Looking at Pg.16, Fig. 9 At A we see the Earth with 40075 Km Circumferential distance and at B converted to 86400 Chkm (L= l Length). At C we see half of A’s Circumferential distance i.e. 20037.5 km at D we see half of the distance at B and 20037.5 km converted into 43200 Chkm (E= 1 Extent). At E we see the distance of 43200 Chkm converted into a elliptical shape. At F this is shown as a regular circle having 43200 Chkm = 1E. At G, F is repeated and divided into 12 parts, (this depicts half the Earth’s Circumfrential distance i.e.43200Chkm = E). At G’ we see the magnification of one of the 12 divisions (between 12 and 1) which also gives us 3600 Chkm = 1 Basic (B) divided further into 5 parts each of 720 Chkm and which is further divided into 12 divisions, such that when we multiply these 12 divisions by 5 divisions we get 60 divisions each = 1 Range ( R ) and finally 1/12 of 720 which is 60, which in turn gives us 60 Portions each = 1 Portion ( P ) so that when we multiply 60 P by 60R we get 3600 Chkm. At H we have constructed a Distance Piece of 60 Chmm (not to Scale) circumference having similar divisions as shown in figure G.
43200 Chkilometers x 1000 = 43,200,000 Chmeters
scaling down by 1000
43,200,000 = 43,200 Chmeter
1000
43,200 Chmeters x 1000 = 43,200,000 Chmillimeters
scaling down by 1000
43,200,000 = 43,200 Ch millimeters
1000
\43,200 Ch Kilometers scaled down by _ 1__ x __1___ = ___1____

43,200 Chmm ¸ 12 = 3,600 Chmm 3,600 Chmm ¸ 60 = 60 Chmm
We have now a dial of 60Chmm circumference divided into 12 parts, further divided into 5 parts see Page 16 figure G - G’. [See also Page 14, Fig.7]
