Reference to the plan ratio table at the commencement, and to the tables here introduced, will shew that most of the primary triangles mentioned are indicated on the plan ratio table principally by the lines corresponding to the ratios of the satellites. Thus—

PRIMARY TRIANGLE	INDICATED BY
17, 144, 145.	Triangle FP, PA, AF on plan.
13, 84, 85.	Plan ratio of SJ to SU, 7 to 6.
11, 60, 61.	Plan ratio BC to FB, 6 to 5, and DN to NR, 61 to 60.
12, 35, 37.	Plan ratio EO to AY, 37 to 12, and EA to AY, 35 to 12.
5, 12, 13.	Plan ratio CY to BC, 3 to 2; JE to EX, 3 to 2; CA to YA, 5 to 1; and NZ to ZA, 12 to 5.
8, 15, 17.	Plan ratio FB to BY, 5 to 3, and AC to BC, 15 to 8.
33, 56, 55.	Plan ratio YX to AY, 7 to 4; AB to BO, 7 to 4; and EA to AZ, 7 to 4.
28, 45, 53.	Exists on plan, AB, BJ, JA.
3, 4, 5.	Pervades the plan, and is also indicated by plan ratio GX to DG, 2 to 1; SU to SV, 2 to 1; and CY to YZ, 3 to 1.
48, 55, 73.	Exists on plan, FW, WV, VF—and is also indicated by plan ratio FO to OZ, 8 to 3.
65, 72, 97.	Plan ratio AC to CH, 9 to 4; MY to YZ, 9 to 4.
20, 21, 29.	Exists on plan FB, BA, AF; and plan ratio, GU to DG, 5 to 2.

It seems probable that could I add to my pyramid plan the lines and triangles that the missing eleven pyramids would supply, it would comprise a complete table on which would appear indications of all the ratios and triangles made use of in right-angled trigonometry, a "ratiometer" in fact.

I firmly believe that so far as I have gone it is correct—and it is possible, therefore, with the start that I have made, for others to continue the work, and add the eleven pyramids to the plan in their correct geometrical position. By continuing the system of evolution by which I defined the position of Cephren, and the little pyramid to the south-east of Cheops, after I had obtained Cheops and Mycerinus, may be rebuilt, at one and the same time, a skeleton of the trigonometrical tables of a forgotten civilization, and the plan of those pyramids which are its only link with the present age.
