ted it, I took it off; and laying it flat on a Table, I 
divided one Side of the black Line into 9^* equal Parts 
for the 9. Days and Quarter of a Day in Venus's Year, 
and then I fubdivided each Day into 24. Hours or 
equal Parts, of which the odd Quarter contained o, 
and let the proper Figures to them. The other Side of 
the Line I divided into 12 equal Parts or Signs, and 
each Sign into 30 Degrees: By this- means I could 
ealily fee, at every Day and Hour in Venus , in what 
Place of the Ecliptic the Sun was: And putting this 
Girdle round the Globe, at an Angle of 75 Degrees to 
the Equator, eroding it in two oppofite Points, it
