tion; to obtain which with facility, the 
weight should be fastened in such a man- 
ner us to be moveable out and.ain, up- 
wards and downwards, &c. when -ad- 
Justing it, the proper weight and quantity 
of the counterpoise should be found by _ 
trials, as the weight and size of different 
time-pieces ‘are not alike.” In that re- 
commended by Mr. S. the box contain- 
“ing the watch is three quarters of an inch 
high, and the distance from the steel 
centre, is one inch and seven-cighths 
long: the counterpoise is one inch and a 
quarter in diameter, and half an inch 
high; and the distance from the. steel 
centre is two inches and ‘one-eighth of an 
inch long, the weight fixed to the hour- 
hand wheel, forms a semi-circle, and is 
the one-eighth of an inch. thick: the 
whole rests upon two ornamental and 
jewelled supporters, or friction rollers, 
which are screwed upon a stand, upon 
which is also fastehed a supporter for the 
rim, serving asa dial, which may be. di- 
idea into Weve, or twenty-four hours, 
according to the construction of the 
time-piece; the hours and minutes are 
shewn by one hand only, or, if required, 
a nonius may be applied to subdivide the 
minutes, The centre piece serves to 
represent the sun. To use this apparatus 
as a nocturnal dial, the reflector is fixed

to the steel centre, and is confined within 
the ornamental case or vase, that con- 
tains the lamp.and magnifier the hand — 
shewing the hours> is. fixed within the 
case. By this contrivance, the watch 
work is not exposed to the heat-of the 
Jamp, as in the manner described with 
the double dial. ‘To represent the in- 
ierease and décrease, as wellas the re- 
gular revoiution of the moon round the 
earth, ah apparatus is fixed to the back 
of the globe or box, in. such a manner 
‘as to make the moon invisible when be- 
tween the sun and earth, and then, 
“when turning round, evadually to in- 
crease, shewing the phases on the pra- 
per day; for which reason, the number 
_of days in the month are engraved upon 
a brass circle, fixed round. the globe. 
The motion is effected by a little weight 
fixed to the axis of a pinion, with, six 
teeth, this pinion acting into a. wheel 
-with thirty teeth. To the axis of this 
wheel is attached the bent arm of the 
moon, the other end of this arm serving 
asa counterpoise to the weight of the 
moon; this apparatus, turning round 
with the. box or globe, oceasiuns “the 
pinion to be turned by the weight, ai- 
ways hanging perpendicularly, and there- 
by causing the wheel, with the moon, to 
move one tooth every day.
