Putting a finger on how to weigh hands

I was intrigued by Emma Beddington’s article on the weight of human hands (14 August). I would love to learn how she was able to ascertain the values of 409g and 426g respectively for right and left mitts without amputation. The only other way I can think of is partial immersion in water and the invocation of Archimedes, but that would need a very special balance.

• Like the Jaffes (Ryanair charges elderly couple £110 after they download wrong boarding cards, 15 August), I made an error in a travel booking. I booked my car on to the 02:00 Dublin to Holyhead ferry, but joined the queue for the 2:00pm sailing. I was mortified by my mistake at check-in, but the officer said: “No charge. Don’t worry, I’ll get you on. We’re not Ryanair.”

• Jacqueline Wilson says younger readers do not have “a sense of history” (Report, 14 August). How can they acquire one if they are shielded from attitudes of the past by the rewriting of books?
