Amongst the random ephemera I've picked up on eBay is this 1902 booklet of the Rules, Orders and Regulations of the London Cemetery Company, relating to their two cemeteries at Highgate and Nunhead. You can download a PDF of the complete booklet here.
I'm devastated to see that
All ... cameras ... must be left with the Gatekeeper during the time that the owners thereof remain in the Cemetery.
We also see the price changes over the first sixty years of Highgate's opening: in 1842, interment in a common grave was £1/5/- (one pound, five shillings); in 1902, £1/10/-. Ground for a grave 6 foot 6 by 2 foot 6 was £3/3/- in 1842; by 1902, it's £3/8/-. 5 shillings seems a very small increase, but in fact, it's not: according to the Bank of England, inflation over that period averaged -0.1% per annum: prices fell. So the expensive burials are getting even more expensive.
