasure to several of my 
friends, as well as to many of your readers, since what I ask is not 
to be found in any of the works on astronomy which I have con- 
sulted, nor I believe any where in a concentrated form.—This is 
merely a table of the most curious and interesting objects of the 
heavens, with the telescopic powers best suited for their exami- 
nation, and the months of the year when such as are amongst 
the fixt stars may be inspected to the greatest advantage. Many 
who possess telescopes, and a taste for astronomy, suppose that 
after looking at the sun, moon and planets, they have seen all 
that their instruments can show them; while the nebule, double 
stars, and other objects of extreme curiosity are neglected, from 
a want of the knowledge of them, and the situations where they 
are to be found.—I am persuaded such a table would promote 
an interest for astronomical observation among young people, be 
considered a valuable communication by your readers ; and, if it 
could be got on to a single side to paste upon a mill-board, would 
sell separately. I am, sir, your most obebient servant,

The form in which I should put such a table would be as fol- 
lows : 
The sun at all times of the year. A dark glass must be used 
with the telescope. Is most conveniently seen either before or 
after passing the meridian, on account of his lesser elevation: a 
power of from 18 to 90 may be used to examine the spots. 
The planets—For their places, and the times when visible, see 
Ephemeris. Mercury and Venus must be viewed with a low 
power, and the object-end of the telescope shaded by about six 
inches of additional tube, which may be made of paste-hoard. 
Then give similar directions for the moon and other planets. 
Then take the months regularly, and under each place the sideral 
objects which are about the meridian in that month. 
ANCIENT CITY DISCOVERED. 
In the year 1772 excavations were by order of the French 
Government made in the small hill of Chatelet in Champagne, 
on the site of a Roman town destroyed in the wars of Attila, but 
preserved in part by being covered with earth. Many of the cu- 
rious articles there found are preserved in Paris in the house of 
Abbé Tersan, a veteran of fourscore, who is occupied in getting 
engravings from them for general circulation. An official report 
by M. Grignian presents some interesting details respecting this 
excavation. The remains of about 90 houses, eight small crypts 
or subterraneous chapels, with a number of cellars, cisterns and 
wells, were discovered. The streets, which were regularly paved, 
and quite straight, were only from 15 to 20 feet in width: the 
pavement,
