of barrows, a total of sixty-two thousand seven hundred and forty-
eight skewers daily would be obtained. Allowing that, of these
sixty-two thousand seven hundred and forty-eight skewers, the odd
two thousand seven hundred and forty-eight were accidentally
devoured with the meat, by the most voracious of the animals
supplied, it followed that sixty thousand skewers per day, or the
enormous number of twenty-one millions nine hundred thousand
skewers annually, were wasted in the kennels and dustholes of
London; which, if collected and warehoused, would in ten years'
time afford a mass of timber more than sufficient for the
construction of a first-rate vessel of war for the use of her
Majesty's navy, to be called "The Royal Skewer," and to become
under that name the terror of all the enemies of this island.

'MR. X. LEDBRAIN read a very ingenious communication, from which it
appeared that the total number of legs belonging to the
manufacturing population of one great town in Yorkshire was, in
round numbers, forty thousand, while the total number of chair and
stool legs in their houses was only thirty thousand, which, upon
the very favourable average of three legs to a seat, yielded only
ten thousand seats in all. From this calculation it would appear,-
-not taking wooden or cork legs into the account, but allowing two
legs to every person,--that ten thousand individuals (one-half of
the whole population) were either destitute of any rest for their
legs at all, or passed the whole of their leisure time in sitting
upon boxes.
