nature, it is therefore extremely improper to make ufe of 
any divilion of it which does not coincide with the fcale 
of our arithmetic. The divifion of it into io hours, the 
hour into ioo minutes, and the minute into 100 feconds, 
is the moll fimple.” Accordingly, the author has given 
an engraving of a clock-face, whereon the outer hour- 
circle is marked with numbers from I to X only, for day 
and night; and the inner one with figures from i to u 
twice over. His defign in this he explains as follows : 
“ If the hour-hand of a clock or watch be contrived to 
make but one revolution in a whole day, this hand might 
carry an artificial fun, with a wire projecting from it, 
pointing to the circumference of a circle, upon which 
may be graduated X decimal hours, and cutting the cir¬ 
cumference of a finaller concentric circle, upon which 
may be graduated twice ii vulgar hours. If the minute- 
hand of a clock be contrived to make but io revolutions 
in a whple day, this hand might cut the circumference of 
a larger concentric circle, upon which may be graduated 
ioo decimal minutes, and point to the circumference of 
a Hill larger concentric circle, upon which may be gra¬ 
duated 144 vulgar minutes. Since the hour-hand carries 
an artificial fun, it is necelfary that the upper part of the 
dial Ihould reprefent noon, and the under part midnight; 
and confequently, that the decimal minutes fet out from 
100, which is l'uppofed to be placed over X, but which is 
omitted, becaufe the decimal hours exprefs the numbers of 
tens of minutes wdiich Hand over them ; thus, over III 
is 30; V, 50; VII, 70; &c. When the hour-hand ar¬ 
rives at any decimal hour, the minute-hand is alwaysat 
X (or 100) ; but, on the arrival of the hour-hand at each 
vulgar hour, the minute-hand is in a different fituation. 
When the hour-hand arrives at either 12, the minute- 
hand is at the la underneath. 
“ Becaufe the minute-hand makes 10 revolutions in a 
whole day, and Jjof 10 22 ^ ; therefore, when the 
hour-hand arrives at 1, in the vulgar hour-circle, the mi¬ 
nute-hand has defcribed of a revolution, at which 
place 1 is marked in the vulgar minute-circle; which 
(hows that, when the hour and minute hands are both at 
1, in their refpeCtive circles, it is then 1 o’clock vulgar 
time. In the fame manner, when the hour and minute 
hands are both at 2, in their refpeCtive circles, it is then 
2, vulgar time; if both at 3, then 3, vulgar time, See. 
Hence the vulgar minute-circle is of necefiity divided 
into 12 parcels of 12 minutes each, or 12 dozen mi¬ 
nutes.”

All this is very ingenious. The chief objections to ; 
fhefe excellent fchemes are, that they are propofed rather 
too late. The prefent race of mortals will not be more 
inclined to diruinifli the number of hours in a day and a 
night from 24 to 10, with the prefent author, (who calls 
himfelf, R. C. efq. B. A. late qf Chrift College, Cam-, 
bridge,) than to increafe them, with our ingenious friend.
