and also accomplishing his diurnal reyolution. This is aremark- 
ably complicated piece of machinery, none of the figures being 
more than an inch in length. 
The third is a cage, very large and highly ornamented. On 
the top is a black man who beats time to the chiming of several 
Satyrs and two monkeys, one of whom grins quite ludicrously, 
But the most wonderful things are two Canary birds that sing the 
natural notes of these birds, flutter and flap their wings, and 
Spring from one perch to another. In this cage is a fountain, 
which falls by several stories ; and the artificial arrangement of 
pieces of glass represents so naturally the sound and glitter of 
falling water, that both the eye and the ear may be deceived. 
The fourth is a park with two country seats, out of which 
come two ladies, who exchange mutual salutations, and bow to 
the company. Attracted by the sudden flight and song of a bird 
in a grove beside them, they turn and listen. The bird, not 
larger than a bee, sings and flutters for some time, and then flies 
away among the trees. Upon this, the ladies repeat their bows 
and curtsies to each other and to the company, and withdraw 
to their houses. On the top of the dome above, is a large but- 
terfly, which closes and expands its wings and moves its feet ina 
rfectly natural manner, This and indeed all the machinery 
Bis a variety of tunes, 
The fifth and sixth are two magicians, the French and the 
American. ‘There is a set number of questions to each; and on 
y one of these being placed in a drawer for the purpose, the 
magician goes through a variety of ceremonies and gives the an- 
swer, which is always appropriate. It is said that several cele- 
brated mechanicians have been allowed to take these machines 
D pieces, yet have never been able to discover by what contri- 
ince the right answer js always given, 
‘The last is called a perpetual motion; although perhaps the 
power that it possesses is not strong enough for any application 
P extensive machinery. It consists of a large wheel, around 
le edge of which are placed at equal distances a certain num- 
ler of moveable hollow cylinders, each containing an equal pro- 
ion of quicksilver, The weight of the quicksilver, which 
1e other as the wheel turns, determines 
€ horizontal or perpendicular position of the cylinders. B 
ir horizontal position, in falling, the circumference of the 
eel is continually enlarged on one side, and diminished on the 
t by their perpendicular position in rising ; this creates two 
lequal semicircles, the one more eccentric than the other, and 
Mis causes a perpetual rotation,
