c8.t14.10

17.8-17.12. *Placement of bricks in the second layer.* The method of placement is very clearly explained in these *sūtras* and is shown in Fig. 65. After placing 2 B₂s, one on each of the two eastern corners, 13 B₁s can be placed on the eastern side of the body. 10 B₄s are placed on each of the southern and the northern side. The tail contains 9 bricks, — 2 B₁s, 5 B₂s and 2 B₄s. The remaining space in the body can accommodate just 130 B₂s. The total number of bricks thus used is as follows : B₁ — 15 ; B₂ — 137 ; B₄ — 22 ; total — 174. There is a deficit of 26 bricks, which is met by B₃ bricks. According to Dvārakānātha, after replacement of B₂s by B₃s, the number of bricks of different types stands as follows : B₁ — 15 ; B₂ — 124 ; B₃ — 39 ; and B₄ — 22 ; total — 200. Clearly 13 B₂s are replaced by 39 B₃s.
