A reply to a question in Notes & Queries yesterday recommended purchasing lion and tiger urine from Chester Zoo to stop neighbourhood cats from urinating in a vegetable patch. Chester Zoo would like to forestall requests for its big cats’ urine: it asks us to make clear that it does not in fact sell either tiger or lion urine. Many years ago the zoo sold elephant dung, but it no longer does.
A report on the tin market said that 1 tonne of tin – current price £9,000 – could produce 2,500 standard cans. Surprised readers pointed out that each can would cost £3.60. The estimate by Barclays Capital was based on this calculation: take 1 tonne and divide it by a sample weight of 400g per can to yield 2,500 cans. In fact 400g is a typical weight for the food inside a standard can, not the can itself.
