That the Inspector's head as he passes may be elevated above
the heads of the Prisoners as they pass as high as possible the top
of his passage should be the crown of the arch and the floor as little
below it as possible: viz: the passage should have the same height as the
Gallery from whence it is projected, and no more: say
about 6-9. By
giving it an arched
curvature on each side
he will have the better
view of the prisoners as
they pass – by looking
down on them instead
of looking at them horizontally.

In the Inspector's passage
must be small sight
holes every two or three
foot on each side. They

might be composed or iron or copper conical rings a few inches in diameter. To prevent
the thorough light they should be not opposite on the different sides, but alternate.
The Prisoners passages being kept perfectly which, it is supposed he
would have a tolerable view of them.

As the three passages advance towards the exit they widen
insomuch that at the exist their dimensions may be as follows

Inspector's passage Walls as before each 6 inches – 1
Clear space in do. – 4-2
Passage for Male prisoners – 4-2
Do. for female Do. – 4-2
13-6

If Are supports wanted?
If so might not the walls of the Inspectors passage, at the exit
terminate on each side in a hollow iron pillar?

Could the arch designed for the exit be made a little wider
than the rest at the expence of the two arches on each side?
