Dnivers. Avril 1824. 
53. American Geography.—A Geography of the United 
States has just been published in Germany, in one volume, 
of 1200 pages, in which the author has availed himself of the 
latest information, such as the geographical and statistical 
atlas of Carey. The work concludes with an alphabetical 
table of 130 pages. ‘‘This table,” says the reviewer, 
‘shows how fond the Americans are of particular names- 
We find that there are already in the country, twenty Fair- 
fields, ten La Fayettes, without reckoning two Fayettevilles, 
six Frankforts, eight Lancasters, nineteen Monroes, forty-two 
Franklins, and fifty-five Washingtons! What confusion will 
one day arise, when all these places shall have acquired some 
importance ? It will be necessary to recommend to corres-

sisting of a hollow sphere of forty feet in diameter, within 
which is laid out a general map of the world, executed by the 
best artists. A spiral staircase ascends to three circular 
and insulated balconies, whence the spectators can view 
every part of the sphere, even in it most minute details.—

55. Deaf and Dumb.—Observations de deux sourdes et 
muettes, &c or ‘* observations on two deaf and dumb persons 
who hear and speak, proving that many of the deaf and dumb 
may enjoy the same benefit.” A pamphlet under this title, 
published in Paris, forms the fourth memoir relative to dis- 
eases of the ear, by Dr. Deleau, jun. of the faculty of that city- 
It consists chiefly of a report made to the Academy of Sci- 
ences by M. M. Pelletan and Percy, in December 1822, and 
of two observations made upon two young girls, one nine, and 
the other eleven years of age, curedof deafness, and restored
