XVI. Improved prisons

continued

This letter,
variety of observations, economical logical, moral, and constitutional taken together: for the present those
belong to the chapter of economy
of the economical class to the economical department, as all that I
shall attempt, my Lord, to trouble you with.

Upon this abovementioned scale of ten establishments instead of one, the
expence is about midway between three times and four times
as much as it need be: say then to keep clear of exaggeration, say only three times. But
upon the Duke of Portland's plan as above stated there are to be 257
penitentiary houses instead of one: say for round numbers
only 240. If there of are excess to the amount of ten
of 10 house out of instead of one, gives makes the expence
three times as much as it need be, how many times as
much as it need be with 240 instead of one makes the expence? gives Answer,
seventy two thirty six times as much:—for the ratio of 240 to
one is 24 times as great as the ratio of ten to one: 24 times
3 is 72.

Note
If, out of the 257,
the add 17 exist already
in the improved
form, so much of the
expence in question is
already incurred and
defray'd.

But the quantity of needless expence in the poor-house
architecture, upon the current plan and scale, taking the Suffolk
Industry Houses for the standard, is but small in comparison of what it
is upon in prison architecture, taking Clerkenwell Cold
Bath Fields Prison Penitentiary House for the standard: for of that prison/Penitentiary House Cold Bath Fields Penitentiary House prison
the expence per head was found to be a little more or
about 20 times as great per head, (little more or less—
say for round numbers 21 times as great per head—) as in the proposed
Panopticon Penitentiary House: —21 times, instead of 3 times. This being assumed, the
expence quantity of needless expence in prison architecture
in the plan of 240 penitentiary houses instead of one
will, instead of 36 72 times, be 7 times 72 times, that is 504 times, as great as
it need be.

Note
(c) The calculation was grounded in the most particular
information that could be obtained from the most authentic
source. It is at Your Lordships command at any time.
