Note 2 — Chapter XIII
Reading edition
We must except a low, narrow door, through one of the turrets at the south-west angle, the mode of constructing which will appear in page 367. It seems to have been intended as a sally-port and one person only can pass through it at a time. From the remains about this angle, there appears to have been an outer wall of very inferior strength, but it seems to have made no part of the original plan.
