Brazen Meridian; and see how many degrees of the Equator is cut by the Meridian, from the first general Meridian, (which on my Globes pass through Gratiosa, one of the Isles of the Azores,) for that number of degrees is the Longitude of the Place.
I desire to know the Longitude of London, and close to the name London I find a smal mark 0 thus, (which smal mark is in some Globes and Maps adorned with the Picture of a Stee∣ple, &c.) therefore I do not bring the word London to the Me∣ridian, but that smal mark; for that alwaies represents the the Town or Citty sought for: And keeping the Globe steddy in this Position, I examine how many degrees of the Equa∣tor are contained between the Brazen Meridian, and the first ge∣neral Meridian; which I find to be 24. deg. 00. min.
