There's another thread, which tries to start some evaluation for a flat earth map.

In Earth not a Globe there are already some calculations for it.

http://www.sacred-texts.com/earth/za/za22.htmTop prerequisite - mentioned in the 1st paragraph:

... constitutes an IMMENSE NON-MOVING **CIRCULAR** PLANE.

We need that for the next calculation.

Let's start at the bottom:

would make the total radius of the earth, from the northern centre to the farthest known southern circumference, to be 5224 statute miles. Thus from purely practical data, setting all theories aside, it is ascertained that the diameter of the earth, from the Ross Mountains, or from the volcanic mountains of which Mount Erebus is the chief, to the same radius distance on the opposite side of the northern centre, is more than 10,400 miles; and the circumference, 52,800 statute miles.

So if the radius is 5224 miles, the diameter is 10,400 miles, ok, but how did he calculate 52,800 statute for the circumference? 10,400 * 3.1415 = ?

Some paragraphs above:

And as the distance from the polar centre to Valencia in Ireland is shown to be 2556 statute miles, the direct distance from Valencia to Cape Town is 1164.

1164 miles south of Ireland? Ask some sailors: This approximately is a point west of Gibraltar. Didn't great R. find any itineraries for e.g. England to Gibraltar?

But lets have a look some paragraphs above, where great R. himself contributed evidence, that does not match this result.

As the distance from Melbourne to Cape of Good Hope is 7140 nautical miles, as shown by the log of the Great Britain, and as the whole distance from Melbourne to Liverpool was 14,688 nautical miles, it follows that, deducting 7140 from 14,688, that the passage from the **Cape of Good Hope to Liverpool was 7548 nautical miles.**

(7548 nautical miles are 8688 statute miles)

So the steamer Great Britain sailed 8688 statute miles from South Africa to England, whereas Cape Town is only 1164 statute miles south of Ireland?

Ok, the Steamer had to go around West Africa, as only Ships of the Desert can cross the Sahara, but nearly 8 times the distance?

And here again:

From England to Adelaide is here stated as 14,000 nautical, or 16,333 statute miles; and as the difference of longitude between Adelaide and Sydney is 23 degrees, equal to 1534 statute miles, we find that from England to Sydney the distance is 17,867 statute miles. Taking from this the 7548 nautical, or **8806** statute miles, we have again 9061 statute miles as the distance between the Cape of Good Hope and Sydney.

If the total trip is 17,867 statute miles and it takes 9061 statute miles as the distance between the Cape of Good Hope and Sydney, the distance from England to Cape of Good Hope must be 17,867 - 9061 =

**8806** statute miles.

So in summary we have

- an author, who has problems to calculate the circumference of a circle from it's diameter.
- Presented evidence that shows the sailed distance from England to Cape Town as about 8,000 miles, whereas the calculated radius of Flat Earth is only 5224 statute miles. Not to mention, that Ireland/England is about 2,500 miles south of the North Pole (which also can be found in this chapter of EnaG) and Cape Town also is way north of Antarctica.
- And the ridiculous result, that Ireland is only 1164 miles north of Cape Town.
